LSR 2-1 Sportster
New 2004-2008 Sporster LSR 2-1's
Rubber Duckies hit the street. FXR's reincarnated in a smaller package. We have a range of new exhausts for the 2004 and up rubber mounted Sportsters. Harley changed the exhaust flanges so you'll need to pick up a set of older flanges and clips for the LSR 2-1 Venturis. 00-1270 shown on 2008 Nightster in ceramic black.

Customer writes: "These pipes are awesome! They look good, sound great, perform very well and they lightened my bike. I can't go anywhere without getting compliments everyone wants to know where I got them. They were well worth the wait!" 00-1271 in Ceramic Black.
45 years ago a Sportster was something to be feared. They were loud, fast, didn't stop, and were about as macho as you could get. Death struggles between Triumphs and Harleys for track supremacy while the country was meeting the nicest people on a Honda Cub. Year after year the "XR" has formed the basis of every form of Harley racing from Drag Racing to Bonneville and famous road racers like Lucifer's Hammer and Cal Rayborn. Now Rhonda carries the colors.

Sportsters, or basic Sporteter designs, have ruled the drag strips for more than 50 years. Struts, lowered, chain drive, spokes, a sticky rear tire and bare to the bone...four cams and 7000 rpm in a light chassis that is now rubber-mounted so you don't wear out the porcelain on your teeth.

The long wait was well worth it, when I picked the exhaust up it was like winning an award cause the thing was sooo damn good looking.. So for those of you waiting, the pay off is kick ass. Also we did a dumb I mean drum dyno at Dyno Daves in Canoga Park with a gain of 7hp! Throttle response is tight, sound is great kind of like "potato potato potato" hahaha. N E ways you guys kick ass!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Thankz from the big S.F.V.! JW"

