Active Autowerke released their patented Signature Equal Length Mid-Pipe for the BMW G80 M3 and G82 M4. This brings their expertise with developing the first equal length mid-pipe from the F8X M cars to the G8X M cars. It 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 drivers side exhaust longer than the passenger side - this equal length mid-pipe corrects the passenger side exhaust length giving the G80/G82 a true equal length and smoother sound. This equal length technology has been recognised as unique with our US Patent 11248511 and patent pending in UK and EU. 

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 an 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.
