I have 8 days to pass smog in Nevada, I currently failed one smog test already. I had Berk test pipes. Today I just put back in my stock cats and I'm still getting a o2 sensor error, when inspecting my sensors their tips are black, not sure if I've burnt them with having a straight pipe and now are defective.

Does anyone have any recommendations on something I should do before buying new ones?

You could have an exhaust leak, masking itself as a bad o2 sensor. I have the same. Replaced all of the o2 sensors and still get the o2 bank errors. Even after all resets/relearns/code erases. I SUSPECT, that the leak might be coming from where the HFC's bolt up to the manifolds. I'm just too lazy to redo all the gaskets without a lift.

My CEL intermittently goes off for a short window of a few weeks, but comes back on most of the time. I've been dealing with this for years, so whenever the light goes off on its own, thats when I take it for inspection lol...

I also have BERKS and Borla TD.

Did you have the extended O2 bungs on your Berk test pipes??

Sorry I didn't know I double posted, and travlee you can eat my ***.

Thanks Jerz & Atreyu I didn't have spaces on until about a week ago so I ran my car without them for about 7 months.

Then you probably did fry your O2 sensors.
