Test pipes increase propensity for drone. Really any change to reduce restriction in the x pipe will do so.
If an aftermarket exhaust pitches itself as being drone-free, understand that that claim is when fitted to a factory x pipe. Once you alter the upstream, those promises are void. This is how it was explained to me by the engineer at Borla when I was in your shoes shopping options.
Drone is subjective. I can hear a tone from my Corsa at freeway speeds. Some would call it drone but to me drone is both continuous and disresonant, meaning unpleasant to the ear. The corsa is not disresonant.
