OVERVIEW
The Active Autowerke valved rear axle-back exhaust for the G42 M240i reuses the factory valve actuator for OEM-style valve control and exits through quad tips. It is built from 304 stainless steel in the USA and gives the car a deeper voice than stock.
Tips are offered in stainless brushed, matte black, carbon fiber, and carbon over black chrome.
