Main function The primary function of the motorcycle exhaust pipe is to discharge exhaust gas from the engine to the outside of the vehicle, ensuring the engine operates normally after combustion. Noise reduction The exhaust gas produced by the engine is pressure and velocity, which creates significant noise. The exhaust pipe includes muffling structures that reduce and disperse sound waves through reflection and interference, thereby lowering exhaust noise for a quieter ride.
