[TR] Detaching header from tailpipe

[Lee&John Howard]

Hi

I've got everything out of the engine bay and have been in there with wire
brush and simple green. Dirty work, but there are those who love it.

I'd like to get the header out for a ceramic coating, but, of course, can't
budge it from its junction with the tail pipe. Many applications of
rust-bust stuff hasn't helped. Is there a way to get them apart without
cutting? Do I apply a  propane torch?

Many thanks
