BMW X5 M Performance Exhaust - Dinan - Axleback, Freeflow - Polished - 2015–2018. Purpose-built for the F85 X5 M, this axle-back system improves exhaust flow and delivers a controlled motorsport tone in a direct bolt-on package.

Constructed from 100 percent 16 gauge 304 stainless steel, the Dinan Free Flow Axle-Back reduces back pressure for better response and a deeper voice without intrusive cabin drone, thanks to an integrated Helmholtz chamber. The factory electronic valve strategy is retained for quiet operation during light driving, then full flow under load. Quad 89 mm polished, laser-etched tips complete the look, while factory brackets and hangers ensure straightforward installation. Dinan reports gains of up to 8 hp and 7 lb-ft at 6000 rpm on the F85 platform.
