Dinan High Flow 3in Stainless Steel Middle Exhaust for 2018-2023 BMW M550i xDrive (G30) - D660-0080
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2018-2023 BMW M550i xDrive Base.
The Dinan High Flow Middle Exhaust replaces the restrictive, hydro-formed factory center section and resonator with a high-flow 3-inch (76mm) T304 stainless steel assembly. By stepping up from the factory 70mm diameter, this mid-section kit significantly reduces backpressure and improves exhaust scavenging. At the heart of the system is a precision mandrel-bent X-pipe, engineered to balance exhaust pulses between cylinder banks for a smoother, fuller tone while eliminating the unwanted sound nuances common in stock configurations.
Designed for a direct bolt-on installation, this kit includes all necessary mounting hardware to mate with your existing system. The deletion of the factory resonator increases exhaust volume and provides a sportier, more aggressive profile without sacrificing the refined character of the G30 M550i.
- 100% T304 stainless steel construction for long-term corrosion resistance
- 3-inch (76mm) mandrel-bent tubing replaces the factory 70mm section for increased flow
- Mandrel-bent X-pipe crossover ensures balanced exhaust pulses and improved scavenging
- Resonator delete design provides a louder, deeper exhaust note
- Full bolt-on installation with all required mounting hardware included
- Manufacturer Part Number: D660-0080
