Cost to replace catalytic converter

My check engine light is on and the OBD reads error code P0430. Looks like one of the catalytic converters is gone. How much is the replacement going to cost?

P0430 = Catalyst Efficiency Bank 2

Start by checking the "Possible Causes" listed below. Visually inspect the related wiring harness and connectors.
Check for damaged components and look for broken, bent, pushed out, or corroded connectors pins.

Possible Causes: and relative expense for parts and labor
Dirty Air Filter (check / clean or replace) $
Exhaust Tube $
Intake Air Leaks $$
Faulty Oxygen (O2) Sensor $
Faulty Fuel injector(s) $$
Leaking Fuel Injector(s) $$
Faulty spark plugs $
Improper Ignition Timing $$
Faulty Engine Control Module (ECM) $$$
Faulty Three-way Catalyst Converter Bank 2 $$

Be sure to fully test and diagnose the root cause before replacing any parts.
