The Dinan High Flow X-pipe for the F8x 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. The Dinan X-Pipe removes the factory center section after the secondary catalytic converters, including the large resonator. In its place Dinan introduces straight through mandrel bent 2.75" T304 stainless steel tubing and the custom 'X' for better flow, and an improved throaty sound. In addition, the kit comes complete with mounting hardware, OE quality clamps and flanges, for simplified installation. Sound Note: Since a resonator is deleted there is potential for increased cabin noise associated with the Dinan High Flow X-Pipe.

Fitment Note: Only confirmed to fit with the Dinan Free Flow Axle Back and stock exhaust systems. Fitment with other axle back units is not guaranteed.
Any tuning/performance-based mods/work/quotes and products are strictly for off-road and motorsport use only. Performance mods/certain exhaust systems will cause your vehicle to fail the MOT emissions test, therefore rendering the vehicle unroadworthy and illegal to be used on UK roads. PLEASE BE AWARE – Sports cats can NOT legally be installed on a vehicle for use on a public road that was manufactured after 1st March 2001 unless Type ECE 103R is approved (identified by ‘103R’ in the exhaust product title). Fitting a Cat/Cat Bypass or GPF delete/bypass to a vehicle that is to be used on UK roads will cause the vehicle to fail the MOT emissions test, therefore rendering it unroadworthy and illegal to be used on UK roads. Please note that UK regulations specify that the nearside and offside front door windows, for which the driver uses for forward vision, and when using external rear facing mirrors, must permit a light transmittance value of at least 70% ( for motor vehicles first used on or after 1st April 1985), with the front windscreen permitting a light transmittance value of 75% Please note that factory fitted windows are already tinted and by adding additional tinting, this may result in vehicles no longer being compliant for Road use.Read more
