I don't know what drone sounds like. what's an annoying buzz to you?
I've got drone on mine. I removed the muff and resonator and welded stock diameter 1.75" pipe in their place (for now). The exhaust sounds awesome! Throaty and mean for such a small displacement, but the drone can be annoying.
The best I can describe the drone is that at steady engine speeds on the freeway, around 2000 RPM, the exhaust note hits a frequency that is less than enjoyable, i.e. annoying. It doesn't sound "bad", actually it sounds like a B52 bomber carrying it's payload over the sea

, but after 5 minutes of it, it starts to wear on your comfort level and fatigue your ability to ignore it.
I don't mind it so much. The stereo easily drowns it out. But if you're driving a long trip with friends that you want to converse with, it's............ Annoying.
