The Max Flow PRXB Exhaust Brake is designed for 1994-2002 Dodge trucks equipped with HX/HY35 turbo engines. It features a unique cast housing that facilitates the fastest escape of waste gases on the market, the manufacturer states. This means more horsepower, more torque and lower exhaust gas temperatures. The brake delivers the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without using service brakes. It maintains optimum retarding performance by maximizing the exhaust backpressure throughout the entire rpm range. Unlike a typical exhaust brake, which requires high rpms to work effectively, the PRXB delivers constant exhaust pressure (braking) as early as 1200 rpm through to the maximum allowable rpm.
