PacBrake has designed a Max Flow PRXB exhaust brake specifically for 1994-2002 Dodge trucks equipped with HX/HY35 turbo engines.
The brake features a cast housing that facilitates faster escape of waste gasses, offering more horsepower, torque and lower exhaust gas temperatures.

The new Max Flow delivers strong braking horsepower, greater speed reductions and shortest stopping distances possible without the use of service brakes, according to the company. It maintains retarding performance by maximizing the exhaust backpressure throughout the entire prm range. The PRXB delivers constant exhaust pressure (braking) as early as 1,200 rpn through to the maximum allowable rpm.

It mounts directly to the turbocharger outlet with a five-bolt flange in the Directmount design, eliminating the restrictive factory flange. This enables the turbocharger to spool up faster, decreasing turbo lag and, in turn, increasing horsepower and torque while lowering exhaust gas temperatures.

The Max Flow PRXB exhaust kit comes with the 4-inch Max Flow designed PRXB exhaust brake, air compressor, air tank, curly hose and accessories. Exhaust pipe adapters are available to fit factory and all larger aftermarket exhaust systems. It is available through Pacbrake's network of dealers in the U.S. and Canada.
