986 S exhaust troubles

[rfuerst911sc]

What kind of torch are you using ? At a minimum use Mapp gas but preferably oxy acetylene . Get the nuts/bolts cherry red and then slowly loosen . Between heating cycles hit with kroil or PB Blaster . Go slow and methodical and you shouldn't break anything .

Oxy/acetylene, pro setup. there is no substitute for this since a map gas torch isnt hot enough... and I'm no newbie on this. I have never had bolts not come loose, never had them shear off but not come loose.
this is ridiculous.
one sheared off, cannot extract the stud, the other came loose (the nut) but can't remove the stud and the other is welded in, everything is rotted off on one side and will not come out. the entire flange is stuck and wont come loose.

I am considering cutting this thing off, but I will still have pieces of the flange that could just be hopelessly rusted together.
Never, never, never saw anything like this before in my life.
