Dinan Free Flow Axle-Back Exhaust for 2013-2016 BMW M5 F10 - D660-0044-BLK

Wake up the exhaust character of the F10 M5 with the Dinan D660-0044-BLK Free Flow Axle-Back Exhaust. Designed for 2013-2016 BMW M5 applications, this dual-in/four-out system combines T304 stainless steel construction, twin chambered mufflers, a straight-through canister design, and four 3.5-inch black ceramic coated exhaust tips. Dinan engineered the system for increased exhaust flow with reduced backpressure while listing a maximum gain of 8 HP.

Sound control is built into the system rather than treated as an afterthought. Dinan incorporates Helmholtz chamber and butterfly valve technologies to help reduce unwanted cabin drone while allowing the M5's V8 to produce a deeper, throatier exhaust note under acceleration. The stainless steel system mounts using the factory brackets and hangers, while the laser-engraved black ceramic quad tips give the rear of the F10 a more aggressive appearance.
