O2 sensors

Will be swapping out my connection pipes for catless in the next few days. Anything special I need to know about removing/installing O2 sensors?

Nothing other then don't be surprised if they are crossed threaded and you can't get one or both out. When reinstalling them be sure to but some anti seize on the threads.

Spray the rear ones with Kroil, Knocker loose or eqiv. Let soak for 15 minutes and remove. Since you have had out for header install you should not have any issues.

Seems to be hit or miss. I have taken mine out a couple of times and they come off and go on easily. Other people have such a hard time with one or both.

I did not read his post real well. Should have no problems with getting them out.
