Cat delete and O2 sensor work around?

[HeliMatt]

Hi all,
I have a 96' yukon and I'm thinking about deleting the catalytic converters with a custom exhaust. My question is has anyone done a cat delete, will that affect the upstream O2 sensors, and is there a way to work around the downstream O2 sensors throwing a code? I've seen the spark plug anti-fouler method. Has anyone tried that and does that work, or is it better to tune them out?

My cats are long gone on my 98 K2500 and the O2 sensors are all still there, no codes ever set. Didn't do anything to it, your results may vary.
