Im gonna get the hookerheaders shorty comp, it comes with a y-pipe and is meant for single cats, for some reason I have no clue my car has dual cats, I think the person before me moded the crap out of the car and put dual cats on, anyways I have the hookerheaders cat-back and a muffler place is installing it, I e-mailed holley and they said go for the 2055 but im gonna have to either mod my y-pipe to fit the headers or convert to single cat, I have no automotive skills and im gonna be broke real soon, I would like to mod my exsisting y-pipe but also its old and prolly restritive how hard would it be to convert to single highflow cat, what would be the draw backs, and whould I have to weld, would I be better off buying the headers and just taking it to a place and have them do it? any help would be great
