O2 housing removal

[emoguitarboy]

Hey guys, I asked in another thread (didn't get much response) and I'd search but "O2" is not a valid search phrase.

What is the easiest way to remove the O2 housing while the turbo is in the car?

I need to remove mine to put up the turbo to cat 3" down pipe on.

I removed the a/c fan and unbolted the downpipe, 3 out of the 4 bolts were easy to take off but the one near the block was a pain in the ass.
