The heat shield ends after the catalytic converters rusted and caused a rattle under acceleration. I guess it’s a heat shield to protect the drive shaft from heat. I used some stainless steel hose clamps to secure the heat shields for now.

Anyone know if this is a good fix or if it’s covered by warranty? Also anyone else with this issue? Not sure if the stainless steel will some some kinda weird reaction with the exhaust pipe material.
