My exhaust isn't the best fitment either. I also did have a bit of a problem with the cross member touching the x-pipe. The quality of the exhaust is great but the fitment is not perfect.
I placed a piece of old exhaust rubber hanger between the exhaust and cross member handled that issuee well. I tweaked the piping to get as close to where I wanted with the fitment and it's better now but not perfect. Here is a pic.
