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. Please consult the media in the ‘Pictures/Video’ tab for a representative video to determine if the product is right for you. 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.
