Hmm. If your state doesn’t require vehicle emission tests (aka Florida) is there any reason to steal the converter ??

Of course there's reason to steal them. What a vehicle owner does in such a state after the convertor is stolen is the 'Hmm'.

They're at least going to have to do something about the vehicle being loud as hell.

Up to 30 grams of platinum group metals.

Thieves will steal them because they can be resold. I like the idea of etching the VIN on them, but would go one step further...make sure the thieves get suitable punishment they would remember if they ever get ideas about repeating the offense. Laws of certain countries would possibly call for removal of a hand for theft. That would at least slow a thief down, possibly long enough to get caught in the act. There are other possibilities if LE wanted to get more creative.

They steal the converter to sell for filthy Lucre. Maybe you meant to ask the question, why replace the CC with another. Put a straight pipe on it. I know this is what I have done in the past, but newer cars need that back pressure to run correctly. Computers and such make this a must.
