So after getting her running I heard a rattle and got under the truck to see if I could find where it was coming from. Rattle is coming from the cat, and the exhaust is starting to get a sour smell to it. So.... time to replace the cat, any recommendations on a cheap one? there are no emissions checks in louisiana.

Don't do the non-fouler trick on the front O2. You WANT that one to get an accurate read on the exhaust stream.
Non-fouler trick for the rear O2, is to fool the PCM into thinking the cat is still there, so, it won't set codes, or, adjust fuel trims in a vain attempt to heat up a cat that isn't there.... in order to get the numbers where it expects them to be.
