Cat delete

[Automotive Innovations]

What would need to be adjusted as far as parameters go when a cat is removed on a vortec 4200?

I believe you delete the o2 sensors after the cats. I think you do that in engine diagnostocs dtc mil. No mil for bank 1 sensor 2 and bank 2 sensor 2.

And disable cat protection.
