The Berk Technology exhaust system is perfect for those wanting to release the performance and sound from their track driven BMW 135i. This is the same exhaust system used on our championship winning time attack car. This is the full race system, our lightest and highest performing model. This exhaust system replaces the entire OEM exhaust from the downpipes back. Larger 2.5 inch mandrel bent stainless tubing replaces the restrictive OEM crush bent tubing. The midpipes feature twin straight through resonators to aid in meeting sound requirements in place at some SCCA and NASA Autocross/Track events. All Berk Technology exhaust systems are 100% bolt on at the factory mounting points and do not require any special tools or modifications to the vehicle. Supports both twin turbo N54 and single turbo N55 BMW 135i variants. Includes all necessary hardware and/or gaskets for installation. NOTE: While this race exhaust system should have no problems passing sound restrictions at a track event, the loud and aggressive nature of a race exhaust may be a bit much for daily driven street use.
