Active Autowerke BMW M3/M4 Signature Equal Length Midpipe (G80/G81/G82/G83)

The Active Autowerke equal-length midpipe for the G80 M3 & G82 M4 provides the advantages of an equal-length exhaust system with a smoother high rev sound. BMW provided an equal-length solution with the crossover pipe from the short downpipe. However, they overcompensated and made the length of the driver-side exhaust longer than the passenger side – this equal-length midpipe corrects the passenger-side exhaust length giving the G80/G82 a true equal length and smoother sound. Our equal-length technology has been recognized as unique with our US Patent 11248511 and patent pending in UK and EU.

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 a choice of three mid-pipes (this one, the single or our x-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.

This exhaust system upgrade was designed and engineered to work with most after-market exhaust systems/mufflers on the market today with only two cuts 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.

The Active Autowerke equal-length 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 an alternative to the stock S58 sound of the G8X platform to match the amazing performance.
