sub oxygen sensor

i replaced my oxygen sensor, and my gas mileage improved a hell of a lot. i also have a sub oxygen sensor, but the tsrm says dont mess with it unless you get error code 27. should i inspect it anyway?

also, if i was to remove my cat, how would that affect the sub oxygen sensor and/or ecu?
