Abstract

Abstract An exhaust pipe extension having movable fan blades mounted on a center axle which blades and part of the axle extend into an opened vehicle exhaust pipe. The other end of the same axle is fixed connected to a rotatable end decorative visual spinner within a hollow housing. To provide for individuality the visual spinner can take on a variety of different sizes and shapes. The spinner rotates in unison with the propelled fan blades which blades are driven by the vehicle's exhaust gases. Appropriate easily detachable mounts are used to fix the housing and its axle and the fan blade members to the vehicle's exhaust pipe to provide for an attractive add-on accessory.
