headers, what all do i need?
i have a 2001 trans am, with a borla cat-bak right now, i want to get headers, but im not sure as of to what all i need to make sure it all bolts up? do i need a new y-pipe or cats or is there anything im missing?( i tried searching but couldnt find what im looking for), the only thing i did find was that i should stay with shorties if i want to stay smog legal, do i gain any power or at least a good sound with shorties?
