The Walker Exhaust 47772 Quiet-Flow SS Muffler Assembly is engineered to provide superior durability and performance for a wide range of vehicles. Constructed entirely from 100% corrosion-resistant stainless steel, this muffler offers a lifespan significantly longer than traditional aluminized mufflers. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and extending the component's service life. Designed for easy installation, the muffler features a direct-fit, bolt-on replacement solution with OE-style hangers, brackets, and pipe routings, eliminating the need for specialized fabrication or welding. The internal design includes partitions and mechanically joined tubes that allow for expansion and contraction during temperature fluctuations, minimizing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds further contribute to the muffler's stability and longevity. Acoustic performance is optimized through OE-style louvered tubes that lower noise levels, while domed heads help reduce radiated noise, delivering a premium factory-style sound quality. The muffler has been acoustic and flow tested to ensure it meets OE standards, providing reliable and consistent performance. Backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound® Guarantee, the 47772 Quiet-Flow SS Muffler Assembly is a dependable choice for fleet operations seeking to enhance vehicle performance and reduce maintenance costs.
