The Walker Exhaust 22502 Quiet-Flow SS Exhaust Muffler is engineered to provide superior performance and durability for commercial vehicle fleets. Constructed entirely from corrosion-resistant stainless steel, this muffler offers a longer service life compared to traditional aluminized mufflers. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and extending the component's lifespan. 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. This design ensures a precise fit and minimizes installation time, reducing labor costs. The muffler's internal partitions and mechanically joined tubes allow for expansion and contraction during temperature fluctuations, minimizing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds provide additional stability, contributing to the component's overall durability. For optimal acoustic performance, the muffler utilizes OE-style louvered tubes to lower noise levels and OE-style domed heads to reduce radiated noise, delivering a premium factory-style sound quality. This design ensures compliance with noise regulations and enhances the driving experience. Acoustic and flow testing validate the muffler's design, ensuring it meets OE-style sound quality standards. Backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound® Guarantee, the 22502 Quiet-Flow SS Exhaust Muffler offers fleet operators a reliable and cost-effective solution for maintaining optimal vehicle performance and compliance with noise regulations.
