What are Baffles for?
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.
