I have been analyzing the sound and thought I'd be a little more specific. It comes in at about 2100-2400 RPM in all gears(I've at least heard it in the first 4) and it's much louder when the engine is cold. It kind of sounds like a moped engine lives in my car and gives a little rev during those 300 rpms.
