Active Autowerke G80 M3 and G82 M4 Valved Rear Axle-back Exhaust

Upgrade your BMW G80 M3 or G82 M4's sound with Active Autowerke's Valved Rear Exhaust. This rear axle-back exhaust is a part of the full exhaust system upgrade that Active Autowerke has created for the G80/G82. The system comprises this rear exhaust, a mid-pipe with x-pipe or single, and a set of GESI catted downpipes. Together, this system creates an amazing sound that will make you feel like you are driving a true M-car again.

Maximize the enjoyment of your drive with Active Autowerke's performance parts. With over 40 years of experience, Active Autowerke has developed a refined, quality product that focuses on not only making as much power as possible but also on maximizing the driving experience. The introduction of the G80/G82 BMW M3/M4 collection rear exhaust is a testament to this philosophy.

The Active Autowerke G80/G82 rear exhaust was carefully engineered to increase the sound level over the factory exhaust while allowing for optimum flow and resonance. The exhaust reuses the actuators from the BMW valves to achieve this. The stock OEM exhaust is overly quiet, but with Active Autowerke's rear exhaust combined with the mid-pipe and catted downpipes, your BMW will have the deep, throaty growl that a car of its caliber should have had from the factory.

Please note that there is a version of this rear exhaust available for those who only wish to replace their stock rear section while keeping their stock mid-pipes. However, if you later move to an Active or other mid-pipe, the connecting pipes will have to be replaced, and there will be an additional subsequent charge. The rear exhaust offers an upgrade, but the dramatic difference in sound will only come with replacing the mid-pipe. Order now and experience the best combination of sound and performance for your BMW G80 M3 or G82 M4.
