Fabspeed BMW M3/M4 (G80/G82) Sport Cat Downpipes (2021+)

Give your G8x M3/M4 more sound and power with our high-flow catted downpipe. Fabspeed Motorsport's engineering team consulted with HJS Motorsport and chose the largest HJS catalytic converter that would fit the G8x chassis. This guarantees the most exhaust flow, reliability, and sound. Our Sport Cat Downpipe will flow 93% of a 3'' straight pipe, all while providing emissions compliant performance and O check engine light. There's no need to run cat bypass pipes!
