Hmm, well that's three of us hitting the crossmember now, and your exhaust is all stock other than the catback right? The exhaust genius that fixed mine in the other thread, this is basically what he ended up doing (in case you want someone to do the same):
Basically he jacked the exhaust up into the correct place from the front (the Y-pipe), ignoring the rear bumping up into suspension stuff for the moment, then used a torch to heat the two sides of the Y-pipe (about where that one slip join is on one side) and then pulled on the pipes while they were red-hot to get a very slight upwards angle there. Then he left that supported on its jack, went to the very rear (back by the two slip joints just before the muffler), and again heated both pipes red hot all around, and pulled down a bit to get them well clear of the suspension stuff. That made things "better", but it still hit the crossmember when the jacks came down.
Then he kinda had an "ah-hah" moment, and heated up the Y-pipe section right by the big flange that connects it to the rear (like maybe 3-5 inches forward from the flange), and apparently that's where all the misfit tension was. He didn't even move that one, he just heated it up (with the jacks in place) and it corrected itself at that spot (the pipe now basically shifts up (without changing overall angle) some fraction of an inch right there, so that the rear is higher than the front).
