The present invention 10 discloses a venturi that is installed perpendicularly to the end of the exhaust pipe 12 of a truck or like vehicle 14 thus resulting in the air flow through the venturi being at a 90 degree angle relative to the exhaust gases exiting the exhaust pipe. The present invention 10 seeks to increase the performance and efficiency of an engine of a vehicle 14 by overcoming the backpressure in the engine exhaust system created by the muffler baffles. The present invention 10 may also be installed on automobiles and other motor vehicles 14 having appropriately modified exhaust systems. A front aperture 16 for air intake tapers in width to the back pressure relief port or nozzle 20 being slightly greater than the exhaust port 18 on the bottom portion thereof and then widens to form an air discharge port 22 on the rear portion thereof that is substantially wider and longer than the air intake port 16 thereby creating an air pressure differential wherein the reduced pressure in the back pressure relief port 20 serves to create a vortex to draw exhaust gases from the exhaust pipe 12 toward the discharge port 22.
