RVNG 4.5″ True Single Valved Quad-Tip Exhaust – G80/G82 M3 & M4

There’s nothing else like it on the market. The RVNG 4.5″ True Single Valved Quad-Tip Exhaust is the first of its kind for the G80 M3 and G82 M4 platform — engineered to deliver unmatched flow, sound, and performance.

At the heart of the system is a massive 4.5″ mandrel-bent 304 stainless steel main section, the largest diameter exhaust available for this chassis. By maintaining a true single design from front to back, we eliminate the turbulence and restriction found in factory and dual-pipe aftermarket systems. The result is faster turbo response, maximum exhaust velocity, and a raw, aggressive note that stands apart from anything else.

When the valve is open, exhaust gases take the unrestricted 4.5″ path for the loudest, most aggressive tone possible. Close the valve, and the flow is redirected through a quieter route for comfortable cruising without drone.

Finished with quad RVNG signature perforated tips, the system blends OEM-inspired styling with motorsport-level performance.
