The Valvetronic Designs Valved Section 3 brings modern exhaust control technology to the legendary BMW E46 M3. Designed to replace the heavy factory suitcase muffler, this upgrade delivers an unmatched S54 soundtrack with the ability to switch between aggressive and stock-like tones at will.
With the valves open, the E46 M3 comes alive—raw, responsive, and engaging throughout the rev range. Close the valves, and the sound reverts to factory-like levels for a stealthy, comfortable drive.
