The Dinan D660-0080 middle exhaust replaces the hydro-formed, resonated factory center section on the G30 M550i with 3 in. (76 mm) T304 stainless tubing and a mandrel-bent X-pipe. The X promotes equalised flow between banks and, by deleting the resonator, produces a louder, smoother, fuller V8 soundtrack. The system bolts to stock or Dinan rear sections using the supplied hardware.
