Product Description

Transform the exhaust note of your S58-powered BMW with the Active Autowerke Gen 2 Signature Equal Length Mid-Pipe. Rather than simply making the G80 M3 or G82 M4 louder, Active’s patented equal-length design corrects the unequal exhaust path created by the factory system to produce a smoother, cleaner, and more exotic high-RPM exhaust note. The Gen 2 system takes the concept a step further with specially developed resonators designed to reduce rasp with minimal impact on overall volume while also helping minimize the characteristic 2,000 RPM buzz and factory cold-start rattle. Constructed entirely from brushed 304 stainless steel, the system improves exhaust flow while bringing considerably more character out of the S58. For G8X owners who dislike the factory exhaust tone and want a more refined sound than a traditional single mid-pipe, the Active Autowerke Equal Length Mid-Pipe is one of the most comprehensive ways to change the personality of the car.
