Do catalytic converter shield work?

A bolt on or welded shield professionally installed? My guess it would deter and or slow the thieves down, but not eliminate the possibility of it being cut out and stolen. If thieves want something bad enough they will find a way to take it.

Too bad there's not some kind of agency that apprehends thieves and finds some kind of punishment for their acts .

As stated above if they want they will get it no matter what steps you take.

Anything that gives you peace of mind is worth it in my opinion. For example, I have always had locking gas caps on all of my vehicles. I know there are other ways for a crook to steal my gas but the locking cap is a deterrent and it gives me peace of mind. Hope that helps! Jim

OK... Nobody here has ever stolen a car... Thieves want to get in and out quickly. If the low- lives see something that's going to take extra time, they WILL move on to another car..... It might be a great idea to just put a sign on the rocker panels "This car has a catalytic converter shield." That might be enough.

I like the idea of a sticker
