engine 'rumble' around 1200 RPM - 10/18/07 09:15 AM

I have an '04 Grand Prix GTP Comp G and I've noticed recently pulling away from a stop sign or red light as I'm accelerating I hear this metal hollow 'rumble'. I've heard it on other Pontiacs and have always wondered - is this something that should be looked at?

Thanks!
