How do you remove V band from exhaust?

I've backed the nut off, soaked it in PB blaster, hit it with a hammer, am I missing something?? It will spin on the exhaust but will not loosen up.

I'm trying to get to the starter, because of course it goes out right before the Fourth

I got it! Needed a BFH
