Transform your BMW M3 or M4 with the Active Autowerke (AA) Signature Exhaust System. This premium stainless-steel BMW F80 M3 exhaust and BMW F82 F83 M4 exhaust is engineered for the S55, delivering a deeper, smoother exhaust note, quicker spool, reduced back pressure and exceptional build quality.

Developed through extensive R&D, the AA Signature Exhaust uses a large single 3.5" pipe straight after the downpipes to promote exhaust scavenging and increase exhaust velocity. The result is a sharper throttle response, faster turbo spool and a refined tone without the unpleasant rasp of the factory dual-pipe layout. Constructed from 100% 304 TIG-welded stainless steel with a flow-efficient Y-pipe and adjustable 90 mm double-walled tips, it is built to perform and built to last.
We have run this system on our own customer cars and feedback has been outstanding for sound quality, drivability and fitment. It is exactly what F80 M3 and F82 F83 M4 owners in the UK look for when upgrading an S55 exhaust.
