Akrapovic Downpipe Stainless Steel With/ Catalyst M3/M4 G8X

Developed to be used in conjunction with the Akrapovic Slip-On Line (Titanium) and the Evolution Link Pipe Set (Titanium), this high-quality stainless steel downpipe set features a pair of sporty catalytic converters (200 cpsi) with heat insulation. The front part of the downpipes is cast in the in-house foundry, providing a perfect fit. 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.
