Overview

The Active Autowerke valved rear axle-back replaces the factory rear section on the BMW G80 M3 and G82 M4. It gives a low, deep sound and keeps the stock valve control, so the car can still be quiet when you want it to be.

This page offers black, carbon fiber or carbon over black chrome tips.

What It Does

The G80 M3 and G82 M4 are fast, but the factory exhaust is muffled, and many owners feel the car does not sound like an M car. The axle-back opens up the rear of the system, and pairs with Active Autowerke mid pipes and downpipes for the full Active Autowerke sound.

Materials and Construction

Every rear section is test-fitted on Active Autowerke's in-house G80/G82 exhaust fixture, and Active Autowerke guarantees a precise fit on every G80 M3 and G82 M4. All installation hardware is included.