Customer writes: "Attached are photos of my 2007 XL883R Sportster with the LSR 2-1 (00-1270) exhaust in chrome. The pipe looks great and has a terrific sound. Bergen County H-D/Buell in Rochelle Park, NJ dyno tuned the bike. The peak horsepower went up to nearly 58 from 47 (a 23% increase) and peak torque to 54 from 48. On the road it really takes off from 4000 rpm right up to 6000 and above. Please tell everyone thank you for a job well done. I will be strongly recommending RB Racing pipes to people I meet. I'm also going to post these photos on xlforum.net and credit RB Racing (xlforum.net is where I first learned about your exhausts). Best regards, Kevin"
Baby FXR's. They are nice bikes. They actually handle and stop. Customer put some compliance into the rear suspension instead of the oem fish-oil units.
New Dual O2 Meters
For EFi sequential injection our new RSR Dual Air Fuel Gauge displays the fuel mixture in both the front and rear cylinders separately. The gauge is housed in a hard anodized round enclosure in a standard 2" format with a 2.250" bezel, center back mount, with a 5/16" x 18 stainless socket head cap screw. The gauge will show fuel ratios from 17:1 to 12.0:1 (or richer). The gauge is visible in daylight and automatically dims for nighttime operation.
Scale is, left to right, lean to rich: three greens, three yellows, two orange and two red l.e.d.s.
The white arrow indicates the maximum power mixture, the second orange light, which is 13.2:1. Transitory enrichments should not, if the engine is warm (>200F Oil temp), go past the first red light. Readings at the far right side of the scale, the second red light, are simply too rich. In closed loop operation the lights will cycle back and forth indicating the ecu is correcting to Stoichiometry or 14.7:1. Shown mounted on a 2008 Sportster.
It is simply the best way to evaluate the tune of your motorcycle and saves valuable dyno time. Mounted permanently. Waterproof.
Compatible with dual OEM narrowband sensors. No soldering required Can be supplied with new high temperature Bosch narrowband sensors. Far right photo shows gauge in dim light conditions at maximum power setting.
Three degrees of freedom. Supplied with longer bolts for triple clamp or headlight mounting. Stainless bolts. Or get creative and roll your own. Could be as simple as one hole or a flat strap with two holes. If you want one of these they are $24.95. Part Number 06-1024. For single or dual O2 meters.
Single O2 meter for Carb models
For the past 20 years we have been putting O-Sensor ports in the front primary tube. It is the only way to set your carburetion for optimum performance and economy. Our RSR Air Fuel Ratio gauges are completely waterproof and Harley proof. Billet construction and dead accurate. Saves dyno expense. If you just can't stay away from Dynos then tune with this first in the real world, then go to the dyno.
Do Not Use OEM Gaskets
LSR 2-1 Exhaust Systems must use our CNC Machined Billet Gaskets (part number 00-1000) and our close tolerance aircraft exhaust nuts (part number 00-1001). The above OEM woven gasket will not work with our machined Turbo Venturis. Four special aircraft exhaust nuts come with the system but you must order four extra ones for $3.00 as they are easily dropped and the OEM 5/16" x 24 hex nuts will not "turn" on our machined Turbo Venturis.
We also offer machined from billet exhaust flanges. If you have a 2004 or later bike it will probably have the thicker exhaust flanges which are not compatible with our Turbo Venturis. Early style OEM Evo chrome die cast flanges and clips or our billet parts are called for. Our Billet Flanges and clips are $29.95 per set and are stronger than any oem part.
We have had several instances where people encounter "difficulties". Invariably, it is traced to someone not using our billet gaskets. The billet gaskets insure proper fit of the LSR 2-1 system and are designed to work with our Turbo Venturis to increase exhaust flow.
New SS Titanium Finish
In our continuing effort to offer you the best product we have a new SS Titanium finish that we have been testing for a year. We now have four finishes to choose from: Chrome, Silver Ceramic, Black Ceramic, and SS Titanium Ceramic.
Chrome is a no-brainer. It's a shiny, reflective, hard surface that can be covered by heat shields and is resistant to scratching. Black is the finish when you want black...It's that simple. Silver Ceramic is a popular coating that is well known to be durable and to hold the heat in the pipe.
The new SS Titanium finish is a dark semi-gloss metallic grey that will not show dirt, stains, or marks as easily as do the other ceramic finishes. It is the lowest maintenance of the "coatings". Sportster Pro Stock Challenge shown.
These exhausts are available in Chrome, Silver Ceramic, SS Titanium or Black Ceramic finishes.
Note: Ceramic finishes on LSR Exhaust systems are taken to the coaters every three weeks. Payment for all ceramic finishes is made at the time we delivery the parts to the coater as at that point the process is irreversible and very expensive. Batches from the coaters are finished every two to three weeks. In short, if you order a ceramic finish i.e. Black, Silver, or SS Titanium payment is effected before shipment and is non-refundable.

04 and later Flanges
The Harley part numbers for these flanges (above) and clips are: 65328-83 (exhaust ring clamp) and 65325-83A (retaining ring). RB Racing makes Billet Steel Machined Chrome Flanges with spring clips that are far sronger than the die cast OEM items. Our part part number is 00-1002, $29.95 for a set of the flanges and clips.
2004 and later Sportsters need to order these flanges or their equivalent at your Harley shop as the oem flanges are too thick for our Turbo Venturis.
06' Dual O2 Sensor Systems / RSR Air Fuel Gauges
Since we have been doing closed loop fuel injection systems for Harleys for more than 15 years and have been putting O-Sensor Ports in our exhausts for the same amount of time, we have dual O2 ports for the 06 models for our full range of exhausts. Our RSR Air Fuel Ratio Gauge is the best investment you can make for these.
All LSR 2-1 exhausts can be ordered with two O2 ports. Actually O2 sensors are a really neat item. We should know, as we have a lot of experience with them. Tuning strategies are different and there are a lot of things that can go awry if you forget about temperatures, pressures etc.
Pretty soon Harleys will all be watercooled then you really won't be able to tell the difference between Milwaukee and Hammatsu. "The Man" will be sniffing your butt and planting microchips and gps modules up your ass so they can mail you a speeding ticket and keep track of your movements. They already have data recorders on your car so they know what you were doing when the biggie happened. Brave new world.

