BMW E46 M3 Valved Section 3 Exhaust

Brushed T304 Stainless Steel or Grade 5 Titanium

Overview

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.

Why It Works

  • Direct Replacement: Connects to any section 2.

  • Dual Sound Modes: Raw, high-revving S54 tone (open) or stock-like refinement (closed).

  • Material Options: Choose brushed T304 stainless steel for durability or Ti 6Al-4V Grade 5 titanium for ultimate weight savings.

Sound & Control

  • Valves Open: Unleashes the iconic S54 scream with increased volume and sharper tone.

  • Valves Closed: Quiet, refined, and suitable for daily driving.

  • Rapid Valve Actuation: Instant open/close functionality for on-demand sound changes.
