Engine swap help

When removing your engine did you disconnect the exhaust at the point the headers meet the exhaust or disconnect the exhaust manifold at the engine?

Were stuck between how to do this. I say we should disconnect it at the end of the headers, but the guy helping me says that might not be possible without torching the nuts. Said when he tried to undo them on his e34 the only option was to torch a couple bolts.

Please share what you did, tips, tricks, insight, anything.
