Dinan Free Flow Axleback Exhaust System - BMW 340i (F30) / BMW 440i (F32) - Polished 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.
This listing covers the Dinan Free Flow Axleback Exhaust System for the BMW 340i (F30) and BMW 440i (F32), polished tips.
Note: Please confirm your vehicle's model, chassis code and year against the fitment table before ordering.
