Helmholtz resonators help a ton. Just bottle resonators with caps on them. Technically they need to be sized to cancel out rasp/drone. They do a great job adding a deeper tone.

So based on my current system, do you think it would help to add an additional hemboltz chamber somewhere else in the system? I'll have the Motordyne ART fabbed to restore the original chamber size.
