Its the manual, not a fan of autos, feel less in touch with the vehicle. Nah, no drone at all kjc. The resonator is designed to take care of any drone and does a great job, especially on the highway. Even without the resonator I believe there would be little if any drone because the turbo silences most of the sound in the exhaust. Not sure if your aware of what causes drone, but from my understanding its from having too big exhaust for the application at hand... just from a forum on here somewhere. The standard setup is pretty much perfect for the stock car, minus the sound, or lack of.
