Drone is indeed subjective. Some people love the sound of Flowmaster mufflers and others hate them. I had friends with early 90's Mustangs and the drone of their exhaust was incredible.
On these 911 cars, the drone typically rears its head with dual outlets in the 3000-4000 rpm range and can be tuned out by the length and size of the exhaust pipes. It also has to do with the length of the collector on the exhaust manifolds. Its usually a problem on true headers and not on the original exhaust with the merge piping and singular outlet feeding the premuffler/cat delete pipe.
