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.
