A rebar cage would be just as effective. But you're right, it's sad we have to do this to protect something that we shouldn't have to worry about.
if you could almost add a additional barrier around the rebar made mostly of grit or something that would eat blades and make heat like a Mfer, but I cant think of how to do that and not be able to chisel off

Rebar alone will eat blades. I tried cutting rebar with metal jig saw blades, and also metal sawzall blades, and each blade lasted maybe 3 to 5 seconds before the teeth were gone. I had to break out the grinder and use the cutting wheel to make my cuts.

Oh I’ve only ever seen rebar cut with a concrete saw so I didn’t even think about that. What makes rebar do that, density or maybe that grid pattern on it for surface area contact I think

Hardened steel, much harder than any metal cutting blade. When I was a mason's tender, we'd cut rebar with a rebar cutter. It's like a big bolt cutter mounted on a platform that sits on the ground. #4s weren't too bad, #5 and bigger was a royal pain cutting rebar with that thing.

Typical Mild steel is 36ksi tensile yield strength.
Standard rebar is 60ksi yield and up to 80ksi depending on the grade of steel.

It explains a lot, when I Made a tool to adjust garage door I did notice it took a lot of a blade and a lot of time on my chop saw.... and when i put it to the grinder to make the tips the right size/shape, it took a lot of grinder time, quenching to be able to hold it, and a lot of the wheel was used lol. I even have the green epoxy rebar

Here in AZ used cats aren't worth ****. Recyclers won't pay you much for them, the emissions repair shop I used to work for sells them for $20 each to a recycler... You can buy a new cat off of Rockauto for $60. The only ones that are expensive are the ones that are unusual, Ford F-150's etc that are a pain in the ass and weird shaped. Even then they still have no resale value.
My neighbor's 1996 Toyota Land Cruiser had 2 installed on his vehicle and they were stolen. 1 cost him 1800 and the other was 2700. Lucky for him, insurance paid all but 100.

I had a '91 Honda Accord SE back in the day and my cat got all clogged up, My friend told me to take it off and get a steel rod used to chip Ice off a sidewalk and just pound it through the cat and re install it. It passed inspection and emissions. So if you have one stolen, just find an imitation and weld it back on.

i WOULD say emissions states, but they do say modifications to your emissions and exhaust are illegal... so id say it would be better to weld in a cat for inspection and remove once inspected. illegal yes, but if both are illegal may as well do the cheaper and easier and less likely to be robbed way
