AWE SwitchPath Catback Exhaust – BMW M3 / M4 (G8x)

OVERVIEW

The AWE SwitchPath Catback Exhaust for the G80 M3 and G82 M4 is a balanced, tuned system that delivers volume when you want it without droning at cruising speed. Replacing the factory muffler uncovers the pure sound of the S58: an aggressive response on throttle without waking the neighbors on the way home.

SwitchPath uses the factory valving and the M button, so tone changes on the fly with no extra remote. It is AWE's first SwitchPath exhaust for BMW to incorporate drone-canceling 180 Technology, and a bespoke X-pipe unlocks a smooth tone out of the engine.