Customer writes: "First, I have had your LSR 2-1 C w/Turnout on my 98 FLSTS for about 4 years and 32,000 miles. It looks great, sounds great, and of course, performs great.
Second, the mechanic that works on my bike also drag races a Shovelhead powered FL. He only ran Thunderheader until he rode my bike and did some research. Steve had you guys make him a 2-1 and set new records in his class.
Third, my brother-n-law has a '05 EFI Road King. He was just dying to put some Rinehart true duals on it. I talked him into waiting until he looked at and listened to a lot of RKs before buying. During the year he did this I kept asking what he wanted out of the new exhaust. Finally, he admitted sound and performance. He kept saying I love the sound of your bike and it is fast as hell. So, I suggested the LSR 2-1 C Slash Cut longer pipe. We installed your exhaust, a PCIII usb, and a K&N filter with stock a/c cover and changed the backing plate. His road king has torque and runs like a scalded dog. We both can out run 95" kits installed at the HD dealers.
I provided the background to say this. My B'law took his RK to the HD dealer for the 15k maintenance service. The mechanics went nuts over the exhaust and what it does for the performance. They asked all kinds of questions. They had never heard of your firm or the exhausts. Now comes the kicker and it makes me a little sad (because I have enjoyed having an exhaust that out performs the crap the HD dealers sell). The mechanics conclusion. They are going to take off that HD exhaust crap (their words) and get RB Racing exhausts. Now the word will spread around Memphis and RB Racing exhausts will be everywhere.
It was good while it lasted - having the performance edge over others.
Your exhaust system has been great on my bike for 4 years and 32k miles. Thanks for a great product. I can't imagine having any other brand of exhaust!
PS. Sure wish you would make a LSR 2-1 for Victory Jackpot or 8 ball. The only reason I haven't purchased one in the last two years is because you said you would NOT make a Victory exhaust.
Later…Cliff"

Bonneville Proven 
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.
New Exhaust Tech Section
We have given a bit of an overview on the design of Harley Davidson exhaust systems for those who have questions about primary tube length, tube diameters, collector design and the pulsations and wave timing in a V-Twin engine. Heat is energy...use it to your advantage!
Here we can see on this LSR 2-1 Pro Stock Sportster exhaust how turns influence the build up of heat as well as the energy concentrated in the merge collector. We have to clear things like footpegs, master cylinders, highway pegs, brake pedals, air cleaners etc. in our search for power. Testing at Blue Springs Harley Davidson...James.

Jim Snyder set new speed records with his Sportster. We couldn't get him a Ceramic Black pipe in time so we sent an unfinished pipe so he could make his race. We shipped his Black LSR 2-1 Pipe a few days later. We love racing. It sure beats the hell out of parking and talking. Race bikes, even if they are street bikes always have a drama about them because they have stories to tell.

LSR 2-1's Bonneville,Dyno &Track Proven
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! If you don't believe this then why is it always that the top Pro Stock bikes, cars etc. end up running collectors systems? Damn right they work! If you don't think torque between shifts or when you roll the throttle on, then buy those long sewer pipes or some short curly drag pipes you saw on the Discovery Channel.

