Great product. Nice throaty sound from the motor and exhaust. Works well paired with my diablosport and I suggest you modify your factory airbox for Max performance!

Not enough time to prove mileage gains but no question the improved sound when I step on the gas. The installation was clear and easy to perform. Response does have an improved feel and definitely no buyers remorse.
