LSR Pro Stock "Spyder" 2-1's

No 1950's megaphones, No Aluminum Butt Plugs

Built Baggers...the new norm. Hot rod motors in 900 lb sleds. If you want a pure race system that you can cover miles with this is the most sophisticated choice. A high velocity merge collector and a high velocity secondary that maximizes scavenging. A 4" tail section with high bypass muffling that clears the rear bags. A race system you can live with on your 150hp couch.

Shorter 4" Tail section pictured above.

We also make these for T143 motors with or without additional sound attenuation.

In the late 70's, all through the 1980's and into the mid 1990's we used to spend about 5 months out of every year tuning things. No time for that anymore. It's best that you tune your own bike...add up the hours and write yourself a hot check. Or just pay somebody. We use a Supeflow CycleDyn Dyno and we ride in the real world using our RSR Air Fuel Ratio Gauges.

When you order the TTS MasterTune, a LSR 2-1, and our RSR Air Fuel Ratio gauge,  and a TTS Camshaft (see below) there is a $100.00 discount. Real world.

 

TTS M8 Camshaft left above. Mercedes / Illmore pushrod V8 Indy winning 265E camshaft to the right. Pay attention to the lobe design.

Ilmore found that with a pushrod design there was so much monkey motion going on between the camshaft lobe and the actual valve opening that it made more power and torque to gently (preload if you will) open and close the valve. Slamming the valve open introduced disastrous harmonics and accelerated valvetrain wear.

Steve Cole designed his TTS 100/150/175/200 camshafts plotting the acceleration rates contrary to what others did i.e. banging the valve open and shut. Years later Steve finds others are copying his designs even if they do not know why he designed them that way. Camshaft descriptions.

If you actually ride instead of parking and talking about your dyno session you will find the TTS cams will outperform all others in the vital roll-ons in the 1000 to 4000 RPM range.

TTS M8 cams are priced at $275.00. $358.00 for Twin Cams. In stock at RB Racing to pair up with our LSR exhausts and our RSR Air Fuel Ratio meters.

We have been asked by customers to provide LSR 2-1 exhaust systems for B1 / B2 / B3 heads originally found on EVO and 145" S&S Tribute engines and later T143 engines. Early B1/B2 four bolt flanges. Later B3 use two bolt flanges.We make both. The diagonal dimensions are the same two to four bolt patterns.

We have LSR 2-1, LSR 2-1 Pro Stock, LSR 2-1Pro Stock Spyder and LSR 2-1 Black Hole designs for these three S&S cylinder head variations.. Pictured above are our laser cut flanges and cnc machined hour glass shaped venturis that we heliarc to the B1 / B2 / B3 LSR 2-1 exhaust systems.

We have a specific fixture for the 126 S&S and T143 SAB2 / SAb3 Twin Cam Dresser systems as the billet cam cover is not OEM.

Milwaukee 8 Pro Stock Spyders in Production

People keep asking about RB Racing releasing LSR 2-1 exhaust systems for the new Harley Motor. Well, we are fixtured for them with a new muffler design that takes into account the increased compression and displacement. No matter what people say, this is an emissions-designed engine with a lot of compression, locked in place valve adjustment and camshafts that are simply going to give you limited gains for your hard earned money in just changing the exhaust. Every exhaust manufacturer wants your $$$. We don't.

Testing has shown cam changes need to be made along with a 2-1 exhaust to make any appreciable gains. Go ahead buy your $500.00 air cleaners and your $700.00 Monster Slip-Ons...keep the economy going. Won't do much except to help your park and talk routine.

Milwaukee 8 Spyder Mounting Instructions

Here we have a Milwaukee 8 LSR 2-1 Pro Stock Spyder 00-1396 being mounted up for final checks prior to being sent out a for a Dual Coat Black Ceramic finish.

There is a specific sequence for installing these and it generally takes two people, one of whom is there to help support the pipe and put in the two rear bag mount exhaust support bolts at the appropriate time.

Tools: 1/2" wrench or socket. Rubber Mallet. 3/8" open end wrench. 1/4 drive ratchet, 1/4 extension and 1/4 drive 3/8" six point deep socket. 5/16" nut driver or socket (shield clamps). 5/16" Allen socket on an extension for the floorboards. Split ring expander to mount the flanges and clips to the LSR venturis (exhaust port).

1. Plan on being careful with the exhaust so it does not get scratched up. Cloths placed appropriately on the bike and a drop cloth to lay the pipe down on the floor or motorcycle lift.

2. Remove the right floorboard. You will not reuse the two Allen Bolts.

3. Remove the stock exhaust and pry the oem exhaust gaskets out of the front and rear exhaust ports. You do not reuse the factory exhaust nuts, the mid pipe mount, or the left side (2 bolt) pipe support.

