How do I handle the 02 sensors?

Are you wanting to eliminate all 4 of them or just the downstream ones?
I am assuming all four of them if I'm not gonna be going back on with the catalytic converters I didn't I don't know if you still could use downstream ones or not on the headers I haven't gotten quite that far along with it yet but that's my next step with the jeep down that I got the fan the belt figured out

I'm almost 100% certain that you'll have to have the upstream 02's or the engine won't run. The down stream ones if you delete your Cats you'll have to weld in a o2 Bung in each location close to where the Factory ones were/are. Then use a O2 Fooler so that the ECM still thinks the Cats are still there, these are the ones I used for my high flow Cats.
