Whats the best way to get this fitting off

Cut it pie shaped and bend the "slices" in. Soak it with a mix of acetone/trans fluid.

I had to take an open hack saw blade and carefully cut a slit in the pipe. When it gets really close to getting all the way through, you can squish it with a pair of pliers and it will come out easily. Oh yeah, penetrating oil doesn't hurt.

You can speed up the process by using a cut off wheel or saws all for the portion of fitting that sticks out of the manifold.

You guys beat me to it. I cut mine into two pieces with a loose hack saw blade, being very careful not to cut too deep. Then I tapped the top towards the cents like Steve said, added some penetrant, let soak for a while, more tapping, more penetrant... It took about an hour. The treads were fine.
