Oh so this doesn't just cut out the drone frequency but quiets down the overall sound of the exhaust?

Besides switching exhausts this is your best bet.

Aren't cutouts used to make a stock exhaust louder, rather than to make a loud, droning exhaust quieter?

Cut-outs have nothing to do with drone, they're just actuated butterfly valves that allow *any* exhaust to operate in two modes.
