Active Autowerke BMW Gen 2 Signature 328i Exhaust N52 Performance

Optimal power, performance and sound are the core values of our Active Autowerke BMW 328i mid pipe, designed to fit BMW 325i, 328i, and 330i E9X N52 models. A free-flow single pipe design allows more exhaust flow than the stock BMW 328i exhaust system.

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

This exhaust features the Active Autowerke muffler resonator 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 Signature Rear Exhaust!

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


This Mid-Pipe is not an exact fit to the stock rear exhaust, some welding and modification may be needed.
Exhaust system requires cutting of the factory pipe for installation.  Dimensions and cutting points are highlighted in the instructions.
Some models have a round tubular pipe that makes the installation seamless. Other models have an oblong shape and will require welding instead of clamping.
