Default Strange engine note...

So after I installed my airraid cai I've been noticing a strange intake sound. It almost sounds like a MDS drone coming from the intake side of the engine. I think I've noticed it with the tranny in manual mode to shut off MDS. If I add a slight amount of gas or let off the gas the noise stops immediately. Any thoughts?

Different CAI's will will be louder at certain RPM's than others and some have no drone sound at all that is audible. Our ram's also have active intake runners which will change in sound depending on rpm and load on the engine

That's interesting, I have the same airraid cai in the charger 5.7 but don't get that drone. Does the 2013 charger have the same active manifold as the trucks?

Only the trucks have them that im aware of. The truck uses the long runners for torque and switches to short in the upper rpm.
