Help Identifying Part

This fell off my truck a few days ago. Any help on where it goes would be appreciated.

 

It's a heat shield for a catalytic converter. Seriously, you should be able to look under there and tell where it goes.

 

That would be a heat shield for a catalytic converter. Part of the exhaust.

Thanks for the help.

Go to store get new bolts and nylock nuts so they don’t back out
That’s how i fixed mine

 

Do those tend to vibrate/resonate at a certain rpm? My 5 speed manual truck only around 1800-2000 rpm, and only if I step on the accelerator. If I go easy on the pedal it doesn't happen, so maybe something else.

 

Yes the heat shields can resonate if they are getting loose.

 

It could definitely be the heat shields. My Taco was making a odd vibrating noise at low RPM until mine fell off.

 

It's kind of strange that it's only if I give it gas, so it's not necessarily always heard between 1800-2000 rpm. I had a Subaru with heat shields that rattled - very common for them to do that. This sounds different, more of a harsh drivetrain sound. It's hard to pinpoint where it's coming from.

Not ruling out the heat shields though. I wonder what diameter pipe clamp was used in the photo.

Returned to edit this - looked closely and I see it's 2 clamps,
