I have been researching this question as well. There are a bunch of exhaust threads you can do a search on. The impression I get is that all performance mufflers will improve performance slightly and some increase noise significantly. Flowmaster has several choices. Go to their website, they have a graph that compares their different mufflers.

Thanks
Thanks
Not a catback, just muffler swap.
I didn't notice any SOP difference, but it sounds real sweet.
I've got a vid of me doing the seafoam treatment.

A lot of the stock Vette mufflers were dynomax brand, which make cheap performance mufflers. you won't see much difference, but it will sound a lot better, you will see some difference if you open other things up like gutting/removing the cat (if you live in a town with no inspections)...
