I assumed that the light would eventually come on again with the same error code, that is why I purchased the code reader. As far as the second cat burning out, If I were to purchase a high flow cat, would that take care of it? Or would the same thing happen again? Also, how would I trick the sensor?

removing one of your two cats reduces the exhaust gas filtering which is why the CEL is coming on. getting a high flow cat is a step in the wrong direction.

to trick the O2 sensor you could try something to pull the O2 sensor further from the exhaust gases. I am planning on doing this trick with my exhaust after I turbo since I will be removing the cat and going straight pipe. I am not sure if it will work but it's worth a try.

this example is from the Subaru guys [I think]. They used spark plug non-foulers from the Help! section at Autozone. I can't find the original post from it but I did save the picture...
