Although motorcycle baffles come in many different sizes, shapes, and materials, they are used for ii main reasons. Starting time, they reduce noise emissions, and 2d they create some back pressure.

In that location are a lot of dissimilar designs and models of motorcycle baffles. Some will focus on providing back pressure but not affecting the noise, while others volition effort to provide the all-time noise suppression possible.

Longer baffles will provide better noise suppression than shorter ones.

They will not make a motorbike completely silent; even so, they tin can reduce the noise by 3 to vii dB.

A expert baffle tin really suppress those higher-pitched notes and leave yous with a satisfying deep rumble. (And, of class, happier neighbors.)

Provide back pressure level

Although back force per unit area has been thoroughly discussed and oft considered non to have as big of an upshot on motorbike engines every bit many would expect it to take, it is still an important function of a healthy running engine.
