At a loss trying to remove exhaust bolts

[Htci]

I just did this repair recently. I left the broken end protruding and put a socket on the other side then used my bench vise to compress the broken end into the socket. I just applied about 20lbs of force and heated w a run of the mill propane torch around the flange and within 20 seconds the bolt POPPED into the socket. Now that you’ve ground down the broken end flush you’ll need to find some scrap metal to force the remainder through.
