P0433 Heated Catalyst Efficiency Below Threshold (Bank 2)

Any body ever have a P0433 code? I searched the forums and a quick
Google search, but it doesn't seem to be very common.

The truck is a 2000 QC 4.7L 5spd with 184,000 km (~110,000 miles).

Dealer reported recently that I have a broken exhaust manifold stud.
Could that be related to this code?

Thanks in advance for any help.

Rob S.
