An exhaust tip assembly including a cylindrical collar adapted to be secured to the distal end of a vehicular exhaust pipe and to extend beyond the distal end of the exhaust pipe. A rigid support structure is secured inside the collar and a turbine is rotatably coupled on the distal side of the rigid support structure. In a preferred embodiment, the turbine is concentric with the collar and has a fixed axial position adjacent the distal end of the cylindrical collar. It is also preferred for the turbine to form a plurality of vanes facing the distal end of the exhaust pipe such that exhaust gases pass over the vanes and cause the turbine to freely spin in one direction. It is further preferred if the turbine is free to continue spinning independent of exhaust gases continuing to exit the exhaust pipe through the collar.