New Cloisonne Tags
Like in the adage "The relentless search for perfection" we have upgraded the logos we put on our LSR Exhaust Systems. Previous tags were stamped and formed aluminum with silkscreened details. The new cloisonne tags are a precision die struck brass, nickel plated, with powdered glass fired in an oven then polished to a jewelry finish.
These are direct replacements for our older tags and are available for US $20.00 via US Global Express (foreign) or Priority Mail (domestic US). They come with black headed rivets and are riveted in place with a light coat of high temperature silicone (Permatex 598B) behind the tag. LSR Tag on 00-1271 system shown above.
Baffling Alien Discs and Aluminum Butt Plugs
Our testing has shown that the Harley V-Twin is extremely sensitive to back pressure which is why 2-1's that use small or restrictive collectors don't breathe well, and why restrictive baffles shut the motor down. Disc type baffles are good for spark arrestors on dirt bikes but they have no place on a big inch V-Twin. You don't make power by adding restrictions to your exhaust system whether it's a bunch of stainless discs or some damn piece of aluminum billet machined into a Harley butt plug! Ever wonder why they had to put a hole up the center of the discs? Well, one reason was the discs are so damn restrictive you have to have several pounds of them to get enough flow through their waffle shaped passages. Good mufflers, but they have nothing to do with performance and they sure as hell do not create vacuum as has been claimed. When you get confused by all the bullshit simply ask the following question.." Do they run them in NASCAR or in Formula One?". Nope, they run straight pipe collector systems without any stupid discs or aluminum butt plugs.It's always funny how when the money is on the line, all the little things like discs, billet caps, anti-reversion flaps, reverse megaphones and other such nonsense somehow don't make the field.
Turbo Venturis
All RB Racing LSR Exhaust Systems feature our "new" (we've been quietly doing it since 1985!) CNC machined Turbo Venturis that actually "scavenge" to help your motor breathe. Machined from billet, these allow full 2" flow and eliminate the phony restrictions that other 1 3/4" to 2 1/4" pipes have at your exhaust port. We supply special close tolerance aircraft nuts for your exhaust studs because our machined venturis are too wide for a standard hex nut.
00-1271 in Ceramic Black shown above.
Our CNC machined Turbo Venturis are not compatible with the "bowl-shaped" late model OEM exhaust port gaskets or 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.
Mandatory for a nominal charge of $9.95 are a pair of our LSR CNC machined gaskets which mate perfectly with our Turbo Venturis. 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.
Nuts
All LSR 2 into 1 exhausts require special close tolerance aircraft nuts to bolt the LSR Turbo Venturis to the exhaust port. Standard 5/16" x 24 hex nuts will not fit. Each exhaust comes with the required four nuts. It is recommended that you order an extra set (4) of these nuts, part number 00-1001, when you order your exhaust.
STD Cylinder Heads
We make special flanges for STD heads that match the rectangular bolt pattern that STD machines. If you order a RB Racing LSR 2-1 Exhaust you can order these flanges which have been designed to fit our standard turbo venturis. RB Racing Part Number 00-1003. Sold per pair $29.95. When you order a RB Racing LSR 2-1 Exhaust system we either polish and chrome these or bead blast and ceramic coat them.
Goo
RB Racing LSR 2-1 exhaust systems use either one or two slip joints depending on the model. We suggest you put a coating of Permatex 598B ULTRA BLACK in the slip joint. None of our slip joints use any clamps because then they wouldn't be slip joints anymore. The inner pipe gets hotter that the outer pipe and they grow into each other and form a tight seal. The 598B is a non hardening gasket material and will prevent any leakage from condensation that forms in the pipe and, with the usual carbon particles, will actually seal better over time. It also makes the pipes easy to take apart later on. Get a tube before you install your RB racing exhaust system.
All RB Racing LSR exhaust systems come standard with a machined and heliarced oxygen sensor boss just below your front exhaust port. This port is designed to accept and oxygen sensor (18mm x 1.5mm) which will allow you to use our RSR Air/Fuel Ratio Meter to tune and monitor in real-time your air/fuel ratio. Also, if you really wish to get 55mpg and kick ass, our RSR Fuel Injection's closed-loop heated O-Sensor will plug directly into this port.
Ease of Installation: LSR 2-1 Mounting Brackets
Evo Sportster: Tubular steel bracket replaces oem bracket (all rigid mount models). On 2004 models we supply a transmission bracket that attaches to the steel stamping that supported the mid part of the rear pipe. On 2004 models remove the large oem bracket which requires the removal of the rear final drive cover aft of the transmission. #30 Torx required to unhook rear brake rod.
Mounting Torques
For flanges and mounts we recommend 15 foot pounds of torque. On exhaust flanges you do not use any locking compound as our nuts are self-clinching. On bolts for frame and engine-mounted brackets we recommend that the threads be clean and that a low grade (Blue) thread locking compound be used with 15 foot pounds of torque. Bolts and nuts on our slotted brackets do not require a locking compound but can also be tightened to 15 foot pounds.
In lieu of torque wrenches do not overtighten exhaust flanges to the point where they bend. In the case of bolts going into transmissions and into frames also do not attempt to see how strong you are as aluminum threads and bolts are weaker than you and your wrench are. Simply tighten things till the bolt stops and give another partial turn to firmly snug it. The last bit of tightening actually stretches things a bit and the tension holds things tight. Tightening should always be done in a sequence. Never finally tighten one part then go to the next...Always loosely tighten things in sequence and then finally tighten things in sequence.
The exhaust should never be installed with any of its elements in tension. It has to rest in place without strain and be tigtened without strain.
We employ split lockwashers on most fasteners to prevent counter-rotation. This works surprisingly well if the bolt is properly torqued or tightened.
In any case, you have a responsibility to tighten things or at least check periodically as part of your normal maintenance. Harleys do shake and try to kill anything attached to, or even near them. If things get loose the additional shaking moment can break bolts and destroy threads.

