The Texas Unauthorized Possession of a Catalytic Converter law gives police the right to arrest you if they believe you possesed a catalytic converter that was removed from a car that wasn’t yours and you didn’t come to possess that catalytic converter in the normal course of your business.

The legislature passed this law in 2023. I think this law will have some difficulty in enforcement due to the fact that it seems easy to subvert. Anyone having a possession of a catalytic converter would claim that they came in possession of it through the course of their business.
