I don't know what year of RT you have, but I know some of the earlier ones had this and you could go to the dealer and have it fixed under warranty (some sort of documented RRT repair). Mine had this, and I had the service done. I have no idea what was replaced or changed. I just know the noise went away, and I cannot recall it ever emerging again.

It's not that I really needed 370 hp...but having 150+ hp riding shotgun at a moment's bidding w/o a 6000 rpm moonshot is what makes me feel like I'm in the right car for me. The roar of a v8 seals the deal!
