The F10 M5 is one of the most powerful M-cars ever to leave Munich and we have the high performance exhaust solution to give this super-sedan an even more aggressive tone
Dinan’s Free Flow exhaust system features 100% stainless steel construction measured to exact specifications to ensure proper fit via factory hangers and mounting points. Dyno tuned for maximum exhaust flow with minimum backpressure, this system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to Dinan’s exclusive Helmholtz Chamber and Butterfly Valve technologies. The exhaust gasses exit through larger laser engraved ultra durable satin black ceramic coated quad tips.
Every Dinan® product comes with our industry exclusive factory matching new car bumper to bumper warranty and is designed and tested in Morgan Hill, California and can be purchased and installed at any Dinan Approved BMW dealership nationwide.
