what the mil deletes do is plug into where you o2 usually would the the other end plugs into your o2 then threads into your h pipe/ x pipe

Without cats, your rear O2 sensors are going to think your car is running rich. In turn, it will pull out fuel, causing you to run lean. We all know what that leads to.

I thought that's what the front O2's do, the rear ones only measure how efficent your cats are working. Let me know if i'm wrong.

Well, all four work together to measure A/F and temp. The rear two are judging effective/defective cats as well based on the change between the upstream and downstream sensors.
