6.7 P2032 Hi temp exh sensor fail

[AmWanderlust]

OK got this error on I80 and it threw the truck into limp mode. I know that it is a failed sensor number 2 but I have been have a heck of a time getting it out. One YT video warns about excessive force wringing the sensor off and the guy uses 5 days of PB blaster and a 13 mm combo wrench to get it out. I've had 3 days of PB blaster, heat from a MAPP torch and the sensor will not budge. Snapped off one side of a HF 13mm wrench.
Another YT guy jumps straight to a 13mm socket and breaker bar, says to use heat if rusty/corroded from road salt. Mine is clean having spent all it's winters in FL.

So what to do? I'm about to use the breaker bar carefully. The sensor is steel but the exh. header is stainless thus gauling issues too. I have the right size tap to clean out the hole.
Now if I can get the @#!% connecter to let go.

I think this is one of those times when a bigger hammer may not be the way to go. Can you get a drill on it and drill it out but stepping up in bit sizes. Just a suggestion.
