Dinan D660-0045-BLK Free Flow Axle-Back Exhaust - Compatible with 2012-2016 BMW 335i/435i

Dinan engineers designed the F30 BMW 335i 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. The system is built to exacting specifications to ensure perfect fit using the factory hangers. It is made from 100 percent 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 89mm ceramic black exhaust tips for a tasteful, high-performance look. Fits: BMW; 3 Series, 4 Series; 335i, 435i; Coupe, Sedan, Convertible; F30, F32, F33; 2012-2015 335i and xDrive F30, 2014-2015 435i and xDrive F32, 2014-2015 435i Convertible F33.
