Its job is to make a 4.4-liter twin-turbo V8 sound quieter. It does that job well. If you want to hear the engine you paid for, it is the first thing to go.\u003c\/p\u003e\n\u003cp\u003eThe Dinan High Flow Middle Exhaust for the 2020-2023 BMW F95 X5 M and F96 X6 M replaces that factory center section with 3.25 in. (83mm) T304 stainless tubing and a hand-crafted, mandrel-bent X-pipe where the resonator used to sit. The result is a louder, smoother and fuller exhaust note with less restriction than stock.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy the Dinan High Flow Middle Exhaust Uses a Mandrel-Bent X-Pipe\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eStamped X-pipes pinch the tube at every bend. Mandrel bending keeps the full diameter through the crossover, so flow stays even to both banks with minimum restriction. The X-pipe also balances pressure between the two sides of the V8, which smooths out the uneven tone you get from the resonated stock system. Tubing goes from the factory 80mm to 83mm along the way.\u003c\/p\u003e\n\u003cp\u003eIt is 100% T304 stainless steel with factory-like fitment and all mounting hardware included. On its own it adds volume and depth. Paired with the Dinan valved axle-back, you get the complete Dinan cat-back sound.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMiddle Exhaust Fitment and Legal Status\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBefore you order, check what is behind it.
