Catalytic Converter Skid Plate for a third gen?

Anyone know a good skid plate for the catalytic converter? I've been told that the cat being original means it isn't as valuable. But I don't expect a fucking worthless, waste of air, scummy, low life, piece of shit crack head to know their head from their ass, or a less valuable dirty catalytic converter (like mine) from a more valuable clean catalytic converter.

So I want to be proactive and deny them the chance to screw up my emission system by blocking them with a skid plate. The skid plate doesn't have to cover all that much, just the catalytic converter.
