Hi, there new to the forum, I just picked up a 2003 gtp and it has a broken motor mount, which intern cracked the rear manifold, I live in Albuquerque New mexico and they have emissions here, so I will need to be running a cat. I figure that since i will be changing out the rear manifold I mine as well install a set of headers. So for the real question is there a set of headers on the market that retains the current down pipe? Most of the headers I have seen come with a new down pipe and what seems like a diffrent connection set up then the factory manifold.
Thank you for any advice or ideas![]()
