The Performance of Motorcycle Exhausts
Motorcycle exhaust functions in the same way as car exhaust. Each system allows the engine to breathe by releasing waste exhaust gases out of a tailpipe. Aftermarket motorcycle exhaust increases engine performance, enhances sound and increases fuel economy.
Components & Function
-
Motorcycle exhaust includes all the major components of a car exhaust, but in a condensed format because of the reduced vehicle size. Header pipes secure to the engine cylinder ports where exhaust first exits the combustion chamber. The gasses then run down a mid-pipe before entering into a catalytic converter, muffler and tailpipe. Motorcycles use slip-on exhausts after the mid-pipe, which includes the catalytic converter, muffler and small tailpipe in one component. Slip-ons may be made of aluminum, chrome, carbon-fiber or stainless steel.
Engine Performance
-
Exhaust flow and velocity affects engine performance. Piping diameter controls the rate of gas flow and velocity. Small piping may constrict flow, which decreases top-end engine power and fuel efficiency
. Large piping increases flow but reduces velocity, which reduces torque. Aftermarket manufactures find the balance between flow and velocity for optimal motorcycle performance gains.
-
Backpressure
-
Backpressure occurs when exhaust returns into the engine because of piping obstructions or sizing issues. Backpressure suffocates the engine, reducing power and fuel efficiency.
