Looking on youtube....
Lots of problems with heat shield rattles.  The easy solution is to remove the shield or wrap with a hose clamp.  Once the snow melts up here in Pennsylvania, I'll fix the shield.  I have a mig welder....  Anyone weld the orig bracket to the exhaust pipe???  I'm kinda thinking I might have to braze due to the fact the exhaust system is stainless steel??
Keep the suggestions coming...  Still trying to find the best fix.
