The Dinan High Flow X-pipe for the F80/F82 M3/M4 elicits an aggressive sound that is sure to capture the ear of all bystanders and delivers the aural recognition that all M3/M4 owners deserve. Coupled with the associated Dinan exhaust the sound is further perfected into an aggressive growl that harkens back to the Dinan E9x M3 racing middle exhaust. Rightly so, as the same custom 'X' that was used in that application is implemented on the new F8x chassis for that perfect mix of exotic undertones and raw aggression. Unlike a stamped x-pipe that is so common in the marketplace the Dinan 'X' is thoughtfully designed for maximum flow characteristics and by itself is a work of art. Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems (non-M Performance). Fitment with other axle back units is not guaranteed. Features & Benefits Includes X-pipe crossover made from mandrel bent tubing for minimum restriction, unlike stamped X-pipes Stock hydro-formed 65mm tubing is replaced by 2.75" (70mm) mandrel-bent tubing for free flow. Deletes both resonators, between catalyst and rear muffler. 100% 304 stainless steel construction. Includes mounting hardware. Bolt-on installation.
