The Walker 50075 Quiet-Flow SS Exhaust Muffler Assembly is engineered to provide superior performance and durability for commercial vehicle exhaust systems. Constructed with 100% corrosion-resistant stainless steel, this muffler offers a longer service life compared to traditional aluminized mufflers. Its direct-fit design ensures easy installation without the need for specialized fabrication or welding, minimizing downtime and labor costs. The muffler features internal partitions and mechanically joined tubes that allow for expansion and contraction during temperature changes, reducing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds further contribute to its stability and longevity. For optimal acoustic performance, the muffler utilizes OE-style louvered tubes and domed heads, effectively lowering noise levels and providing a premium factory-style sound. This design also helps reduce radiated noise, ensuring compliance with noise regulations and enhancing driver comfort. The internal drainage system effectively reduces moisture collection, preventing condensate acids from accumulating and extending the muffler's lifespan. Acoustic and flow testing validate the muffler's design, ensuring it meets OE-style sound quality and performance standards. The Walker 50075 Quiet-Flow SS Exhaust Muffler Assembly is backed by a limited lifetime warranty and a 90-day Safe and Sound® Guarantee, offering peace of mind and reliable performance for fleet operations.
