Codes

My Service Engine Soon light came on and I took it the local auto parts store. The 0420 and 0430 codes came up. From what I read its the catalytic converter. With those codes, does that mean both converters on the headers went bad?

Cats are welded to exhaust manifolds. May need to go with new exhaust headers, b-pipes, and uprev. This is WAY cheaper than buying OEM exhaust manifolds at $1,200 per side (part only).
