Got an engine light and a P0106 Code. Mechanic addresses the manifold issue but engine light is still on now with P0420 and a P0430 (Catalytic system Efficiency Below threshold)

I got the first code addressed within a day or so of the engine light coming on and mechanic thinks the first issue may have tripped something giving me the new codes for the Catalytic Converter. Do I just have to assume the Cat is bad at this point?

Thanks in Advance.