Freedom of expression...do it while you can before someone decides to stick their nose in your business. Picture above is a Sportster based Redneck Mutant with a custom 00-1022 exhaust in Silver Ceramic.
New Ceramic Black Finish
We have a lot more people looking for durable black finishes and we think we have the best finishes on the market. In the late 70's and early 80's we tried all sorts of coatings and paints and even used porcelain on some of our products in the late 1980's. The newer ceramic finishes are tougher and we use both polished silver and semi-gloss black to complement our usual chrome offerings. Pictured above is a 00-1022 Sportster LSR 2-1 Turn Out in 1 3/4". Very clean bike..headed for XR land. The newest black finish is a dual coat process that gives additional protection against scratches and nicks and is .008" thick, providing two barriers against corrosion.
In 27 years we have tried all sorts of black finishes: Kal Gard, VHT, Techline, and others. We also in the mid 1980's we even tried porcelain for awhile. It chipped and the heat distorted the parts. Most finishes will not survive over a long period unless they have a base coat to cushion rock strikes and scratches. The surface has to be perfectly prepared and most applications can fail if run too soon at elevated temperatures as they are typically baked at 450 to 500 deg F whereas the cure takes place at around 750 deg F. Lower temperatures will not cure the resins and they will fail once the bike is run. To get around this dilemma we have found the best solution is a 2500 Deg F Ceramic cushion base coat and a secondary Black Semi-Gloss finish on top of this.
Black Ceramic finishes are therefore the most expensive as they involve a triple process. First the parts are polished to remove any tooling marks. Then the parts are zirconia media blasted to prepare the surface. The parts are base coated with a 2500 Deg F ceramic and baked. After this they are sprayed with an ultra high temperature black and baked a second time. The 2500 Deg F base or cushion coat adheres to the metal very well and provides insulation and corrosion protection. The black is a thinner coat and provides the smooth, dark black, finish we require.
Satin finishes scuff too easily so we do not use them.
The Semi-Gloss black finish can be cleaned with soap and water and scuff marks can be removed with Mother's Aluminum and Magnesium Polish.

