IIRC all (most?) "cat-backs" for our cars are really flex-backs, starting after the flex pipe.

Yeah, the exhaust will bolt up to the flex pipe.

I'm kind of in the same boat....I'm taking the SVT exhaust I have laying around and putting it on my wife's ZX3. I know they are different sizes, but that is something that the muffler shop can worry about....actually, now that I think about it, I could do it at work. We have a welder and sawzaw.
