The Dinan D660-0081 Resonator Delete Kit replaces the hydro-formed, resonated mid-section on the F90 BMW M5 with 83 mm (3.25 in.) T304 stainless steel tubing and a mandrel-bent X-pipe. Removing the resonator opens flow, balances exhaust pulses, and delivers a louder, smoother, fuller V8 note while retaining factory catalytic converters and rear muffler. The assembly bolts in place with the supplied hardware and pairs seamlessly with the Dinan axle-back exhaust for further sound gains.
