This product is a must for any enthusiast searching for true performance, added durability and an attractive weight advantage. This system is constructed from 100% polished 304-stainless steel and features adjustable 80 mm double walled tips, making it ideal both for two-door and four-door models (which also allows for cleaner fitment with diffusers).
This exhaust delivers everything we know you would want in a performance exhaust: eye-catching style, a sophisticated yet aggressive tone, weight savings, and – most importantly – measurable horsepower performance gains!
The factory counterpart weighs 29 lbs. while the Active Autowerke Signature exhaust weighs only a mere 19 lbs. Weight savings are not the only attributes, this performance exhaust has a modular design with its v-band clamps that makes fitment a snap.
On the in-house Active Autowerke Mustang dyno, their otherwise 100% stock 2013 328I test mule spun the rollers to the tune of an extra 9 RWHP, and 13 LB-FT of torque.
**Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting measurements are included in the instructions.**
