Exhaust stud broken at pipe

These things really rust up. I suppose this is a pretty regular problem. I've been soaking it with PB and putting vice grips on it but no luck extracting yet. Just more soaking???

If you can try using a file to flatten out two sides of it. That will give you something more to grab on to. Also when you have the vice grips on try tapping the stud with a hammer. Vibration is really helpful for loosening thing up.

If there is nothing delicate around it, blast it with a propane torch. Then vise it and crank.

I have an extractor set but it seems to be between two sizes. It's really on there too.
I'm building highway pegs per Wolfies design. I got them set up how I want them but now I new to fix this.

Go with the smaller of the two sizes? I'm a fan of torching, blasting with pb, tapping with a hammer, and cranking

I'm a bit worried about hitting it with a torch with all the plastic and wiring in the area.

I've never had to torch an exhaust stud. Most of the time a few hammer swings does just fine.