4. Install and fully tighten the transmission bracket, dowels and bolts. Use Blue Loctite on the three mounting bolts. Note that the front two dowels have a machined step to clear the transmission cover rubber gasket. Split lock washers under head of bolt.

3. Install the billet flanges and clips on the front and rear primary tubes. It's easier to slip the rear primary out of it's slip joint to do this.  Place the billet gaskets in the front and rear exhaust tube venturis.

4. We provide eight aircraft nuts for the 5/16" x 24 exhaust port studs... Four and four extra.

5. Place cloth to the inside of where the front pipe will end up. Slip the front pipe into the exhaust port (remove OEM gasket!) being careful not to drop the billet gasket.  Install one aircraft nut provided on the inside, leftmost, stud...about half-way, so the pipe can hang somewhat freely. Use with 3/8"open end wrench. Do not fully tighten this nut nor install the other nut at this time.

6. Place the rear pipe into the slip joint of the tail section. We put a thin coat of teflon paste inside of the exhausts two slip joints.

7. The rear OEM exhaust gasket must be pried from the port! Have the second person support the rear of the exhaust. Barely slip the font primary tube into it's slip joint and rotate the exhaust toward the rear exhaust port with the flange, clip and billet gasket in place. Work the rear pipe into the exhaust port...You will have to slowly seat the rear and front slips to do this. You can wiggle or gently tap with a rubber hammer the f/r pipes into their slip joints. We suggest you put a clean cloth over any rubber mallet face as they tend to get embedded with abrasive material.

8. Install, but not fully tighten, the two rear exhaust nuts on their studs.

9. With the pipe still somewhat loose lift it outward to install the two 5/16" x 18 bolts, aluminum spacer, lock washers and nuts to the transmission bracket. Do not tighten.

10. Have the second person lightly affix the two 5/16" x 18 x 5/8" bolts  (The OEM bolts are too short) and lock washers provided to the rear pipe support to hold the pipe up. Do not fully tighten these.

11. Now install the missing, rightmost,  front exhaust stud nut...Gently tighten, but not fully tighten, all four exhaust stud nuts.

12. Do not forget to reinstall the O2 sensors.

13. You now have two rearmost, two transmission bracket bolts, and four exhaust buts to tighten. As you do this you must have about  3/16" clearance between the exhaust and the transmission mounting bolts and the front brake lever. If you wrench down fully on one spot then go the the next etc. you can put things in tension. Sneak up on things before you fully tighten the eight points.

14. Reinstall the right floorboard with the spacers and new bolts provided ) 5/16" Allen.

15. The three loose heat shields are up to you to figure out. Be careful not to scratch things installing the hose clamps.

 LSR 2-1 Pro Stock Spyder Optional Sound Attenuation

All of our LSR Designs, except our LSR 2-1 Pro Stock Racing Systems, have welded in baffles without any packing material.

The reason is that we do not want any removeable baffles which have screws, bolts, rivets, or end caps that can come loose. We weld our baffles in place so, as we said in the late 1970s and early 1980's, that they don't come loose, take two bounces, and fly through a Mercedes windshield. We went through that drill 40 years ago. No removeable baffles.

All aftermarket exhaust manufacturers use an infinite variety of machined aluminum "butt plugs", as we call them, held in place by various fasteners. Sooner or later these get loose, fall out, or burn up in the case of carbon fiber. No OEMs i.e. Harley-Davidson, BMW, etc. want anything to get loose and fly out.

At RB Racing we design our welded in baffles for maximum flow and acceptable sound attenuation without packing so you can peg your built dresser at 135 mph with nothing holding you back...And you never have to re-pack them.

If you want a few decibels less we can, in the case of our Silver Ceramic, and Dual Coat Black Ceramic exhausts, insert a triple layer of stainless sound absorbing mat around our muffler core and then weld the baffle in place. This will knock a few decibels off the bark. We can do this for our 2-1 chrome systems but the baffle is removeable as it cannot be chromed.

The newer Milwaukee 8's have higher compression, more or less like a built engine with a 10.5:1 compression ratio piston in earlier models.  So, if you want a bit less noise on your bagger, opt for stainless packing material. It will not burn up like fiberglass and will stay there for a very long time. It has zero effect on horsepower.

This option is $60.00. Specify at time of order.

Scott had a back surgery (successful) and is healing. 00-1396 in Dual Coat Black Ceramic.

