Downpipe BMW M5 F90, M5 Competition, M5 CS S63M

High-quality catless downpipe for the BMW M5 F90, also compatible with the M5 Competition and M5 CS, all equipped with the S63M 4.4L V8 engine.

Exclusively crafted by KPerformance, our full 3″ downpipe maintains a bolt-on fitment while maximizing exhaust flow and minimizing backpressure, resulting in sharper throttle response, increased performance, and a deeper, more aggressive exhaust tone.

Our downpipe consists of four pieces – two for each bank of the engine (cylinders 1-4 and 5-8). Each pair is joined using our stainless steel V-Band clamps, which are included in the kit.
