Dinan 16-18 BMW 340i (F30)/17-20 BMW 440i (F32) Free Flow Axleback Exhaust System - Black Tips

Dinan engineers designed the F30 340i and F32 440i 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. Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or"drone" at low RPM.

Genuine Dinan. Part number D660-0055-BLK.