The Milwaukee-8 is a taller, heavier engine with the O2 sensors moved upstream, closer to where they should have been. Earlier LSR 2-1 designs will not fit this motor. We supply a different saddlebag mount system for our under the bag designs like the Pro Stock Spyder and Black Hole. All systems also have a three point laser-cut mount off of the transmission.

Customer writes: " I wanted to let you know that the Improvement on my Bike with your pipe is so substantial I am still at a loss for words to describe it.  We put it on while I was visiting my family for the holidays, So I have only had it on for the last two weeks, but I must say that this pipe is probably the best modification I have made to the bike.  It allows my bike to really open up right off the line and carry all they way through the top end.  The power that I have now is something I didn't know was available with everything that was done to my bike. I have the Stage 4 114" kit on the bike and your pipe really let me open it up to a new level.  When I am asked by my friends the only response I can give them is that I will NEVER have another pipe on any motorcycle I own again.

It came off the dyno with 119 HP and 120 Torque, the young man that ran the dyno did a great job, but I think he left some ponies in the stall, it runs up to 6300 RPM very nicely with lots of pull.

Milwaukee 8 Exhausts: 12mm and 18mm O2 Sensor Ports Standard

All LSR 2-1 Milwaukee 8 Exhausts come standard with both 12mm and 18mm O2 ports. This gives customers the choice to run either the OEM 12mm or 18mm O2 ports (or both with our RSR Air Dual Fuel Ratio Gauges) and tune with various narrowband or wideband options on the market. We also offer Dual O2 Wideband Gauges.

If you are running a Tuner that disconnects the 12mm or 18mm Oxygen Sensors with "O2 Optimizers", putting your bike into Full-Time Open Loop, then you should order our RSR Dual Air Fuel Ratio Gauge.

When you order the Gauge, for real-time, as you ride, monitoring for tuning purposes, we provide you the specialized harness plugs and wiring to connect your OEM O2 Sensors to our RSR Dual Air Fuel Ratio Gauge. It's the proven way to perfect your fueling.

Dual RSR Air Fuel Ratio Gauge: Late Model (12mm) O2 Sensors (Open Loop Only)

We provide the plugs, wiring and hardware to splice the 12mm Delphi Sensors to our RSR Dual Air Fuel Ratio Gauge.  It is the only method to monitor both front and rear cylinders of your bike as you ride. Real world observations to perfect your tune in Open Loop. Better than a dyno which tends to overheat your motor quickly with differing loads in the real world and things like the air cleaner picking up elevated temperatures, and dyno exhaust emissions skewing your tune.

Indian Chief

The Indian Chief is a "from the ground up" interpretation of the classical V-Twin, kept alive for over 100 years by Harley-Davidson, the sole survivor. In 111 or 116 cubic inch formats it's short on horsepower and long on clean sheet engineering. Indians are here to stay this time around after several aborted attempts to revive the marque.

Beautiful paint and chrome and true "Indian Heritage" styling it's a more modern interpretation of the classical V-Twin...This time around with three camshafts and some pushrods as straight as an Indian's arrow .

The OEM exhaust has little in the way of performance tuning. We've got that covered with a pure merge collector LSR 2-1 design.

Prices are on our Part Number Price Page. We build to order. Payment at time of shipment. Dual Coat Black Ceramic or Silver Ceramic with a choice of black or chrome heat shields.

Softail Spyder

95" 5000 Miles later

Customer writes:" Here is a photo of my 2001 Heritage Softail with your (00-1371) Pro Stock Spyder 1 ¾, C Style with 3 shields. The bike is a 95 CID, with SE 204 cams, Branch O’Keefe PT heads, one tooth added to the tranny sprocket then tuned with TTS Mastertune. I kept the torque and horsepower events in the low to mid RPM range and settled on a compression ratio below 9.8 because I ride 100 miles every day on open country roads using 91-octane pump gas. I have taken your advice on several products and they have all worked very well for me but I believe the Pro Stock Spyder is what pulled everything together to achieve impressive gains in performance and produce a far better sound. I have 67,000 miles on the bike including the last 5,000 with your pipes so I can tell you with confidence the changes in performance due to the Pro Stock Spyder were very evident particularly when hitting it hard on open road.
 
As always, the fit and finish was perfect, the slip joint, billet gaskets, and special nuts made the system easy to install, and it looks way better than the other exhausts I have seen. I am very satisfied that I bought your exhaust system and I recommend them to anyone who values performance and good looks.
 
