Active Autowerke designed this valved axle-back because the stock M240i exhaust is too quiet for many owners. It keeps the BMW valve actuator in use, so the car still controls the valve the way it did from the factory.

What you get

  • Valved rear exhaust for the G42 M240i.
  • Uses the factory valve actuator.
  • More sound than the stock system while keeping good flow.
  • Four tip finishes: stainless brushed, matte black, carbon fiber, or carbon over black chrome.
