How to protect my Catalytic convertor?

That hurts just looking at it

 

Actually not a bad idea!
Wish someone would make something like a high-temp kevlar mesh wrap like they put in chain saw chaps, one cut and the mesh wraps around the chain sprockets and binds the saw.

…but that razor wire wrap would stop even the first cut!

 

That's actually a really interesting idea. Going to look into fabbing something. While less exciting and interesting than my rats nest of razor wire, it would be far less janky lol

 

Good thought but does that thing rattle and jingle down the road> $.02

 

Nope, at least I can't hear it.

 

Something like this @1:20

You could also take strands of razor wire and attach the ends onto a ring of wire around both ends of the cat and twisted it so the strands spiral and form a twisted net around the cat and tack the rings onto the pipe with a welder, that would make the strands pop out when the first cut is made.

 

Or…….

 

just tether a 10' alligator under the truck. Be sure to post a sign. "Warning: Live Anti-Theft Device"

Tip, keep the feeding of the device no more than 1X/month and water regularly
