BMW M550i xDrive Performance Exhaust - Dinan High Flow Middle Exhaust (2018–2023). A precision-engineered mid-section that replaces the factory center section to free up flow and enrich the V8 soundtrack.

This full mid-pipe removes the stock resonator and hydro-formed center, upgrading to 3-inch (76 mm) T304 stainless tubing and a mandrel-bent X-pipe for minimal restriction. The X promotes even flow between banks, reducing uneven tones common in stock systems for a louder, smoother, fuller note. It’s a direct bolt-on with included hardware. Confirmed fit with the stock rear mufflers and the Dinan Free Flow Axle-Back; fitment with other axle-backs is not guaranteed.
