Heavy-duty fleets looking to improve performance can now turn to the durable Walker Mega-Flow NoiseBraker muffler, maker said. According to Tenneco Inc., the manufacturer and marketer of the NoiseBraker, the muffler is a low-cost, 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 as compared to traditional heavy-duty muffler designs. Other engine brake silencers channel exhaust flow through a series of baffles and restrictor tubes, thereby increasing backpressure and reducing engine efficiency.
Available for single- and dual-exhaust applications, the Walker NoiseBraker is 2 to 4 decibels (dB) quieter than the industry’s best OE mufflers 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.
Engineered for durability and longer life, the NoiseBraker features re-metallized welds for greater corrosion resistance.
Each Walker Mega-Flow NoiseBraker muffler is covered by a limited lifetime warranty and Tenneco’s exclusive 90-day “Safe & Sound Guarantee” money-back trial offer.
Walker Commercial Vehicle also manufactures and markets the innovative Mega-Flow muffler, Y connectors, stack pipes, spark arrestors, tubing and adaptors, tail spouts, clamps, hangers and other hardware. The Walker brand also includes a complete RV emissions control product line.
