Injen Intake and Charge Pipe Post Install Noises

[nameless.a90]

hi all, new here! apologies if this has already been asked/posted. I just installed an Injen Ram Air and Charge Pipe on my 2021 3.0 Premium. I took it out earlier for a "spirited" ride on a few pulls and everything is great. No CEL and the car ran great!

I got home and opened the hood to make sure the parts are still secure and heard a weird flapping noise near the intake? Also, when I shut the car off the engine made some weird rattling/popping noise?

Attached both videos....

NOTE: after I let the car sit a bit (about an hour) i turned it back on and the flapping noise is gone? Let it run for about 10 minutes and shut if off and the rattling noise from earlier when i shut the car off is also gone?

Any ideas? Is this something I should be worried about? Thank you all in advance!

For info on "performance" mods see below (in case any of these can also cause the noises)

Video 1 (flapping noise issue): you can hear it in the beginning of the video - may need to turn your volume up

Check the clamps around the "hump hose" are tight.
Did you remember to reuse/reinstall the OEM O Ring?

Yes, clamps are tight... o rings were reused on the new charge pipe.... what’s weird is the noise is gone.... I took it out again last night and did some spirited driving and when I got home shut the car off no noise....
