Active Autowerke BMW M3/M4 Signature Midpipe With X Pipe (G80/G81/G82/G83)

Active Autowerke Signature Mid-Pipe with X-Pipe for the BMW G80 M3 and G82 M4. While these cars have received rave reviews for their performance, the sound is a muffled one leaving the driver to wonder if they are really driving a BMW M-car. In order to solve this, Active Autowerke has created a full exhaust system for the G80/G82 which comprises this mid-pipe, a rear axle-back valved exhaust and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a G80/G82 with an amazing sound. You will feel like you are driving a true M-car again. We are shipping systems with or without the secondary cats to fit your driving need. The catted version drops the exhaust volume very slightly and provides a slightly deeper tone.

This exhaust system upgrade was designed and engineered to work with most after-market exhaust systems/mufflers on the market today with only a single cut needed in the stock mid-pipe. It is a bolt-on that can be performed by most and the stock mid-pipe can also be reinstated if needed.

This system provides the maximum flow available and restores the sports car growl expected from a BMW M-Series car. An available option replaces the restrictive secondary cats with high-flow 100 cell flat cats that change the sound slightly providing a deeper sound. There are also plans for a future resonator upgrade for those who prefer a smoother sound to their exhaust systems.

Active Autowerke is able to improve on the factory mid-pipe by increasing the flow and removing the two sets of resonators. The X-Pipe design has a scavenging effect that yields modest horsepower gains.

The Active Autowerke X Pipe system is constructed of 100% 304 brushed stainless steel and has a industry standard warranty against rust.

This latest addition to the Signature lineup is a must for the true Enthusiast looking for a better-sounding car to match amazing performance.
