Dinan Free Flow Axle-Back Exhaust System with Polished Tips for BMW F85 X5M / F86 X6M 2015-2019

The F85 X5M and F86 X6M stand out as the quintessential SUVs, renowned for their power and performance, earning accolades in numerous automotive publications that recognize them as the pinnacle of their class. With the ability to produce over 700 HP from a base tune, these vehicles deliver exceptional performance. To complement this capability, Dinan engineers have crafted an exhaust system that matches the power with a compelling exhaust tone, allowing onlookers to hear and appreciate the strength beneath the hood.

Designed to optimize exhaust flow by minimizing back pressure, this system enhances power output while producing a deep sound that remains refined during normal driving and pleasantly aggressive under hard acceleration. The incorporation of a Helmholtz chamber design effectively reduces resonance or "drone" at low RPMs, ensuring a comfortable cabin experience. The system's impressive technology is matched by its aesthetic appeal, featuring quad 89mm (3.5") black ceramic or polished laser-engraved exhaust tips that enhance its high-performance look. Constructed from 100% 16-gauge 304 stainless steel, it is built to withstand the test of time and resist corrosion. The design ensures straightforward, bolt-on installation using factory brackets and hangers for a seamless fit.
