Re: 2001 Exhaust replacement
Don't bother with PB Blaster or Kroil or anything like that, use a torch to get the nut hot and then try again. The heat will expand the nut, breaking whatever bond has occurred between it and the bolt.
Having taken off more than my fair share of rusted bolts/nuts any time you can use heat, do it. If you can't use heat, use Kroil. Oddly enough, when I was in the USAF the guys in the jet engine shop used plain hydraulic fluid.
Good luck and watch your knuckles.
