Pacbrake PRXB Exhaust Brake Performance for Diesel Trucks

PacBrake offers a comprehensive line of exhaust brakes for the light and medium duty diesel aftermarket. They are grouped into three different categories, Fixed Orifice, PRXB (Pressure Regulated Exhaust Brake) and the Loadleash. The Loadleash works in conjunction with the factory installed VGT exhaust brake, primarily for the 2007 and newer 6.7L RAM Cummins trucks and commercial trucks that have a VGT turbo controlled by the ECU. The main difference between the fixed orifice exhaust brake and the PRXB is the PRXB has wastegate design that regulates exhaust backpressure as engine speed changes. The valve maintains near constant engine backpressure throughout the entire RPM range, providing maximum exhaust braking power at all times.
