If you're describing a metallic buzz around 2k -3k you may want to check if the expansion joints on the header are contacting the alloy skid plate. I had this with my PSR headers. If its happening, you can see the marks looking down through the engine (ie no need to remove skid plate)
Easily fixed with a hammer and punch.
I posted about it somewhere here if you need photos.
