I once had the pipe out and was banging and banging with a mini-sledge to
get it off. The male threads welded themselves to the female threads on
the
manifold. Luckily that manifold was junk to me. I didn't try to clean
the
threads with a tap because I had a used one to replace it with.
You're better trying to remove it while the manifold is still on the car,
and then use a l o n g pipe as a breaker bar - if necessary - it's
smooth
and works.
Oh yes- soak it with penetrating oil...
