Dinan 15-18 BMW X5 M Freeflow Axleback Exhaust System - Polished

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.
