For the G80 M3 and G82 M4, Active Autowerke's valved axle-back swaps out the factory rear exhaust to get rid of the muffled stock sound. You can run it alone or as the rear piece of the brand's full system with its X-pipe or single mid-pipe and GESI catted downpipes.

What you get

  • Valved axle-back replacing the factory rear section.
  • Louder, more characterful sound than stock.
  • System-ready. Built to work with Active Autowerke's mid-pipes and downpipes.
  • Four tip finishes: stainless brushed, matte black, carbon fiber, or carbon over black chrome.
