And by the way, you can blow up your engine just as easy with that Procharger.

Regarding your mufflers, in theory by removing them you will gain a few hp in upper rpm's (just a few that you'll probably never feel), but the reduction of back pressure is gonna cost you some lower rpm torque (which you will most likely feel).
