I did the Hi performance kit and ****** happy with the results It has more torque and it screams from 6000 up. I am running k&n's. Had to put a new clutch in right away. Stock clutch could not handle it. Has a deeper sound. Carlos told me I would get 10 hp from this. I do not have dynos to back up anything. but a big difference
