Answer
If your catalytic converter is melted and blocking the exhaust, it will prevent the engine from running correctly and may damage other exhaust components.

If the catalyst is melted away and the exhaust is not blocked, there are two minor consequences:
1.  Your exhaust will have excessive hydrocarbon and CO emissions.
2.  Your check engine lamp may come on.
