i know its not true but im starting to believe that all 02+ GT's came w/ Flowmasters Welded in... every one that i have seen lately that was "stock" has had weld in flows.
now that i have the stupid statement/question out of the way... how retrictive is the stock Catback and what size is it? should i get a midpipe before i change my catback as it has already had the mufflers replaced? and how does the MAC Prochamber compare to other midpipes.
