For Your 2020+ BMW M3, M4 with the S58 Engine
We are excited to present our Rvng 3″ Race Downpipes for the S58 G80/G82/G83 M3 and M4. These 3″ downpipes offer the best value for money for your S58, with performance gains of up to 27hp and 33tq when tuned. By removing the restrictive catalytic converters found in the factory downpipes, back pressure is greatly reduced, leading to faster spool times, increased power, and a more aggressive exhaust sound.
Unlike many competitors, our 3″ race downpipes maintain a full 3″ design up to the last few inches of the pipe, enhancing flow. Handcrafted from SS304 stainless steel, our 3″ downpipes come with a lifetime warranty and our “No Hassle” satisfaction guarantee, covering fitment and defects.
This item fits the following BMWs:
2020 – 2023 G80 BMW M3 RWD & AWD including Competition
2020 – 2023 G82/G83 BMW M4 M3 RWD & AWD including Competition
2023+ G87 BMW M2 RWD
