Cat delete: What todo with cat 02 Sensor?
 
So, If I install headers the delete 02, or install Cats that delete 02 what do you do with the electrical sensor?

unless tuned for it, you will need to free-air the sensor. Just tie them up and out of the way.

I am thinking of deleting only 2; either the rear or the header cats, but not all 4 in order to remain emission compliant

In that case I would delete the front cats. If you buy headers with O2 bungs it will help get the most accurate air/fuel mixture. I have a O2 sensor extender kit I made when I had headers on mine.

That is helpful; what is an 02 bung?

The threaded hole that you install the sensor into.
