lukey exhaust drone alot very anoying on long trips, were a hot dog is staight threw and gives it a bit more of a crackle when u boot it but once your up and going it dosent leave u with an anoying drone but it wont do much if you still have mufflers on, mate of mine had staight threw with hot dog sounded awsome
