Well after my last posted thread I think I've decided to go with long tube headers. My ? is will long tube headers connect to this custom h-pipe www.v6mustangstuff.com/Exhaust.html cause im gettin it along with the gt take off exhaust for christmas. I was goin for that setup just so its not to much money. Would i be able to keep my old cats or would i have to by a h-pipe with catylitic converter?
