Default What is this noise!? Help

Ok so I have this chatter coming from what I think is somewhere in the drive train. Sometimes it's there and sometimes it's not. I have a JWT clutch/flywheel but this is not the usual chatter I hear. Even with the clutch depressed it still makes the noise. Video posted below.

I have the same combo and mines doesnt sound that bad. But, I do have the chatter sound. I also get a chatter/knock between 2-3k rpm on slight load or when My shift brings my rpms below 3k. Not sure what it is.

You absolutely can't hear it from the engine bay (hope not)? If it's 100% from the trans, who installed the clutch/flywheel? I've never heard a loose flywheel in person, but I'm not sure how quickly it would fail. It definitely sounds like a rapid, rhythmic rattle, so I wouldn't think it's something external to the transmission. The best you can do right now is jack up the car with it on and hit things with a rubber mallet as well as listen more closely to the sound.

The flywheel has been on for a good amount of time now, any chance it can be slowly loosening?
