i know my VX has plenty of get up and go.. and the muffler adds a good deal of power, at a full takeoff on dry pavement, my TOD kicks in to 2 bars, once kicked up to 3 bars.. never did that before under acceleration except in slippery conditions.. the sound definitely isnt very high pitched.. but when it does get high and "cracks" i agree i dont like, and a resonator/time will calm that
