Active Autowerke E9X Gen2 Signature Rear Exhaust N52 | 325i 328i 330i

Short description:
For E9X Chassis N52 325i 328i 330i - Active Autowerke Mid-pipe is required to fit onto Xi (AWD) and Touring models otherwise welding may be required to join to stock pipe.
Optimal power, performance and sound are the core values of our Active Autowerke BMW 328i exhaust system, designed to fit BMW 325i, 328i, and 330i E9X N52 models. A free-flow design and 80mm dual exhaust tips allow 35% to 40% more exhaust flow than the stock BMW 328i exhaust system.

The increased flow minimizes back pressure, resulting in substantial HP and torque gains. The brushed stainless steel construction makes a bold visual statement, while also increasing durability. This BMW 328i performance exhaust produces a sporty, yet mellow tone. 

Our system allows 14lbs in weight savings as opposed to the factory BMW exhaust.

This exhaust features the Active Autowerke Muffler and Noise Cancellation Chamber to assist in reducing/eliminating drone. Manufactured from 100% brushed 304 stainless steel, this clamp-on system is suited for the N52 owner looking to bring their BMW's performance to new heights.

This mid pipe is a perfect complement to our N52 Mid Pipe!

Add our BMW 328i Performance Tune for the best combination of power and reliability!
