Hello Ryan and thank you for submitting this question. There are times when truly a smog check station nor dealer service center can assist with an emissions issue... for that, the State of California has locations referred to as Smog Check Referee Centers. They are usually located at local community colleges.
In this specific case it is our recommendation to make an appointment with a smog check referee and allow them to inspect your Honda Accord. Upon their determination that the catalytic converter is defective and it is the only cause for the vehicle's emission failure, AND if they are unable to locate a replacement CAT, they can issue you a smog check exemption. More than often however the needed emission component is found, and they will help find it.
You may make a referee appointment by calling (800) 622-7733. We hope this information is helpful to you.
