I agree with Silver on the size. You said this is going to be a show car right? So show, no go? If so, 2 1/4" to the y-pipe, then 2" back would be better. 2 1/2 may be too big for a car with no mods done. Either way you'll be fine though.
On a side note, make sure your mufflers are actually hanging properly. That's the thing that pisses me off the most is when people spend money to have duals, and then they're all cock-eyed and falling off. Lame.

The only Mods I have is the 4-1 header and a CAI. But yea its just a car that'll turn a few heads. But I don't want to be moving in slow motion either. I just wanna get a heads up on how much power i'm looking to lose here and when am I'm going to suffer the most (low RPMS or high RPMS??). And if i'm going pay my hard earned $$$ to have this done, I'm gonna make sure it looks decent.
