As for the back 2 sensors, you could either get a custom catted y-pipe to keep cats on the car, or just get a set of sims that will trick the computer into thinking the cats are working fine.
Depending on the emissions testing in your area, it would probably be best to keep the cats on the car , even if you still had to install the simulators. The 2 rear sensors don't really "do" anything anyways, besides tell the computer that the cats are working efficiently.
