How to delete CAT without codes getting thrown

Was wondering what you have to do after removing the cats so no engine codes get thrown. Could I plug in an OBD2 controller and clear it that way? Any help would be awesome, Thanks!

I prefer not to respond to your posts, but I must here. I doubt there is any way, but I suggest no one answer this substantively. it is illegal under federal law to remove or tamper with a vehicle's catalytic converter if the vehicle was originally equipped with one. This is mandated by the Clean Air Act, and violating it can lead to substantial fines and penalties for individuals and repair shops alike. I suspect this forum has a rule against helping to do anything like that. Please do not ask for help to achieve actions that are illegal. If I am wrong, my apologies in advance. I am not a lawyer.
