BMW G80 M3 / G82 M4 S58 Rvng 4.5" True Single Valved Exhaust

The Rvng 4.5" true single valved exhaust runs one 4.5" mandrel-bent 304 stainless pipe from front to back on the G80 M3 and G82 M4, finished with quad tips.

Why you need it

The true single layout cuts restriction and improves exhaust velocity for faster turbo response and the deepest tone in Rvng's lineup. Valve open, gases take the unrestricted 4.5" path; valve closed, they run through a quieter route with minimal drone.

Good to know

Intended for off-road and competition use only. Not legal for use on public roads in many areas. Clearance: fine at stock height and on most lowering springs, but very low cars will have less under-car clearance with the 4.5" pipe. Gains in power come with a tune.
