Abstract: Pickup truck exhaust back pressure reduction system is composed of a base plate that is an exhaust inlet which is mounted to the pickup truck bed floor just behind the cab, a rotating barrel tower which is stationary and vertically mounted on top of the base plate as a trap for the exhaust stream, a rotating barrel and bearings assembly which rotate in the inside top of the rotating barrel tower, a flywheel being attached to the upper bearing shaft and the motor being attached to the trim plate which surrounds the rotating barrel tower adjacent the flywheel and within engaging distance of the flywheel. The rotating barrel is actuated by a variable D/C voltage current which is powered by the pickup trucks engine and rotates slow at low engine r.p.m.'s and higher at high engine r.p.m.'s which then at high r.p.m.'s the turbine which is located in the lower hollow end of the rotating barrel starts to create vacuum which pulls the exhaust stream and creates back pressure reduction.
