True performance, durability, and attractive weight advantages with innovative features places the Active Autowerke E9X BMW M3 exhaust in a class of its own. This system is constructed from 100% polished 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).
This system uses factory style flanges making it a complete bolt on system that requires no cutting or welding. The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust. The sound is unobtrusive, with a rich mellow tone and delivers a solid 15+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 backpressure to result in horsepower increases across the entire RPM range. Weighs 44 Lbs vs. the factory of 78 Lbs.
Since 1981, Active Autowerke has been known as the BMW innovators when it comes to BMW performance. All products come with a 2 Year Warranty.
