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).

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 5+hp, with key gains in the mid-range.
