Tin can rattle upon cold start and driving m: UPDATE not wastegate

[SCAR911]

So It’s definitely not the wastegate. I did the recommended spring fix. Below is the video I took of the sound. It’s definitely in that area that’s creating the tin can sound. Any ideas?

Truck running ok? Almost sounds like lose turbo couplers. That's pretty substantial

How many miles on your truck? Sounds like catalytic converters. On a cold truck, hit them with a rubber mallet. I bet they are broken and will rattle.

Ive had this happen but my truck would intermittently stall due to restriction.

What happens when you rev? Kinda sounds like something hitting the flywheel. Maybe the starter isn't disengaging completely?

Sounds like a 10mm hitting the flywheel.
