anyone with a zx6r fuel injection model, get slip on and a powercommander. I bought a full akrapovic system I gained hp and sound, looked good but lost too much torque for street use. its a race only application due to the larger headers. go with the slip on i am going back now to stock headers and slip on

anytime you put a full exhaust on you NEED a power commander on a FI bike...plain and simple
