Performance Exhaust Tech With Samson

Located in Brea, California, Samson Motorcycle Products is the brainchild of inventor and bike wrench Kenny Price. Kenny was so good at making custom pipes for his choppers that it earned him the nickname of Godfather of Pipes in the 1960s. Still designing today, Kenny is now offering innovative exhaust products for Harley Davidson, Indian and Metric Cruiser motorcycles. Kenny is involved in every aspect of the designing and manufacturing of all pipes made at Samson. Samson still exists as a family owned business that has an enthusiast mindset and genuine passion and connection in the motorcycle industry.


One of the most important things that sets Samson apart is its eagerness to serve its customers with dignity and superior service. With this in mind, Samson wanted to share with Bikernet readers some interesting knowledge about performance motorcycle exhaust. The following Q&A has been compiled by the people at Samson to help folks with the selection process of performance motorcycle pipes. It also answers more general tech questions as they relate to pipes. There’s valuable information in this tech story, whether or not your are ready for an exhaust upgrade.

Q: What are the advantages of the True Dual Crossover System?
A: Models are equipped with factory installed left and right factory exhaust are equipped with a connector pipe which connect the front and rear cylinder exhaust pipes. This exhaust configuration is a contributor to excessive exhaust back pressure on the right side muffler. 100% of the exhaust from the front pipe and about 70% of the rear pipe are being forced through the right side muffler. This means that the left side exhaust is more cosmetic than functional. Only about 30% of the exhaust flow and exhaust note comes from the left side muffler. About 70% of the exhaust flow and heat exits through the right side pipe and muffler. The Samson True Dual Crossover system eliminates the connector pipe found in stock systems; this means that each cylinder has its own separate exhaust pipe. This allows for a much more free flowing exhaust from each cylinder to each muffler. Therefore, the Samson True Dual Crossover System greatly increases torque and horsepower.

Q: What are torque cones for?
A: Torque cones are used to create a higher velocity of exhaust flow in the exhaust pipe. This higher velocity generates an increase of torque from the engine. There are two other performance benefits gained from the use of torque cones. One is the creation of velocity, which actually scavenges the exhaust from the exhaust port more efficiently. This assists in evacuating gasses from the engine. The other benefit is that the torque cones help create an anti-reversion effect. This eliminates the tendency for spent gasses to be sucked back into the combustion chamber during the engine’s intake stroke. The value of anti-reversion is a cleaner air fuel burn during combustion and a cooler running engine.

Q: Do I have to rejet with a slip on?
A: In most cases where the slip-on has a baffle no rejetting is necessary. However, you should rejet if you are running a slip on with no baffle.

Q: Do Samson exhausts contain everything needed for installation?
A: Samson pipes are shipped complete with a bracket and hardware kit to make installation easy along with an instruction sheet to walk you through the process. If there is any type of OEM part required we will let you know in the instructions.

Q: Will the installation of Samson Exhausts increase the performance of my motorcycle?

A: With proper tuning all Samson exhaust systems will increase power. Samson suggests proper tuning with the installation of any engine accessory.

Q: I have a 2007 – 2008 Harley. Do I need to do anything to my bike as far as remapping my module is concerned?
A: Not necessarily. Most bikes will not need to be remapped. The new modules for 2007 and 2008 do not need to be remapped. The new modules have a wider self adjustment. If more modifications are performed on the bike remapping may be required.

Q: I have a fuel injected bike, 2006 or earlier. Will I need to remap my module?
A: Not necessarily. Most modules will remap themselves to adjust to the free flowing pipes without other modifications. If other modifications are made you may need to remap your module.

Q: Is rejetting required with your exhausts?
A: Samson does recommend rejetting with our exhaust systems if it has not been done previously

Q: What are Baffles for?
A: Baffles are generally used to reduce the sound level of the exhaust note. The secondary value of baffles is that they help created back pressure in the exhaust system. Back pressure helps the engine create torque. The narrower the inner diameter of the baffle, the more back pressure, therefore the higher torque value. Very high performance engines may not require as much exhaust back pressure restrictions created by baffles.


Q: What causes bluing and/or discoloration?
A: The main cause of bluing and/or discoloration is the result of improper tuning, cam timing, engine timing, jetting, overheating etc. Small diameter mufflers can also blue and/or discolor due to the heat generated by their size. It is not caused by defective manufacturing.

Q: What is your Sinister Black finish?
A: Sinister high temp metallic ceramic coating was designed to provide ultimate adhesion and corrosion protection capable of 2500 degrees. Sinister black also retains heat inside the pipe to maximize power whereas the outer surface remains much cooler for an improved ride for both the rider and the passenger.

Q: What type of finishes do you offer for your products?
A: We offer an exclusive “Quad Chrome” show finish for our products. This finish comes from the highest quality chroming process in existence. We also offer the Sinister Ceramic Black finish for many of our most popular pipes.
