exhaust size
I have a 2002 coupe with a vararam air filter. I would like to put on lg headers, hi frow cats, x-pipe, and borla stingers. I"ve read that the headers back thru the x-pipe can be gotten in 2 3/4 or 3 inch sizes. I would like to go the 3 inch route in case I magnacharge later on. My first purchase will be catbacks. The question is, do catbacks like the stinger come in a 3 inch size, if not, does it matter. At what point would the dia. be reduced

You can get 3"everything for the C5 exhaust. Hi flo cats, X pipes, extensions, tail pipes, and mufflers. I went with the RT hi-flo cats and exhaust system from SS Works. Added 3" Magnaflow mufflers.
