My son put long tube headers on his truck a few months ago, complete with proper Y pipe, and full 3" to the back. 
 

He sold the stock cats and it paid for everything.

Good point. Got the CCM Level 2 version installed on  our '09 Prius in February. It looks to me like the front and rear brackets would provide enough of a  deterrent against cutting out the upstream cat. Am I missing something?

I have to figure out what this means in cat prices.  I still own 3 Prius but I have no emissions testing. 

I wonder if I can pull out my old but factory cats, replace with aftermarket, and still turn a hefty profit

I have a friend here local that does just that. Buys Prius, takes of factory cat, installs $125 eBay one and sells car for what he paid-makes all the money off the convertor.

Since I drive a Honda Element which is a super high cat theft risk I went ahead and ordered an elaborate cat shield a few days ago. I've been pushing my luck for a while and it's made me paranoid when I park it somewhere. My Element is  keeper so I consider it an investment.

My daughter drives a CRV and parks it in dorm parking lot at her big city college. It's just a matter of time on that one. But teenage daughter who doesn't really seem to take care of her stuff very much I'm not compelled to put 350 dollars worth of cat shield on her car since I have no idea when or how that car will meet its demise. 

Bringing this thread back up to quote myself. About one month after I wrote this I get "the call" from Bailey. "Car's making loud noise when I started it". The campus police reviewed the camera footage. The police slow rolled the parking row and the thieves were creeping one row behind him. As soon as the police turned the end of the row they hit her car. Less than 1 minute start to finish to get her converter. Campus police said one or two cars per day have been getting hit. Mainly Prius's but also CRVs. It's a very large campus with much sprawl so the thieves have an advantage.

So, like I had alluded to, my daughter does not care for her cars as well as I'd like so I am hesitant to invest much into her CRV. I wound up buying a dirt cheap converter from Amazon for 140 bucks. Two new O2 sensors, and a Walker brand midpipe which they cut. All in, about 400 bucks to replace it. The sensors were 180 of that. I had to Amazon everything since their delivery is more predicable than Rockauto and I was under a time crunch to get her mobile again.

The Chinese converter is satisfying the check engine light so far. It sure looks like a dinky piece of E36 M3 when you lay under there. There is some talk that thieves only mess with OEM cats and don't waste their time stealing 140 dollar replacement Chinese Amazon cats. We will see. I'm only slightly optimistic.

Is the CRV's cat under hood, and right up to the cylinder head like it is on my older 2006/Civic and newer 2014 Accord, or downstream / under the vehicle?  I sort of figured both my cars were somewhat protected from cat theft based on where they are located, but now I am starting to wonder.

Her CRV, a 2005 2nd gen, the converter hangs under the car about passenger floorboard area. They cut it front, cut it rear, and snip the oxygen sensor wires. Unfortunately in my case when they cut the rear, they cut it past the flange so they ruined the mid pipe too. So that added a bit to the cost.
