Active Autowerke is proud to release the much requested Signature Single Mid-Pipe for the BMW G80 M3 and G82 M4. This brings our expertise with a single mid-pipe from the F8X M cars to the G8X M cars and is an alternative to our X-Pipe Mid-pipe for the G8X.It provides a slightly deeper tone to the exhaust at a similar price point but without the option of secondary cats. 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 two 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 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. There are 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 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.
