The Dinan Resonator Delete Kit for the F90 M5 amplifies the car's sound, introducing a more aggressive tone and increased volume compared to the stock system. When paired with the Dinan exhaust, it delivers a smoother, fuller, and more assertive note, befitting a high-performance sedan.
 
This kit replaces the hydro-formed factory resonator section with 80mm T304 stainless steel tubing, enhancing exhaust flow. Instead of the stock resonator, Dinan's kit features a beautifully crafted X-pipe made from mandrel-bent tubing, minimizing restrictions and promoting even flow to both banks of tips. This sophisticated X-pipe is the system's aesthetic and functional centerpiece, eliminating unwanted sound nuances caused by uneven exhaust flow typical in stock systems.
