Recommendations for installing a Rebar Cage around Catalytic Converter?

My catalytic converter was stolen a few weeks ago. I had it fixed and would like to get something to protect it. The shop I was at put like a chain around it but its making the car rumble when I press the gas and I really don't like it or know how much of a deterrent it will even be.

I want something more protective that won't make noise or rattling/rumbling. Perhaps something like a Rebar Cage.

Has anyone had something like this installed at a shop in Chicago , specifically a custom rebar cage, and have a recommendation?
