all i have to say is that its perfect! not too loud, but u know that its deff. there. really low, throaty sound. and it looks great!.....the tip sticks out just a little farther that the stock bumper so u dont have any of the carbon buildup on the back. i noticed a smoother pick up through the rpm range and better low end torque. and it was really easy to install (took me 40 mins from opening the box) two bolts and 4 rubber hanger and the stocker was off, and 4 more bolts and 4 hangers and the evo was on.....all in all :bowdown: ---> GREDDY EVO.
