The Walker Exhaust 70008 Quiet-Flow SS Exhaust Muffler Assembly is engineered to provide superior performance and durability for commercial vehicle applications. Constructed with 100% corrosion-resistant stainless steel, this muffler offers a lifespan significantly longer than traditional aluminized alternatives. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of corrosion and extending the component's service life. Designed for direct-fit installation, the muffler features OE-style hangers, brackets, and pipe routings, facilitating a straightforward, bolt-on replacement without the need for specialized fabrication or welding. This design ensures minimal downtime during maintenance, enhancing operational efficiency. The muffler's internal partitions and mechanically joined tubes accommodate thermal expansion and contraction, minimizing distortion and maintaining structural integrity under varying temperature conditions. Spun-locked heads and OE-style spot welds further contribute to its stability and longevity. Acoustic performance is optimized through OE-style louvered tubes that effectively lower noise levels, while domed heads reduce radiated noise, delivering a premium factory-style sound quality. This design not only meets but exceeds OE standards, ensuring consistent and reliable performance. The Walker Exhaust 70008 muffler is validated through rigorous acoustic and flow testing, confirming its ability to deliver quality OE-style sound. Backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound Guarantee, this muffler assembly offers peace of mind and confidence in its enduring performance.
