If you don't plan on keeping the old stocker midpipe around to sell, or eventually reinstall, I'd cut it on the passenger side, and drop as much all at once. I only had a small piece to unbolt from the cramped passenger side, and it seemed to make it a bit easier to deal with. Also, I used a nice impact-grade swivel, which doesn't bind up on certain angles like your typical cheapy swivel does. It doesn't have crazy joints or anything; it's all smooth motion. Soaking the bolt a day in advance, and doing a little driving first helps, and then re-soaking it when you do the removal. Do it when it's a bit warm, like 20 minutes after a small drive. If you're not 100% sure that socket is all the way on the flange nut, don't try to turn it at all! I've heard too many stripped nut stories on this side, and they are no fun. If worst comes to worst, there are the stripped bolt remover sockets you can get. Good luck with this, especially if you don't have a lift. Get it up as high as you can, safely!
