I think a single bike trailer could hold hundreds of dollars of stolen scrap metal and cc's. And there is no need to 'break down' the scrap metal. A CC is all one piece and costs a thousand or more to replace, and can fetch a few hundred from a salvage yard.
The profit is quite high:
"A catalytic converter is an essential emissions control part and is a key component inspected during a Smog Check. It contains rare metals responsible for converting smog-causing pollutants that pass through a vehicle’s exhaust system into less harmful compounds. Because these metals have a high recycle value, catalytic converter theft has become increasingly common.
Experienced thieves can remove a catalytic converter in one to two minutes using basic tools. What can net a thief hundreds of dollars at a scrapyard or recycler can then cost you thousands of dollars to replace, depending on the make and model of your vehicle. Learn more below on how you can protect your catalytic converter and prepare for your vehicle’s next Smog Check."
