It will be super loud if you had some LT's. I put some Pacesetter LT's and ORY with borla adjustable exhaust thing sounded so loud with the cut out open i had to completely close the block plate for the exhaust. I'm looking to get a LT ypipe that has high flow cats to help with the sound.

Knowing what I know now about the process and the gains, I wouldn't do it again. If you are really worried about maximizing the potential, put some hi-flow's on there and forget about it. At best, they may give you a slight edge over stockers but it's doubtful. I've got to go with AdamSS on this one. Small, if any, power gains and please don't expect to feel it when you get on it because you wont.
