Active Autowerke Signature X-Pipe & High-Flow Cats – BMW M3 (E90 / E92)

OVERVIEW

The Active Autowerke Signature Track Pipe for the BMW E9X M3 combines an X-Pipe and connecting pipes with free-flowing 100 cell high flow catalytic converters. It improves on the factory X-pipe design with a scavenging effect that yields horsepower gains while cutting weight from the factory system's 40 lbs to a mere 25 lbs, and it was designed and engineered to work with most aftermarket exhaust systems and mufflers on the market today — a true bolt-on that most owners can perform, with no need to cut, weld or modify anything. Construction is 100% 304 polished stainless steel, carrying an industry standard warranty against rust.
