Going to the drivers side of the engine can hear a rattle as well, not so much on passenger side. This is why I never noticed it inside the car while driving it, with all of the moving parts the faint sound can be muffled by the sound of the engine, supercharger whine and the exhaust note. So, I called my dealership to inform them my car needs service based on the noise described in the letter I received from GM. I have an appointment scheduled this week. Thanks!

Glad your getting it taken care of.
Mine was the same way, you could not hear it from idling or even when the Hood was popped and you standing by it. Me being as anal as I am had to put my ear to the cover and sure enough very faintly I could hear it. It did get to the point before I brought it in that you could start to hear it by just being in front of the car with the Hood open.
Glad I caught it early, that's why people should really get a close listen.
The people that say they can hear it very faintly and that they'll keep an eye on it are not thinking it through in my opinion.
It has to be doing more damage then good. Get it fixed!! The install of the new one went very smoothly and everything is sounding as it should.
The only thing is last week my malfunction indicator lamp came on and it ran a code for bank 1 sensor 1 O2, only mod I have is a rotofab and a mild to wild switch....... the car drove perfectly still, so I brought it down to the dealership and they are convinced it had to do with the new supercharger install. Not sure I'm buying that but they cleared it and it hasn't been back yet, so will see, I'll keep an eye on it .... hopefully it never comes back.
Personally I think it has to do with the M2W switch....
