Active Autowerke Ultra High Flow Cats Upgrade for Signature X Pipe - BMW E90 M3 (2007-2013)
The Active Autowerke 11-083 is engineered for BMW E90 M3 owners who demand performance without compromising emissions compliance. This upgrade features GESI G-Sport cats, designed specifically to integrate seamlessly with the Active Autowerke Signature Track Pipe, allowing you to eliminate the check engine light (CEL) without the need for a tune.
Construction and Design
Crafted from 100% 304 brushed stainless steel, the 11-083 ensures durability and resistance to rust, backed by an industry-standard warranty. The system utilizes a casted upper stainless steel V-band for precise fitment, making installation straightforward with factory-style flanges—no cutting or welding required.
Performance Enhancements
The design of the 11-083 promotes a scavenging effect that significantly improves exhaust flow. Expect to see gains of over 10+ rear wheel horsepower (RWHP) when paired with the stock exhaust system, and up to 12+ RWHP when used with the Active Autowerke Signature exhaust. The weight savings are notable as well, with the 11-083 weighing in at under 30 lbs compared to the factory system's 40 lbs.
Key Features
- No CEL when using this downpipe
- Increase of 10+ RWHP
- GESI EPA registered high flow and fully OBD2 compliant
- Rated for 300 to 500 hp per cat
- Withstands temperatures up to 1500°F

- EPA compliant for use on OBD2 vehicles (1996 and newer) except in California and other CARB states
- Furnace-braised substrate for outstanding durability
- GESI proprietary precious metal loading technology for reduced emissions
- Weight reduction enhances overall vehicle dynamics