Thank you for building a truly excellent American Made product. Ray"

Many Miles Later

Customer writes: "Just so you know, I really like the RB Black Hole Spider exhaust that was installed on by bike at the dealership at about 3K mi. The pipe has about 105,000 miles on it now and as you can tell by the pictures it looks as good as the day it was installed.  The shields look good after a buffing job, even though the rear one had oil dripping on it for the entire time it was on with the other intake that was on the bike.  Word of caution, the Screaming Eagle Ventilator intake from HD is crap, nothing I tired would stop the flow into the air cleaner element and then out the bottom onto the pipe. The final fix was a new intake, (not HD).

I put a new 2011 stock 103 motor in the bike in April and while it was down I sent the Spider to an outfit in WI (http://www.classiccoatings.com/ceramic.html#satin) for ceramic coating inside and out and it came out great.  The heat reduction really surprised me but I can't really attribute it all to the coating because it's not the same motor, I can't be positive how much it really helped, I just know it doesn't seem as hot now and the gauge doesn't go as crazy in stop and go traffic.

Your product quality and performance far surpasses anything else on the market and cost recovery, if used for any length of time, makes it a bargain.  This is my second LSR and when I sold my '02 Ultra it had 105K on it and the Black Hole system had over 50K on that bike and I bought the LSR system used!

Anyway; you produce a fine American made product and I commend you and those that work with and for you.
Now if I could find a way to get one of those Orca motors stuck in that place under my seat I could keep those pesky goldwings at bay.
A satisfied customer,

My apologies for waiting so long to email you some pictures of my 2012 Road Glide with your AWESOME 2-1 Pro Stock Spyder Pipe. Man RB RACING ROCKS! This pipe has given my bike so much performance, especially on the bottom end. I still had factory exhuast with some crappy Screamin' Eagle slip-ons, I installed the S&S Stump Puller Cams (551), S&S heavy breather air cleaner, then I flashed the ECU with the TTS Matertune and ran it that way till I got my RB Racing Pipe. I put the 2-1 Pro Stock Spyder Pipe on, ran the TTS Mastertune V-Tune a couple of times with my little fox on the back up and over the point on I-15 here in Utah a couple of times. Then went for a ride by myself and Holy Shit what a difference. Havent put on a dyno and probably won't becuase of the great job V-Tune does. But I can tell by my Butt Dyno, I've got some substantial horse power increases and a ton of torque compared on a before and after comparison. I've had it on a couple of loong cruises riding 2 up, and it just pulls!I've gotten a lot of compliments for looks and a ton of compliments for sound! Really happy with your hand made by Americans in AMERICA products!
 
Thanks for the awesome 2-1 Pro Stock Spyder Pipe, Mike."

Bigger engines, more compression, radical cams and the never ending search for power and individuality have exponentially raised decibel levels and eyebrows. The men in Blue have their orders and are now listening for you. Reality TV shows are edited and condensed for consumption. Strife, tension and open exhausts are good entertainment. Nothing has to actually have to work beyond the last commercial. Hit the road with your dream and collide with reality. You can't park and talk all your life...or maybe you can.

Performance and a mild dose of acceptability can coexist but it requires original thinking. RB Racing has married their race winning LSR 2-1 Pro Stock exhausts and their silent running LSR 2-1 Black Hole systems to engineer a solution to kicking ass in a society that looks askance at the outlaw.

Again I compliment you on your product, I have a little over 72,000 miles on Black Hole Spyder pipe and the only thing that is wrong is I can't seem to keep my boot off of the shields.

I have use other 2 into 1 systems and none have lasted over 55K miles, the Thunder Header welds fell apart and the mount broke (yep, broke!) at 55K and the damn Screaming Eagle burned through at 35K. I'm dealing with health problems now and do not get to ride as much as I would like but I really don't want to have to work on a bike every time I take it out of the county.

Our Ohio Patriot Guard Riders escorted the Marine Aviation Memorial Tower from Cincinnati, OH to Pensacola, FL last week and I came right back home.  I didn't even ride down the coast or through any of the historic sites in Georgia and Virginia, this getting old isn't for the weak!  Old injuries just keep reminding me that I should have had more respect for my body as a younger man.

Anyway I have great respect for your operation and products, if I ever see my way clear to upgrade to a monster engine it will be a turbo Orca for touring and distance riding.  You have copies of my bike when I first put the header on it, the only things I have changed are the wheels and painted a few of the exposed black plastic parts and used smoked lenses on the lights.  It draws attention almost everywhere we ride and the Road Glide people especially like it.  They almost all ask about the pipe and a few of my riding buddies have purchased them they all have positive comments about the craftsmanship and and performance of your products.

Thank you again, John."

You will also need our billet gaskets, billet flanges and snap rings, heat shields, and an extra set of our special exhaust stud nuts. 135 claimed hp is nice but the noise gets old...unless you only want to run your sled on a dyno. In the real world the man is waiting for you.

