P0420 is a common cat efficiency code. Did you use a nonfouler along with the stock sensor? Again year make and model also brand of header are you using. That info would sure help

P0420 is BANK 1 catalytic converter, your o2 sensor after your converter is picking up fumes that have not been cleaned by the catalytic converter...meaning your whole catalytic converter is no longer effective and needs to be replaced (only if you need to do an emissions exam for your car)
Im gonna take a wild guess and say p0430 is BANK 2, so both your first and second catalytic converters arnt doing there jobs
I highly doubt they both went out the same time so im going to say remove whatever you installed and see if the codes go after driving it around
