I had this very same exact problem last summer. Same exhaust stud. I ended up throwing an old A/C compressor across my front yard I was so pissed off.
You should remove the radiator, power steering pump, as well as the power steering bracket. I was able to get a 90* bend for a drill from a friend in order to wedge into that spot. It probably took me half a day to get that one stud out. I always used the drill, then extractor method. It has worked, but only after plenty of headaches.
Good luck, I know it sucks.
Here is an example of the 90* piece for the drill.