As all the mythical lemmings head off the cliff we might remind them that a S&S SA B2 126" engine is rated at 154 hp and John O'Keefe at Branch O'Keefe has been working SA B2 heads for big inch Sportsters, S&S 124" motors and getting 166 to 200 hp depending on compression. Of course you could get one of our turbos but the extra 100 to 200 hp might be too much power for you.

Bye bye men in blue

The highway is for gamblers, better use your sense. The blacktop, too, is moving under you. Yonder stands the man in blue.. all ears and waiting for you. All your straight pipe friends are coming through...music for the man in blue. Free tickets for the courtroom door... Twist the grip and start anew, the man won't be stopping you. Spyders pass straight on through. Your friends will meet the man in blue, but the road ahead calls out for you. And it's all over now for the men in blue.

Black Hole technology. Pro Stock power.

Trap noise, not power

Black Hole technology traps noise but offers little restriction to exhaust flow. Spin your web of deceit and go quicker, faster, with less wear and tear on your ears and your wallet. Noise is still equated with power but we are striking a median between our silent running LSR 2-1 Black Hole systems and our pure racing, championship winning LSR 2-1 Pro Stock systems.

As engine sizes grow to 95/103/110/113/124 etc. and you add compression and cams the man is simply waiting for you. True Duals, Pro Pipes, Thunderheaders, Big Radius show pipes are all loud, straight though, designs. All are way past 100 Db. Marketing 101 meets the road. 300 series tires with matching love handles, open, rock-catching belt drives and billet grips that were designed for that cold winter morning. And it looked so cool on TV.

Fast and torque remain the constant where the rubber meets the road. Roll out to pass that semi or peg the throttle while leading the pack. Some things don't change. We try to keep it that way. Artistic expression is more fun when it works. High heels and a killer omelette.

2007...Bye Bye Duals

Customer writes: "I just wanted you guys to know, you have one awesome product.  I "had" Rinehart slip ons on the factory headpipe.  The problems with reversion are certainly nothing to laugh at.  I have wide band O2 sensors and you could see the false air on the back cylinder at low throttle openings.  Scavenging sucked.  I got all of the problems with true duals with none of the benefits.  After installing your great looking product, the pull from down low is awesome, midrange is great with no fall off (like before) up to redline.  In a couple of weeks I'll forward the dyno pulls with the prior setup vs. the new (yours).  Reasonably quiet during cruise (sounds great with a bit of Pro-Stock burble) and sounds Kick Ass when you get on it.  My main problem is the shitty gas mileage cause I can't keep my hand out of it.  Again, thanks for a great product.

00-1367 1 3/4" LSR 2-1 Pro Stock Spyder. You should end up getting 40+ mpg...those are different issues...Just remember running 13.2: 1 instead of 14.7:1 throws 11% more fuel out the pipe. There's a reason why things are closed loop to 14.7:1

Sleds and The Man

Customer writes: "Dear RB Racing. I finally got around to sending the pic you requested! I have to say that this is the best system I have used to date, and I won't be changing it any time soon. The flow characteristics of the pipe really make it wind out quickly, and the heating/pinging issue I was experiencing prior to installing this pipe are gone. The sound is how I like it, and it doesn't seem to attract the attention of the law as long you are judicious with the use of the throttle. I'd buy this exhaust again, without question! Thanks for the great service and a great product! Doug and Deborah".

On the Road

Customer writes: "To the RB Racing crew: I wanted to thank you for providing the outstanding 00-1367 Chrome LSR 2-1 Pro Stock Spyder for use on my 2004 Ultra Classic.  The workmanship of the pipe is amazing and the fitment was great also.  My bike has a 95 inch Stage 4 big bore engine including SE high compression pistons, heads, and 257 cams.  Originally, I used the SE slip-ons that seemed to work well; but, I was not satisfied with the torque curve.  The 257 cams normally started pulling hard around 3000 RPM with the SE slip-on mufflers. 

After installing the LSR 2-1 Pro Stock Spyder and working closely with an outstanding dyno tune master, John Helvey, the engine started pulling hard around 2500 RPM and continued through normal operating RPM range.  The engine also runs smoother and has excellent fuel economy.  While the pipes represent a significant financial investment, they are worth every dollar!  I attached a picture of my bike with the 2-1 Pro Stock Spyder pipes installed. My only negative comment is I would have appreciated a better powder coated rear mounting bracket since the one I received had bare metal exposed in a couple of places.

