Akrapovic Downpipe with Cat (SS) BMW G8x M3/M4 and Competition 2021+

This high flow downpipe has been constructed with industry-grade high-quality stainless steel material that features a pair of sporty catalytic converters with heat insulation. The downpipe has been manufactured specifically for the BMW G80 M3 and BMW G82 M4 that provide a perfect fit. Once fitted to the cat-back exhaust, you will see the best out of your machine from the manifold to the tailpipes, further enhancing the performance. The downpipe was developed and tested together with the titanium exhaust system. At high revs, the downpipe produces a pure racing sound full of emotions with great feedback. 

Please Note: Remapping the ECU is mandatory to prevent the potential check engine light warning signals. This product is meant for racetrack close course use only. It does not meet emission compliance requirements for street or highway use.
