Default Flywheel chatter or what ?

So when I press my clutch in I don’t hear nothing but when I let it off I hear some noise coming from the trans in my 03 that sounds like spinning.
I bought the car 4 months ago and the kid I bought it from swapped the clutch in it before I bought it, he bought a clutch kit from Z1motorsports and it came with a throw out bearing, which I thought it was that but it has done the noise ever since I’ve had the car and I didn’t know if it was flywheel chatter or what, I do not know what kind of flywheel is in it I do not know if he replaced that too or just the clutch
I also have a video of the noise

Original trans? Miles on it? (or if replacement, miles on "new" trans?)

Could be the ubiquitous input shaft rattle on the trans. More prevalent on newer transmissions, e.g., CD009, CD00A, JK41, etc. But as Trav said (based on vid), could be normal.

It’s a cd001 I’m pretty sure that’s what came on the 03 and it’s has 150k miles on it

Mine does the exact same thing, I thought it was an issue but seems to be a common thing. Not sure if it's a common problem but rest assure I have the same exact thing going on haha

They're pretty noisy. I hate listening to the racket when I pull next to the carport. But it and the clicking clutch pedal/master are apparently normal.
