High pitch, metallic ringing noise under acceleration.

[702to540]

I'm trying to locate a rattle as well. Limited time to figure it out though. Seems to only do it on cold start, during high idle. Sounds like a loose heat shield or spring or something. It's loud enough though to be annoying. Sounds like it's going to rattle apart. lol I tried to upload a video, but the file is too large. I'll try and get a shorter one.

If you look under passenger side back door there is 2 springs on the exhaust they control the butterfly valves inside of exhaust. When i tap on my on exhaust pipe the valve rattles i have not figured out how to keep the one valve from rattling

I’ll check it out. Conveniently, it didn’t do it today for the first time while I was watching. Lol

Looking for some help here from the forum warriors… I’m getting a High pitch, metallic ringing noise under normal acceleration. If you guys could turn the music off and just listen to see if you all hear this almost metallic ring noise under part acceleration that gets louder and quieter depending on throttle input. Not sure how normal this is. Thanks to you all.

I have a similar noise. Mine is the wastegate actuator rattling. No fix at this time by the dealer
