A muffler and exhaust extractor especially adapted for internal combustion engine powered vehicles such as over the road diesel tractors. The muffler and exhaust extractor generally stated comprises a pair of spaced curved airfoils for directing the airstream produced by the moving vehicle through an open ended converging-diverging passage to form a low pressure area for gas extraction, and means for mounting the airfoils such that the low pressure area is adjacent to and in communication with the exhaust outlet of the vehicle.

An exhaust pipe attachment for internal combustion powered vehicles comprising: first and second curved airfoils mounted parallel to and spaced from one another and to a longitudinal axis generally perpendicular to the direction of movement of the vehicle to form an open ended converging diverging passageway for accelerating airflow therethrough to produce a low pressure area; means for mounting the first and second airfoils in the airstream produced by moving the vehicle generally perpendicular to the direction of flow of the airstream with the open ended converging diverging passageway adjacent to and in communication with an exhaust outlet of the vehicle such that the exhaust gases flow into the low pressure area and such that turbulent air is produced on either side of the airfoils for dissipating the sound waves formed by the exhausting gases.
