BMW Free Flow Axle Back Exhaust with Polished Tips - Dinan D660-0054A
The F85 X5M and F86 X6M are the quintessential SUV in terms of power and performance with accolades in numerous periodicals crowning them the pinnacle of their class. With the possibility of putting down over 700 HP with a base tune, these vehicles are no slouch. Dinan engineers wanted to match this impressive feat with an equally impressive exhaust tone that let those around these SUV's hear the power that lies beneath the hood as well as be able to show it. The exhaust system was designed to improve exhaust flow by reducing back pressure, resulting in increased power output and a deep sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Dinan also incorporates a Helmholtz chamber design that reduces resonance or "drone" at low RPM. The technology within the can is matched in impressiveness by its outward appearance and design as the system is built to exacting specifications to ensure a simplistic bolt-on installation. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features quad 89mm (3.5") black ceramic or polished exhaust tips for a tasteful high-performance look.
