After extensive R&D, Active Autowerke proudly introduces the Gen 2 Signature Equal Length Mid-Pipe with X-Pipe — a refined evolution of our patented exhaust technology, now engineered specifically for the BMW G80 M3 and G82 M4.

Featuring newly developed resonators, the Gen 2 system eliminates unwanted rasp and drone while maintaining the aggressive tone enthusiasts expect. This update also reduces the infamous 2k rpm buzz and tones down the factory cold-start rattle, creating a smoother, deeper, and more sophisticated exhaust note throughout the rev range.

Building on the success of our original F8X Equal Length Mid-Pipe, this G8X version corrects BMW’s factory over-compensation in exhaust length — precisely balancing both banks for a truly equal-length configuration. The result is a smoother, high-rev scream that transforms the S58’s muted tone into an unmistakably authentic BMW M sound.

Engineered Precision. Motorsport DNA.

Designed for racing and off-road applications, this mid-pipe delivers maximum exhaust flow and restores the raw character missing from the stock system. Its bolt-on design requires only two clean cuts to the OEM mid-pipe and integrates seamlessly with most aftermarket or factory-style rear sections.

Whether paired with stock or Active Autowerke GESI downpipes and rear valved exhaust, this setup produces a balanced blend of performance, tone, and craftsmanship that defines the Active Autowerke Motorsport Collection.
