To achieve desired sound volume and tone Dinan felt becoming of the F9x X5M/X6M the tubing was enlarged to 83mm (vs 80mm stock) to allow freer flow throughout the entirety of the system. The larger tubing is fed into a muffler that is typical of all Dinan exhaust design and utilizes absorption and reactive technologies designed to improve exhaust flow and reduce backpressure. The combination results in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. This is partly courtesy of the retained computer-controlled exhaust valves that limit noise during low-speed driving and open fully during high-load conditions to allow free flow and greater sound as the bulk of the gases are bypassing the muffler. Like all Dinan exhausts, our X5M/X6M free flow exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. With the Dinan exhaust equipped on the X5M/X6M you get the best of both worlds; aggressive tone/sound and civility. A combination that is quintessential of the luxury SUV with a penchant for aggressive behavior.
