Me too. One thing I didn't mention is that I heard the noise a year ago and then it went away. I live in Texas and the only thing I can think of that has changed recently is the weather.......the daytime temps are now around 75 instead of the usual 95. Not sure if that has anything to do with anything, but I first heard the noise around the same time last year. At first I thought it was the headers cooling as it does not match the rev of the engine at all like others have stated.

It would be good to see what they say, even if it is "normal" it would be good to know what is causing the sound.
