They are designed to be used as part of a Kooks systemWith a full 1 3/4" Kooks system WITH cats the drone is pretty decent, at least IMHO but then again I dont have a cam ect hehe
With how simple the axle backs are you should just get a flange on the other end and mount up mufflers till you find a set you like. Corsa has some mufflers I think may have the right chamber size for the G8 and you not having DoD will make it that much easier to find a tone you like![]()