Now on to the next project.  I would be interested in information on your turbo systems.  I would appreciate your opinion on whether it is possible to fit a turbo on my Ultra Classic and maintain reliable street touring performance.  I am interested in the turbo because there are times when I want to put the hammer down while riding with my buddies and want to make sure NO ONE will out run me!  I hope this does not appear to be a strange request from a touring bike rider; but, I still have deep roots to back in the day when I would run a bike at the drag strip.  Finally, will a HD SE big bore engine require significant upgrades to the lower end and drive train to withstand periodic turbo enhanced accelerations?  I am running a competition clutch with medium spring tension. Thanks again for making your outstanding products available to the everyday man! Jim"

Reply: We've been doing turbos for a long, long, time and know the realities of the engineering challenges to make them long term viable propositions. We'll be releasing very sophisticated systems for the FL series when our Bonneville racing slows down and other turbo projects finish long term testing. Everyone wants more...we always want more. Anything under 200hp is sort of boring.

2008 103" LSR 2-1 Pro Stock Spyder

Pictured: 00-1367 LSR 2-1 Pro Stock Spyder, SS Titanium finish, 1 3/4" with four chrome heat shields on a 103" 2008 FLH Twin Cam. Engine has Branch O'Keefe cylinder heads. This bike was tested with the 103 then converted to a 110" and retested. We revised the muffling structure a bit to get more power and not appreciably increase the sound. The criteria was that that it could be loud at W.O.T. but it had to be acceptably quiet at cruise so it would not bother fellow riders and so that the stereo/radio could be heard. Leaving black stips of rubber and dyno testing showed the pipe worked fantastically well with the hot rodded 110.

We changed the secondary tube length, adding 3" for a bit more low end and made internal changes to increase the internal bypass by 50%.

When were happy with the 110" results with 10.5:1 compression and 58mm throttle body, larger injectors, and cnc ported 2.125" inlets, we notified several existing customers and upgraded their systems at no charge. These pipes go on anything from 68 hp TC96 engines to 120+ hp big bores. We then retested the system on a stock 96" engine, testing for sound and power and got excellent results. It's simpler for us to not tailor the muffling structure to each engine size as people keep upgrading their bikes.

John O'Keefe of Branch O'Keefe has 103" kits for late model Twin Cam engines. Stock 103" engines from Harley make maybe 80 horsepower. This doesn't cut it with an 800 lb sled. Branch Specifications: Larger inlet and exhaust valves; .060" decked cylinder head; compression releases; new valve guides; racing valve springs; flowed inlet and exhaust ports; forged lightweight pistons contoured to match quench style combustion chamber; and BP-600 Branch camshafts. Not a bad idea to get a matched, proven, combination.

John does all our race stuff and has since 1977.

Walz Hardcore Frame

We get a few of these in our shop...Usually they are really long term projects i.e. the people buy the frame and wheels then shuttle from shop to shop trying to get things to fit and the bike never seems to get to completion. We made up a 2" LSR 2-1 Pro Stock Spyder for this one that is headed for Black Ceramic coating. As there were no frame mounts we had to machine, weld and fabricate one made out of 1/4" steel plate that hangs from the 19mm swingarm pivot bolt.

Customer writes: "I installed the pipe the day I brought the bike home. That had to be the easiest pipe to install. Took no time at all. Fit like a glove. Your wife asked for pictures of the bike. Thanks again for the pipe. I took the bike out for its first ride in many years and sounded as good as it ran. Tons of power, I'm sure it doesn't hurt having the correct pipe on it to make all that power. John"

If any of you Walz guys want one they are $1,500.00 in Black Ceramic without the heat shields or $1,350.00 in chrome without the heat shields. They chew up days of shop time...All custom fabricated with compound bends. Part Number is 00-1383.... 2" LSR 2-1 Pro Stock Spyder for a Walz Hardcore frame. In this case with a R&R 127" motor. Everything on this bike was non-standard. Even the stud spacing was non-oem. It's a runner...finally.

2008 110 CVO LSR 2-1 Pro Stock Spyder

Customer Writes: "Wanted to send you pix of my new pipe after installation. Haven’t had a chance to dial it in yet, too cold for much riding!  However I have done some.  Fit and finish were wonderful. Already gotten several comments on it’s appearance.  This system picked up the power tremendously!  Really woke up all 110 CI’s.  Bike runs smoother, and is very responsive. Once it warms up here to the point I can actually get the engine warmed, amazing how cool they run when it’s only 11 degrees, I’ll send you more info.  Till then, thanks."

