Abstract: Unobstructed, pressurized air from the forward movement of a vehicle such as a pickup, SUV or automobile is forced into an air scoop (mounted to the undercarriage of the vehicle). This air is then channeled through a section of exhaust pipe (having the fewest possible bends) parallel (with an approximate 4? separation) along the muffler to the end of the tailpipe. A section of exhaust pipe (“crossover pipe”) is welded to the tailpipe outward at an acute angle which is then welded at an obtuse angle to the pressurized air pipe with both pipes being welded open to each other. As the pressurized air passes the crossover pipe, a vacuum is created in the crossover pipe pulling gases out of the tailpipe and then pushing them out of the pressurized air pipe, with this process reducing backpressure in the exhaust system and improving fuel economy.
