Active Autowerke is proud to release the highly anticipated 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. For the product launch, we are shipping systems without the secondary cats so you will need to provide an affidavit for race use.

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 upcoming option replaces the restrictive secondary cats with high-flow 100 cell flat cats that changes 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 line up is a must for the true Enthusiast looking for a better sounding car to match amazing performance.

Features:
  • Durable 100% 304 Stainless Steel
  • Only single cut needed with Factory Style Flanges and clamps
  • Install to all systems that use factory style fitting
  • One year warranty
  • Replaces (not removes) secondary cats for better flow and sound
