Dinan Free Flow Axle-Back Exhaust - 2009-2015 BMW 750i/750li
Dinan's Free Flow Axle-Back Exhaust improves 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 harder acceleration with zero drone. 100% stainless steel construction and exacting specifications ensure that the system fits correctly using the factory hangers and will resist corrosion for years to come. A vacuum controlled butterfly valve is utilized to improve flow at wide-open throttle while keeping things civilized and 'drone' free throughout. The design reduces overall weight as well and ships without tips so that it may attach to the stock tips giving a stock look.
