I have a buddy who bought the SLP catback and X pipe for his 01 GT. He went and installed the cat back with no problem, but when he tried to bolt up the X-pipe he discovered that on the driver's side the flange that hooks up to the headers doesn't fit right. The connection isn't snug and leaves like a half inch gap where the stock bolt on the manifold connects to the X-pipe. Did any of you guys have this problem? How did you fix it?
Sorry if my descriptions are poor I haven't seen the problem, so I am just trying to describe the problem from what he told me.
