You can add some Dynomat behind the belt cover. You know the shield that is behind the seats that gives you access to the serpantine belts.
If you add some Dynomat there on top it should make the noise level lower.

Yes. What you have is called drone. How much did you pay for this custom job? Fabspeed has a high performance system that they guarantee is 50 state emissions legal and does not have drone. And I hear it sounds great. I plan on buying it soon.
