Help with stuck O2 sensor

In the midst of swapping out my x-pipe and having trouble with the front O2 sensors. I was able to separate/unclip the rear sensors but having trouble separating the fronts (probably being too cautious, just don't want to break the them.) That led me to try and unscrew the sensor from the pipe (working under the car on stands so hard to get a lot of leverage) and seems to be locked solid. I don't have a torch handy, any trick to breaking these loose? Or any tip to separating the front sensor clip? Thanks.
