Dinan D660-0080 High Flow Middle Exhaust - Compatible with 2018-2020 BMW M550i

 # D660-0080 Dinan High Flow Middle Exhaust - 2018-2023 BMW M550i xDrive Stainless Steel - 3" - G30. 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. This sophisticated 'X' is not only the focal point of the system in terms of aesthetics but also the star when it comes to the effects on the sound. Promoting even flow to both banks of tips, the 'X' removes unwanted nuances in sound caused by uneven exhaust flow that is found in stock systems. Along with the inherent benefit of increased volume by removal of the resonator, the Dinan Middle Exhaust for the G30 M550i produces a louder, smoother and fuller exhaust note.. Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed. - Smoother, sportier sound - 3" (76mm) tubing replaces stock 70mm tubing for free flow - Deletes resonator between catalyst and rear muffler for increased volume - Includes X-pipe crossover made from mandrel bent tubing for minimum restriction - 100% 304 stainless steel construction - Bolt-on installation General Policies **Payment Method** - We gladly accept PayPal and All Major Credit Cards.
