Downpipe w/o Cat (SS)

Developed to be used in conjunction with the Akrapovič Slip-On Line (Titanium) and the Evolution Link Pipe Set (Titanium), this high-quality stainless-steel downpipe has the catalytic converters removed. Delivering a pure racing sound full of emotion, this provides great feedback at high revs, without drone. Remapping the ECU is mandatory to prevent potential check engine light warning signals.

This product fits on xDrive, CSL, M3 Touring (G81), M4 (G83) Competition and Convertible models.

THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
