Might be getting a C5, have some questions.
As far as exhaust, an aftermarket system will pick up over a standard C5 exhaust but not much over the stock ZO6 Ti system. If at all possible try to track down some local owners and listen to them in person.... if you can squeeze in a short ride because some sound great on the outside but will kill your ears on the inside.
Before performance mods I'd recommend a skip shift eliminator and especially a column lock bypass. And yes, vette guys port their throttle bodies.
