I have this buzzing noise from about 3,000-4,500 RPMs. I've heard about the ATTS heat shield rattle (I think)--could this be it? I did have mt ATTS unit replaced however fairly recently. Ugh...another reason to visit my friendly Honda dealer.

Oh, sorry...it seems to come from underneath the car sort of in the middle. I am thinking it might be an exhaust shield or something transmission or ATTS related. It's sort of high pitched, and it goes away after 4,500 RPMs or so.

My heat shield rattles and I especially noticed it when my backseats were out at one point so I know exactly what it is. If mine is rattling then I am sure other peoples are rattling too. It is obviously the vibrations from the exhaust. Not sure how to cure it though. I wonder if you could take the heat shield off and coat it with something.
