P0420 (M) 1/1 Catalytic Converter Efficiency Catalyst 1/1 efficiency below required level.
and besides destroying the ozone should i worry about it or erase it.

it wont erase, it will come back. all that means is you need a new cat. and you wont pass emissions. look in our vendor area they sell a VERY nice cat for a good price

X2 that usually means the cat is no good. Just replace it and you should be good to go.
But before I condemn the cat I aways check for exaust leaks around it first. That can also throw a code.
