The M exhaust system is an important component in ensuring optimum power and torque as well as engine speed management with an M engine. It also serves to give each M car its very special, characteristic sound. This is one of the reasons why all M models come with a large silencer providing that signature rumble of power and muscle.
The double-chamber stainless-steel exhaust system is dominated by four powerful-looking tailpipes: not only do they signal the impressive sporting strength of BMW M automobiles, but they are also a further element contributing to these cars' special sound, the expression of their power.
