Noise from drivetrain, felt through floorboard

[awsom-0]

Hey guys, I started the car up the other day and noticed at idle and low rpms there was a weird noise. I haven't changed anything on the transmission aside from a clutch/flywheel job. I'm thinking it might be the carrier bearing but would like other inputs to what it might be. Here's the video link http://vimeo.com/41813728

Does it do it stopped? If so that would eliminate anything ds back.

Does the noise go with rpms?

I haven't driven it since but yeah it's when im stationary. It goes away when I rev it past 1100-1500 rpm.

What kind of clutch?

Does it go away when you push the clutch in?

I have an ACT sprung 6 puck and Fidanza flywheel. No, it doesn't, I just started it up and noticed when i revved to about 1500rpm is when it is more prominent.

Best bet would be to get under car with a screwdriver to your ear or a stethoscope and listen while it's running.

I finally got around to taking it out for a drive and looks like it does that noise while driving too.

UPDATE: I finally got it up in the air and the driveshaft seemed to be okay, but I had a friend wiggle the exhaust and I think that's the culprit. It made the exact noise and everything. I'm going to have a muffler shop weld up an extra hanger so keep it from moving.
