if it is really stuck on there you have two options: keep trying with a bunch of extensions or drop the y pipe. I heard alot of people remove it with taking nothing out?

The dealer is always ready to ream you if you want motivation...
I am sure you will get;)

Can you get a rachet on it? I mean if you know that it's bad then cut the wires and get a deep socket 7/8th on the thing.....They also make a special socket that is made for O2 sensors....maybe that will help...