Self-Tuning Myth
People have the idea that closed-loop systems are completely self-tuning and that they are going to sell you some add-on gizmo that will automatically tune your efi bike. This is a crock of shit. The truth is that every engine is different and, in the Harley world, difference is the norm as there are limitless engine build combinations.
In Detroit, Japan, or Germany, they spend thousands of man-hours developing base maps for their automotive applications. On top of these base maps goes the closed-loop feedback mechanism controlled by mathematical equations or algorithms that govern exactly how the closed loop operation will function. These base maps are not written so the vehicle will run perfectly without feedback i.e. maps are not designed for open-loop operation. The strategy for closed-loop operation is different as fuel requirements under different climatic and altitude differences can be as much as 30%. Unless the base map is constructed for the particular application, the O2 feedback mechanism will not work properly.
OEM correction schemes allow only very slight learning corrections or they will "throw" an error code. They do this for a very specific reason i.e. if things are going wrong, which is indicated by the system trying to correct out of bounds problems, then a sensor or something else is wrong. They are not designed to make large swings to correct calibrations that are way out of bounds.
Beyond Stupid
Some add-on boxes for late model O2 sensor equipped oem Harleys eliminate the O2 sensors altogether. Why in the hell would you want to take a self-adjusting, sophisticated system and turn it into a gas guzzling low mileage dumb efi system? Beats the hell out of us and, since we make closed loop efi systems, we do have some experience in this area.
You bike should be left in closed loop, tuned in closed loop and monitored with O2 displays in closed loop. Correction factors defined in the oem code cannot be exceeded. Maps have to be rewritten for the changes to the bike so the base map is in agreement with the oem algorithms.
Crystal Balls and Astrology
You win some, you lose some. Mostly we win. Like we always say it always depends on the tuner. This is not a parts changing business and we all know it's easiest to just change pipes and see what happens, but that's not science. The LSR 2-1 pipes, themselves, do not represent a "limit" as long as you choose the right pipe for your application. The rest of the equation is getting the parts and tuning to work together.
Just put the damn thing on the road, open her up, and see what she'll do. Let the metal scream.

Doug Vancil's hard running Top Fuel Harley sponsored by Vance and Hines has a 2-1 that looks like one of their Pro Pipes so when Carl asked us to build one we made sure the collector area wouldn't restrict each of the 400hp explosions that were coming from each cylinder. Carl qualified 8th out of 32 bikes at the final Las Vegas meet and ran in the sixes at over 200 mph so the 2-1 probably didn't hurt anything. His best speed is 214mph with the 2-1 so it didn't seen to hurt anything. Top Fuel is pure insanity and is addictive as Heroin for those involved. Like they say " Gasoline is for washing parts...Nitro is for Racing!".
The 175" PRP motor has 4 cams just like your Sportster engine.
Risk
These days people have all sorts of expectations. They want to be loved. They want to be admired. They don't want their chrome to turn colors. They want "numbers". They want assurances. They want guarantees, warranties, trial periods, and return policies. They don't want the part, they just want everything that goes with their household baggage. It's all part of keeping everything nice and tidy and "best". Fear of rejection. Fear of making any decision.
We just come in and make the best parts we can and that's all there is to it. The rest of the equation is too complicated. There are plenty of people who will assure you till hell freezes over. We don't have time for this.
For those of you who do not understand that 1450 Deg F of exhaust flame front will discolor chrome, don't order the parts, or just leave the bike on the trailer..or order the heat shields to cover up the underlying discoloration. Ceramic or chrome the pipes get really hot and heat shields provide an air gap to protect and hide things.... Melted tennis shoes, burned pants. Air is the perfect insulator.
It isn't the old days anymore. People with $35,000.00 toys roll up in the screaming fetal position. Joy used to be a basket case that you could get running. Brave new world.
Angst
The agony of decision making can drive a poor consumer insane..."What is the best?"...".."How does it compare?"..."What will I get, what will I gain?"..."When can I get it?"..."Should I get a Turn Out or a Slash Cut" pipe".."Will the chrome blue?"..."Can I talk to someone who has one?"..."How long have you been in business"...""I've never heard of you"... "How black is the black?"..."Why haven't I seen these before?"..."My bike is at the builder and he has to have the pipe by Friday or I lose my slot!"..."Is the silver as shiny as chrome?"..."I have a wazoo998 cam and billet rocker boxes and a 280 rear tire...will your pipe work?"
Right brain, left brain. Fear of rejection. Fear of being different. Social standing. It's all too much for most people to deal with.
Look at the pictures, take the Red Pill, and start your journey. It's that simple.
Remove the Angst
If you wish avoid any decision and stay right where you are, just take the Blue Pill. If the journey for truth and power excites your spirit, take the Red Pill.
