Dinan D660-0045-BLK BMW 3.0 Exhaust System

Dinan engineers designed the F30 335i and F32 435i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty 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.\nThe system is built to exacting specifications to ensure the perfect fit using the factory hangers. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 3.5" polished stainless, or ceramic black, exhaust tips for a tasteful, high-performance look.\nThe factory computer-controlled exhaust valve is eliminated.
