Weird noise coming from my exhaust. Berk HFC and Magnaflow

After installing my HFC's and exhaust I noticed this weird noise. Well i took everything off and re-installed it. It seems to be coming from the X-pipe. And only at 2,000 RPM's. Anyone know what it could be

I'll add another vid later tonight.

<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/cGT-cEApbgY&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/cGT-cEApbgY&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

New video (you can see the pipe shake and i think thats what the noise is):

Don't have access to youtube at the office... Can you explain the noise? Rattle? Clunk? Buzz?

maybe an exhaust leak but its hard to tell from the vid. It doesnt sound like a rattle so its probably not the pipes hitting the heat shield.

I've never heard an exhaust squeal like that before. I triple checked all the connections and everything is snug. Maybe it's just the way the exhaust is traveling through the x-pipe.

I also sent an email to hottexhaust to see what they think. We'll see.

I also have the same sound after I installed FI HFC.
I never had this noise when I had intake & exhast so
I'm sure it's coming from HFC. It kinda sound like
air being sucked in.
I also wonder why...

Dipstix,
I think taking the HFC off will be easier step.
