I bought a Dr. Gas X-pipe for my BBK longtubes and tried to install it, and there was no way in hell it was going to fit. So I call up Dr. Gas and ask them about it and the guy says you have to trim fit the front pipes off of the header. So I did this and it only made it worse. I cut little bit by bit off each side to try and keep the X in the middle of the car, well that won't happen. I am just wanting to see if anyone else has had this problem. Thanks guys.. Ricky.
