Has anyone ever noticed a jingling noise coming from there car at higher RPM's?

Does it sound like marbles in a can? Or a slight pinging sound? It's normal, it is just the ports in the engine opening/closing.

ya that is a pretty good way to desribe the noise actually... It only happens at high RPMs, like 7k+.. and I can sometimes hear it when I drive under a bridge or something, just not nearly as loud..
