BMW G20 M340i / G22 M440i B58 Rvng 4" True Single Valved Exhaust

The Rvng 4" true single valved quad tip exhaust is built for the B58 M340i and M440i, Gen 2 and Gen 3.

Why you need it

Unlike dual-path designs, a full 4" mandrel-bent single pipe cuts backpressure for faster spool and a deep, aggressive note with the valves open, then a quieter tone for daily driving with them closed.
