For over 30 years, Active Autowerke has been the one to turn to for high-quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about.

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G

The Active Autowerke BMW F30 328I signature exhaust is located in a class all of its own. This product is a must for any enthusiast searching for true performance, added durability and an attractive weight advantage when it comes to the F30 328I performance signature exhaust.

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 BMW F30 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!

This muffler turns your 328I exhaust tone into a sporty but mellow tone that is not only exhilarating but non obtrusive on your ears.

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 328I performance exhaust has a modular design with its v-band clamps that makes fitment a snap. A revelation in BMW tuning.

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…from “just” a quality muffler upgrade.

Turbos love to exhale, and we are very anxious to continue to unearth just how much extra power is hiding in the stock exhaust system.
