pesky O2 sensors
my stock O2 sensors are stuck in there and I cant get them off to save my life. I borrowed a o2 socket set from the parts store, and drove around to pre-heat the pipes. I even tried PB blaster, which I dont think would do anything anyways, just for good measure. Any other tricks that you would recommend?

Try heating the local part of the pipe with a torch, that way the outside should expand before the insert and give you a better chance.
