Active Autowerke BMW E9X M3 Signature X-Pipe w/ Straight Pipes (Race Use Only)

Active Autowerke is proud to release the highly anticipated Signature Track Pipe with X-Pipe and Connecting Pipes for the BMW E9X M3.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 eliminates the secondary cats and the primary cats meaning it is designed for off road use. There is also a High Flow Cat option available via V-Band clamp.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 BM
