From outside the car, the factory exhaust makes it sound a lot more polite than that. The valves open, you get a hint of what is going on, and then the muffler swallows the rest. You paid for eight cylinders. You should get to hear all of them.\u003c\/p\u003e\n\u003cp\u003eThe Dinan Valved Axle-Back Exhaust for the BMW F95 X5M and F96 X6M replaces the factory rear section with 83mm T304 stainless tubing, twin 76mm secondary valves and four 4.5 in. black ceramic tips. Dinan measured +6 HP and +5 lb-ft at 6600 RPM, and in Dinan's words it lets \"the full chorus of all 8 cylinders\" come through.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow the Dinan X5M Axle-Back Exhaust Balances Sound and Comfort\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a daily-driven SUV, and Dinan built the system that way. The muffler reduces low-RPM drone, so a long highway run does not wear you out. The factory computer-controlled valves are kept and work exactly as before: closed at low speed and light load, fully open under hard acceleration. Your M exhaust button still does what it did from the factory. The difference is what comes out when the valves open.\u003c\/p\u003e\n\u003cp\u003eTubing grows from the stock 80mm to 83mm, and the twin 76mm secondary valves are 30% less restrictive than the OEM parts. Everything is 100% T304 stainless steel, TIG welded with a brushed finish, and the four double-walled 114mm tips are finished in black ceramic coating.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eValved Axle-Back Exhaust Install and Legal Status\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFactory-like fitment with the included hardware and clamps, and a Dinan-quoted labor time of 2.7 hours. No coding needed since the factory valve control is kept. Dinan states this axle-back does not affect vehicle emissions and is legal for sale or use on emissions-controlled vehicles. Pair it with the Dinan High Flow Middle Exhaust on 2020-2023 cars for a fuller build. Dinan part number D660-0090-BLK.
