Dinan Free Flow Axle-Back Exhaust for BMW | F33 | F36 | 435iDinan engineers designed the F33 and F36 BMW 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. The system is built to exacting specifications to ensure perfect fit using the factory hangers.
