My theory is that the softop while down insulates my ears from the drone, and the ambient noise helps to drown it out.

What makes you think a helmholtz chamber would reduce performance?

Stop whinning and sell the system.

Dynomat will just weigh you down.

Use Dynamat Extreme -- it's much lighter than the older Dynamat .... At least it stops the droning of the trunk panels that were caused by my trunk mounted subwoofer. Seems like it would be worth a try for dampening the resonance emanating from the muffler. But hey, get yourself a proper muffler!
