With a few recent posts regards stainless steel, I had the urge to replace some corroded nuts n bolts on the cat heat shields.
Once I managed to separate the parts you begin to appreciate how or what may cause a rattle.
There are parts that are not easily (if at all) visible when assembled. (the half semi circle brackets/spacers)
The pics that follow show all the component parts and then a semi re-assemble flow.
The last pic, is a pic of a little secret sauce. The original piece was completely beyond salvage. I suspect the heat shields where never designed to be removed. So a very nice man in a shed made a spacer for me. Thank you.
As the shields where never designed to come off. There is no torque setting for them. I have gone for an arbitrary 15nm.

Nice work! Mine are held together with jubilee clips, which is fine as you can't see them. But after this I both know they are there and know the satisfaction of a real solution. Winter maintenance list started in the same month my car wakes up.....
