You could perhaps do some calculations and tune it to cancel out any drone frequency that's bugging you. Just need to figure the volume of the dead end cylinder you're making and weld a cap on it.
My 2 cents...

Thanks, the Helmholtz resonator effect did cross my mind. But I have no idea on how to approach calculating the frequency the resonator would cancel out. So unless someone with a little more engineering knowledge can chime in, I'd be guessing as to the size lol. If I don't get that figured out I'd just cut it as short as possible to save weight.
