This system is constructed from 100% 304-stainless steel and features adjustable Active Autowerke double walled tips, making it ideal both for 2-door and 4-door models (also allows for cleaner fitment with diffusers).

The sound is unobtrusive, with a rich mellow tone and delivers a solid 5+hp, with key gains in the mid-range. In addition, the Active Autowerke E9X M3 Signature Exhaust system features large 3" piping for maximum exhaust flow while maintaining enough back-pressure to result in horsepower increases across the entire RPM range.
