What is litre size of engine? I looked at 5.0L. Only one 02 sensor and that is before the cat. With the forward 02 sensor, the cat shouldnt have anything to do with the front 02 sensor.

If you live in a state that does vehicle inspections, it wont pass without a cat.

Just to add, if no 02 sensor in exhaust. You can get a bung ring, cut small hole in exhaust pipe. Weld bung ring over the hole. Screw in 02 sensor, wire it up.