Stock 103

Customer writes: "There is a picture attached of the bike after the installation and it is very telling of the change. The installation dropped the weight of the exhaust system a few pounds by doing away with the left side muffler and crossover pipe and it achieved what I wanted to do by giving me better access to the Harley Davidson center stand that I had installed when I bought the bike. The system also shortened the exhaust tail section by ending at the edge of the saddle bag rather than protruding to the end of the fender, giving more curb clearance in length and height. The sound is great and it doesn’t attract the attention of the law dogs like most of the after market systems do. It looks like it is a full muffled system because of the size and shape of the can and shields and unless I’m into it hard it is grudgingly acceptable to the highway patrol (road nazis as our county sheriff enjoys calling them).

And to top it all off, it looks marvelous, pronounced MAHHHVULUS! (you know, the Billy Crystal line). I have had some of my gear-head buddies wanting to know where I got it and what it cost, kinda like having a steak sandwich at hotdog stand you know what I mean? Anyway, I'm pleased with the outcome and service you folks provide. I know I bothered the shit out of you to get this thing but you put up with it and made me happy with my big black bike again, thanks. I will send better pictures in digital format on a cd as soon as I get around to making one, I'll make a little video with sound just like the the big kids do so in case you want to use any of it as a satisfied customer statement you will have it. Yours, John "

$1,000.00 for Saddle Bags...5 Finger Discount $0.00

FLTRI Road Glides are a big theft item around here...their bags even more so. After one of our employees lost a set of bags off his 2008 110" Road Glide, and had to buy another set of bags, we made up a few simple sets of Left/Right brackets that secure the bags to the rear mount with a couple of stainless steel button head screws and self-locking nuts. Unless someone has a 3/16" Allen and a 1/2" wrench the bags aren't going anywhere. Around here they will steal the bags even if the outer lock is set...they just pry them open.

The pictures show the brackets on our shop 2004 FLTRI we use for testing exhaust systems. The bike is going to be converted to a 126" ORCA Turbo motor with 350 horsepower.

If you want a set of L/R brackets they are $15.00 in raw metal. Drill four 5/16" holes and you're done. Undo the bolt to the bag and the bracket can stay on the rear bag mount. Paint them or chrome them yourself. Not a big deal around here. We just don't need any $1,000.00 surprises.

Hand Made Pro Stock Merge Collector

From exhaust port to the collector area this is a pure LSR 2-1 Pro Stock exhaust system for the highest velocity and peak scavenging at the exhaust valve. We mate this to a special version of our low restriction, noise-cancelling LSR 2-1 Black Hole technology. Not as quiet as a LSR 2-1 Black Hole system but a pure racing system quiet enough to get you by the man.

Softail LSR 2-1 Pro Stock Spyder

00-1345 LSR 2-1 Pro Stock Spyder, 2" Style C. This system headed for a 124" S&S motor. Bigger motors like these can use 2" primary tubes. It's all about the timing of the pulses to the merge collector.

Nightmare After X-Mas

TV, Jesse James, Orange County Choppers, biker build-offs, master builders. Art is cool but when the cold winds of reality blow you get back in your pickup truck. No way to make a fashion statement quiet enough to avoid tickets and get you where you want to go. Great for the short putt to the bar or HOG meeting where you can bask in the glow of your "I saw it on the Discovery Channel and now I have one". We like art and sculpture and Dali would approve of the drooping exhausts but that's not why we build things. Noise, loss of torque, tickets...well, we make pure race pipes and will give you back your torque if you'll take take the the other two with it.

LSR 2-1 Pro Stock Spyder systems offer an alternative. Power and performance with an acceptable amount of noise. We try to factor in art as we are violently opposed to ugly. Beauty as they say is in the eye of the beholder.

If you want to make power on a multi-cylinder engine you have to use a collector system. Whether it's a V-Twin or a V-8 it's the same, and no less an authority than the famed engine builder Smokey Yunick will tell you that. Not using free exhaust energy to help your engine breathe is downright criminal. No matter what the conventional wisdom is, staggered duals on a Harley will not make more power.

You simply cannot escape the fact that a properly designed 2-1 will give you more useable torque where you need it, in the 2000 to 4000 rpm range, which means less downshifts and less rpm to get the job done. A set of short staggered duals at peak rpm can be made to produce good power but they will be dead on their ass until they get there, whereas an engine developed around an LSR 2-1 exhaust can be made to perform from the bottom up with no dips in the torque band!

Torque and Ruby Slippers

People get pissed at us when they ask for "numbers". We always tell them we "don't know" because after nearly 33 years of tuning and racing and designing we have seen too much and done too much to give any placebo answer. In fact, it always depends on the bike and the tuner. No two bikes are alike. Maybe your bike was built on a Monday and they left a coke bottle in the gas tank (old Detroit wive's tale)...Some bikes are faster than others. Everyone believes their bike is "faster". It depends on the tuner and, these days, the bikes are more complicated. People change from chain to gear drives. They put on different cylinder heads. They switch cams. They add on tuning twiddle boxes. They tune, or the "shop" tunes. They "dyno" the bike...maybe even somebody rides the bike with instrumentation like our RSR Air Fuel Ratio Gauge.

