Check heat sheild no rattle, can it be that a brokeen revit can cause it to sound like a tin can or maybe something else? Lt does it 10 seconds I start the truck and when I turn the truck off?

Take a rubber mallet and tap on the catalytic converter. Sometimes they come loose inside and make noise.

Let me know.

The inside of the converter can come loose and cause a noise. I believe you already checked the heat shields. If the converter makes no noise, check the muffler too.
