After extensive research and development, ACTIVE AUTOWERKE has announced GEN 2 of our EL midpipes. We worked with our factories to create specially developed RESONATORS that remove rasp from the exhaust tones with minimal change in the volume of the sound. A side benefit is that this also resulted in a reduction in the "2k buzzing" annoying to some BMW owners as well as a reduction in the cold start rattle from the factory. GEN 2 will replace the existing EL midpipe, so Active Autowerke has developed an upgrade program for EL existing owners who want to take advantage of this improvement. THIS PROGRAM IS VALID FOR ORIGINAL PURCHASERS OF EL MIDPIPES ONLY - proof of purchase required. Contact Active Autowerke for details on this program.
We are recommending to owners of cars with after-market downpipes to use the resonated version but we have only tested with stock and Active downpipes and stock and Active rear exhausts.
With stock downpipes, there is some small rasp so you may also want to opt for the resonated version.
Includes $90 fixed price shipping in lower 48 states.
WE DO NOT GUARANTEE RESULTS OR FITMENT WITH OTHER MAKES OF REAR EXHAUSTS.

At the repeated requests from our customers, Active Autowerke is pleased to release the first ever Signature Equal Length Mid-Pipe for the BMW X3M and X4M. This brings our expertise with building the first equal length mid-pipe from the F8X and G8X M cars to the X3M and X4M SUVs. It provides a more aggressive and sweeter high revving tone to the stock exhaust.
While these SUVs 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 vehicle. In order to solve this, Active Autowerke has created a full exhaust system for the X3M/X4M which comprises a choice of two midpipes - either a single midpipe or this new equal length midpipe, a rear axle-back valved exhaust and a set of GESI catted downpipes. Together, this remake of the stock exhaust results in a X3M/X4M with an amazing sound. You will feel like you are driving a true M-car.
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 each side of 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.
Active Autowerke is able to improve on the factory mid-pipe by mixing the sounds earlier and for a longer period creating a deeper tone to the exhaust sound.
The Active Autowerke single mid-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 stock mid-pipe for better sound and flow.
