Application Notes:
Description:
Dinan free flow axle-back 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 computer controlled valves that limit noise during low speed driving and open fully during high-load conditions to allow free flow. The exhaust gasses exit through larger laser engraved black ceramic quad tips. Every Dinan product is designed and tested in Morgan Hill, California.
