Cutting brake noise but not performance

Heavy-duty fleets looking to improve performance can now turn to the Walker Mega-Flow NoiseBraker muffler. Manufactured by Tenneco Inc, the NoiseBraker is a direct retrofit for Class 7 and 8 vehicles, capable of reducing backpressure and quieting the engine brake to legal limits.

Featuring a straight-through, ultra-high flow design to reduce engine backpressure by as much as 60 percent, the NoiseBraker improves engine efficiency compared with traditional heavy-duty muffler designs.

Available for single- and dual-exhaust applications, the NoiseBraker is 2 to 4 decibels (dB) quieter under engine brake-induced deceleration. The muffler uses fiberglass roving technology and dual concentric Helmhotz tuners to quiet engine brake noise without affecting brake performance.

Each NoiseBraker is covered by a limited lifetime warranty and Tenneco's 90-day “Safe & Sound Guarantee” money-back trial offer. Access www.walkerheavyduty.com for more information.
