I need to remove an old pipe and need ideas as to how to remove it.

The 50-year-old 2-inch diameter threaded galvanized pipe that
horizontally protrudes about a half inch from the cabinet under the
kitchen sink is leaking where it meets the 10-year-old plastic pipes that
drain the kitchen sinks and garbage disposal unit.

The threads are all screwed up so I want to replace the nipple.

I can only see the last 1/2 inch of that threaded nipple but it appears
to go through the 3/4" thick kitchen cabinet into the wall about two
inches (or so) and into a T fitting where the vertical up pipe goes to a
vent on the roof while the vertical down pipe goes to the crawlspace
drain pipes.

The problem is how best to remove the four-inch long (I assume) nipple
when only 1/2" of it sticks out of the cabinet attached to the wall.

One option, of course, is to rip out the cabinet, but, that's a LOT of
work to replace a two-dollar four-inch-ling two-inch-wide nipple!

Is there an easier way to get the 50-year-old nipple out?
How about just cleaning it up and epoxying a fitting to it to take
the plastic????
Chances of removing it without doing further damage inside the wall
are remote, at best.
