Sounds like a heat shield noise...if it only happens at a certain rpm, that is where the resonance occurs that makes the shield rattle. A ping is very noticeable, almost sounds like a small hammer banging against a large piece of metal. If it is a rather thin metallic noise, it is almost certainly just a rattle of a metal heat shield.
