Abstract: A motor vehicle having an internal combustion motor and a wheel drive mechanism, wherein the motor has an exhaust system connected thereto, includes a) an exhaust system having an exhaust pipe and a rotating accessory, with the exhaust pipe being in a fixed position relative to the internal combustion motor, and the accessory being rotatably connected to the exhaust pipe, and b) an accessory drive mechanism connected to the accessory for rotation of the accessory. The accessory drive mechanism may operate off some power source of the vehicle, operate independently of the vehicle power sources, may operate from exiting exhaust gases, ambient wind form motion of the vehicle, or a combination of the foregoing.

Abstract: A an improvement in a two wheel motor vehicle having an internal combustion motor and a wheel drive mechanism, wherein the motor has an exhaust system connected thereto, includes a) an exhaust system having a first exhaust pipe and a second exhaust pipe with the first exhaust pipe being in a fixed position relative to the internal combustion motor, and the second exhaust being rotatably connected to the first exhaust pipe, and b) an exhaust pipe drive mechanism connected to the second exhaust pipe for rotation of the second exhaust pipe. The pipe drive mechanism may operate off some power source of the vehicle, operate independently of the vehicle power sources, may operate from exiting exhaust gases, ambient wind form motion of the vehicle, or a combination of the foregoing.

Abstract: A motor vehicle having at least three wheels, an internal combustion motor and a wheel drive mechanism, wherein the motor has an exhaust system connected thereto, includes a) an exhaust system having a first exhaust pipe and a second exhaust pipe with the first exhaust pipe being in a fixed position relative to the internal combustion motor, and the second exhaust being rotatably connected to the first exhaust pipe, and b) an exhaust pipe drive mechanism connected to the second exhaust pipe for rotation of the second exhaust pipe. The pipe drive mechanism may operate off some power source of the vehicle, operate independently of the vehicle power sources, may operate from exiting exhaust gases, ambient wind form motion of the vehicle, or a combination of the foregoing.
