BMW 335i Signature Exhaust System Performance

The Active Autowerke BMW 335i Signature Exhaust System has been dyno-tested and proven to add an additional 15-22 RWHP, and is a must for the enthusiast looking to unleash more power quickly and easily from their BMW 335i.

This system increases airflow by more than 35% over stock. It utilizes a true X-pipe design, created to increase the exhaust system’s scavenging affect, which is less restrictive than the H-pipe design employed by most aftermarket exhaust manufacturers. The entire system easily bolts onto either the factory downpipes, or Active Autowerke downpipes:

The system was created with an anti-flex design and hardware to assure proper fitment at all times. The inlet pipes of the system are larger than OEM, and were created with a high-flow design. This is the only BMW 335i exhaust system currently on the market to feature a bracket that connects the two mufflers together – though the bracket is not visible.

There is no cutting required, and detailed instructions accompany the exhaust, ensuring owners will feel confident during installation. The entire BMW 335i Signature Exhaust System is constructed from stainless steel, including connecting pipes, X-pipe, and dual rear mufflers. Several adjustments points allow for the addition of rear diffusers.
