Description
Transform the sound of your BMW G80 M3 or G82 M4 with Active Autowerke's Valved Rear Axle-back Exhaust. While these high-performance cars excel in many areas, their stock exhaust often leaves drivers longing for a more aggressive, M-worthy exhaust note. Active Autowerke addresses this by offering a complete exhaust system that includes this rear axle-back valved exhaust, a mid-pipe (with x-pipe or single options), and GESI catted downpipes. Together, this combination delivers the deep, resonant growl that your M3 or M4 should have had from the factory.
This rear exhaust is engineered to enhance sound without compromising the factory valve control. By reusing the OEM valve actuators, the system optimizes both sound and flow, ensuring your M-car roars to life. Active Autowerke’s attention to detail ensures that each exhaust fits precisely and is rigorously tested on in-house G80/G82 exhaust fixtures to meet the highest quality standards.
For those who wish to keep their stock mid-pipes, a version of this exhaust is available, but the most significant sound improvement comes from combining it with an aftermarket mid-pipe.
Key Features:
- Made in the USA from high-quality 304 stainless steel
- Low, deep exhaust sound with stock valve control
- Guaranteed to fit all G80 M3 and G82 M4 models
- Each exhaust is test-fitted on an in-house G80/G82 exhaust fixture
- Includes all necessary installation hardware
- Upgrade option available for future mid-pipe installations
Fitment:
- BMW G80 M3 (2021+)
- BMW G82 M4 (2021+)
Note: While this axle-back exhaust offers a subtle improvement in sound, the most noticeable difference occurs when paired with a mid-pipe replacement.
