Dinan 12-15 BMW 335i (F30)/14-16 BMW 435i (F32) Free Flow Axleback Exhaust System - Black Tips

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.
