Default CEL Code delete from 00 ECU possible?

Ever since I replaced both my O2 sensors my Legacy keeps throwing the P0420 Cat Inefficiency CEL. Ive tried clearing it and letting it slide, Ive got the Spark Plug spacer mod down there, it keeps coming back.

The stock cat is still there, but at 106k miles, its probably shot. Getting another cat is not something I have the money to do.

Can I delete the code from my ECU? If not, what can I do?
