The X3 M and X4 M sound muted from the factory. Active Autowerke's valved axle-back replaces the rear section of the exhaust to bring more M-car character to the sound, and it is the rear piece of the brand's three-part system with its single mid-pipe and GESI catted downpipes.

What you get

  • Valved axle-back exhaust for the rear section.
  • More sound than stock, while keeping valve control.
  • Fits into a full system with Active Autowerke's mid-pipe and downpipes.
  • Four tip finishes: stainless brushed, matte black, carbon fiber, or carbon over black chrome.
