Active Autowerke's mid-pipe for the M340i and M440i removes the resonator from the Y-section of the factory mid-pipe. That gives a deeper tone and a bit more volume, whether you're on the stock rear exhaust or an aftermarket one.

What you get

  • Mid-pipe without the factory Y resonator.
  • Deeper sound with the stock exhaust or an aftermarket rear section.
  • Brace included. Pick the version that matches your car: 2024 and older with the G2X brace, or 2025 and newer with the Active brace.