People call us up then hang up when we tell them we don't know what their "gains" will be. We don't publish self-serving charts. We just take all the experience we have and build the best parts we can. People end up happy who buy the parts because they are well made and are designed to perform. We make different tube diameters and offer a wide range of systems for any particular bike so you will maximize your potential. There is no "One Size Fits All" at RB Racing.

People who don't buy the parts because we won't coddle them with assurances go elsewhere where Aunt Em will tuck them in and tell them what they want to hear.

 LSR stands for Land Speed Record and that means only one place...The Bonneville Salt Flats, the Great White Dyno. We have the only gas powered street legal bikes over 200 mph and we're damn proud of it. RB Racing doesn't race typewriters, we race motorcycles and when someone says they get a 70% gain from their system, ask them for their 200mph Bonneville Records or any records for that matter. Hell, if we raced typewriters it sure would be a lot easier, not to mention cheaper.

The technology we use with our turbos equally applies to our exhaust systems. Turbos don't make more power with excessive exhaust backpressure and normally aspirated exhausts don't like restrictive mufflers either. These are just antiquated 100 year old air compressors and they need all the help they can get.

Our competitors must think you won't notice that they neck their 1 3/4" to 2 1/4" pipes down to as small as 1 1/2" to mate them to your exhaust ports. RB Racing's Turbo Venturies are expertly heliarced to each primary tube eliminating any internal obstuctions and insuring the maximum flow from each exhaust port. RB Racing won't build phony performance pipes...We sure as hell won't ask you to port your heads, put in bigger valves and a high performance camshaft then stick a bunch of stainless steel discs or machined aluminum butt plugs in the pipe to restrict the flow! And we damn sure won't put some silly "1950-ish" reverse megaphone pipe with internal flat plates, baffles and air foils to screw up your performance. Our pipes make anywhere from 6 to 18HP over these stupid designs. From the Turbo-Venturies to the exit of the pipe our pipes outflow all other pipes on the market. Pictured above is a 00-1261 LSR Black Hole 2-1 for a Dyna TC88, Style C, 1 3/4" shown without heat shields.

For those of you who bought the slip in "torque cones"....Throw them in the trash.

Our CNC machined Turbo Venturis are not compatible with the "bowl-shaped" late model OEM exhaust port gaskets and require early style "flat" gaskets for the LSR Exhaust Systems to both fit and seal properly. The narrow machined flat face of the Turbo Venturi must seat against a flat surface, not the bowl-shaped late model gaskets. Using the LSR Exhausts in combination with the wrong gasket will cause misalignment, inability to tighten the provided close tolerance aircraft nuts, and will force the bowl-shaped gasket into the exhaust port. The correct woven style gaskets to use are: Harley OEM 65324-83 or Drag Specialties DS 174742.

Customers have asked us to include our billet gaskets with each LSR exhaust system as it is a hassle to search for the correct flat woven, early style gaskets and they cost the same as our superior billet gaskets.

Mandatory for a nominal charge of $9.95 are a pair of our LSR CNC machined gaskets which mate perfectly with our Turbo Venturies. These are proven in over 16 years of use on our race and turbo applications...the only gaskets that will stay in a turbo bike for 25,000 miles! These gaskets prevent any gasket "creep" into the exhaust flow and are one more thing that will give you "an edge" on the competition. We always wondered why people would port their heads, put in bigger valves and then squish the gaskets into their exhaust ports. We bet you never paid attention to what was going inside your exhaust ports for one very simple reason...you can't see what's going on in there once the pipe is tightened! The LSR CNC machined gaskets also insure perfect alignment of the exhaust system. Most fitment and alignment problems are traced to using either the wrong type of gasket or using old gaskets that have taken a "set". We've always used these on our race applications and it's time everyone who's concerned about performance should do the same.

Chrome, Black Ceramic, or Silver Ceramic: All chrome is full automotive grade duplex nickel, triple plate; Black Ceramic finishes have a semi-gloss black look. Silver Ceramic finishes have a polished surface finish. Black or Silver are fully polished as if they were to be chromed to remove any surface defects, then are blasted, and finally ceramic coated.

Ceramic finishes hold the heat in the exhaust better than does chrome. Chrome has the hardest surface finish. Ceramics do not change color. Ceramics can scuff or marr if hard, sharp objects scratch them. Heat shields for the primary tubes and collector area are recommended for all applications to prevent any contact with the pipe's surface.
