Dinan 14-16 BMW M235i (F22) w/o M-Performance Valence Free Flow Axleback Exhaust System – Black Tips

Dinan engineers designed the F22 BMW M235i 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.
