ABSTRACT:
The present invention10discloses a venturi that is installed perpendicularly to the end of the exhaust pipe12of a truck or like vehicle14thus 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 invention10seeks to increase the performance and efficiency of an engine of a vehicle14by overcoming the backpressure in the engine exhaust system created by the muffler baffles. The present invention10may also be installed on automobiles and other motor vehicles14having appropriately modified exhaust systems. A front aperture16for air intake tapers in width to the back pressure relief port or nozzle20being slightly greater than the exhaust port18on the bottom portion thereof and then widens to form an air discharge port22on the rear portion thereof that is substantially wider and longer than the air intake port16thereby creating an air pressure differential wherein the reduced pressure in the back pressure relief port20serves to create a vortex to draw exhaust gases from the exhaust pipe12toward the discharge port22.
