I have a 2006 mustang gt and i just bought a slightly used magnaflow x-pipe off of someone that had it on their gt500. I am now having a hard time getting it to work on my car. When i bolt it up to my headers the rear part of the x-pipe hangs low and doesnt want to connect up to the two clamps. Is the x-pipe i bought made specifically for a gt500 or should it work on my car? anyone have and advice on what i should do?
