Part # D660-0080

The Dinan Middle Exhaust for the G30 M550i introduces a more aggressive tone and an increase in volume over the stock system. Coupled with the associated Dinan exhaust, the sound is further enhanced into a smoother, fuller and more aggressive growl that is becoming of the V8 powered sedan. This full mid-section kit removes the hydro-formed factory center section, including the resonator, and replaces it with larger 3" T304 stainless steel tubing for freer flowing capabilities. In place of the factory resonator, Dinan incorporates a beautifully crafted X-pipe made from mandrel-bent tubing for minimum restriction, unlike stamped X-pipes which are commonplace in the market.


  • Smoother, sportier sound
  • 3" (76mm) tubing replaces stock 70mm tubing for free flow
  • Deletes resonator between catalyst and rear muffler for increased volume
