Unfortunately the catalytic converter's executive order (EO) and model number must be visible in order for it to pass the smog test. There is no other method of retrieving the CAT numbers except from the catalytic converter directly. Having the number(s) scraped off technically renders the catalytic converter as "tampered"; automatically causing the inspection to fail.
Without the CAT numbers visible a smog technician has no way of verifying whether or not the catalytic converter was designed to be used on your vehicle. As such, the vehicle can not pass a smog check. To remedy the matter, you'll be required to purchase and install a California Air Resources Board (CARB) approved catalytic converter designed for your vehicle's year, make, and model. The CAT may an aftermarket or original from the vehicle's manufacturer. More then likely you will spend much less with an aftermarket OEM approved catalytic converter.
