Dinan High Flow X-Pipe for BMW F80 M3 and F82 M4
Transform the sound and flow of your BMW M3 or M4 with the genuine Dinan High Flow X-Pipe for the F8x platform. This performance mid-pipe unlocks an aggressive, motorsport-inspired exhaust note with exotic undertones, while improving exhaust gas flow for a sharper, more responsive driving experience. If you want a serious M3 or M4 exhaust upgrade that delivers the aural recognition every M owner deserves, this is the X-pipe to choose.
Dinan’s custom X design is not a stamped compromise. It is engineered for maximum flow characteristics and precision sound tuning, echoing the iconic tone of the Dinan E9x M3 racing middle exhaust. Constructed from straight-through, mandrel-bent 2.75 inch T304 stainless steel with OE quality clamps and flanges, it is a high quality, durable and beautifully finished centre section that looks as good as it sounds.
