I don't want someone to put razor wire on their catalytic converters so that it slices thieves' fingers off. I do, however, wish to leave the impression with thieves that perhaps my catalytic converter is protected by insanity armor.
When I lived in California I wrapped a bunch of chain around the cat on my truck. Wasn't actually that secure but thieves see a ton of chain and padlocks and go "ehhhh keep moving."
Off topic, but I was very pleased with how easy a catalytic converter shield was to install on my car. It’s normally sold and installed by a dealer, but if you have any semblance of DIY skill it’s straightforward.
