Well, with that in mind what kind of exhaust setup are you trying to run. I see you want 3" but are you running a high flow cat... test pipe...
Just to let you know, exhaust shops will not work on your car if it doesn't have a catalytic converter. Been there... I had a 2.5" Testpipe on 2 1g's I've owned. So your best bet if you want 3" is to get a cat-back system down in 3" or simply buy one. Having one made is somewhat cheaper. Get a 3" Testpipe or High Flow Cat if you prefer. Saw your looking into a 3" downpipe get that as well.
