Engine Brake Silencer

The Walker NoiseBraker, the industry's first low-cost, high efficiency engine brake silencer, is now available from Tenneco Automotive for a broad range of Class 8 trucks with dual exhaust systems. NoiseBraker combines industry-best acoustical performance with an ultra-high-flow design that reduces system backpressure by up to 60 percent over conventional original equipment and aftermarket silencers.
