I have Eisenmann Sport with Encore x-pipe /w HFC and I don't even know what drone is or what this drone you guys are talking about. The car sounds quiet and mean and powerful from the inside but it's menace from the outside. It gets loud above 5k rpm, sounds like an exotic car but not loud and cheap like the old hondas with loud exhausts you see around. I wet myself almost every morning when I start up the car with one of my windows down
