Active Autowerke Signature X Pipe & High Flow Cats For Bmw E9x M3

BMW PERFORMANCE PARTS: Active Autowerke Signature X Pipe & High Flow Cats for BMW E9X M3 

Product Features: This exhaust system was designed and engineered to work with most after-market exhaust systems/mufflers on the market today without the need to cut, weld or modify anything. It is a true bolt-on that can be performed by most. This system uses a free flowing 100 cell high flow catalytic converter. Active Autowerke is able to improve on the factory X Pipe design by a scavenging effect that yields high horsepower gains. Dramatic weight savings are also gained when one compares the factory system at 40 lbs and the Active Autowerke Signature X Pipe weighting at a mere 25 lbs. Noticeable gains have been measured on the Active Autowerke Mustang Chassis dyno with a 12+ RWHP when adding this X Pipe to our Signature exhaust system and as much as 10+ RWHP when used to the BMW stock exhaust. The Active Autowerke X Pipe system is constructed of 100% 304 brushed stainless steel and has a industry standard warranty against rust. This latest addition to the Signature line up is a must for the true Enthusiast looking for performance increases.
