Dinan engineers designed the BMW 750i 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. 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. Like all Dinan exhausts, our 750i 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. In fact, on the G11/G12 750i equipped with a Dinan exhaust you will be amazed at how deafly quiet it is in the cabin. That is quickly changed however when exiting the vehicle and being witness to the big luxury sedan passing you by at full load. In that moment the jaw will be agape and you will swear something more akin to a classic V8 muscle car?had passed you by. It is the perfect blend of tame sophistication and raucous performance for a stately sedan such as the 750i.? ?
The system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. While the sound is surprising at full load perhaps even more surprising is the system fully embraces the sleeper mentality. Without hearing it you would never know an aftermarket exhaust was on the vehicle as the design utilizes the stock cutouts in the rear bumper and not aftermarket tips which leave the elegant and seamless styling?of the sedan intact.?
