The Walker Exhaust 22000 Quiet-Flow SS Exhaust Muffler is engineered to provide superior performance and durability for heavy-duty applications. Constructed entirely from corrosion-resistant stainless steel, this muffler offers a longer service life compared to traditional aluminized models. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of corrosion and extending the component's lifespan. Designed with precision, the muffler features internal partitions and mechanically joined tubes that accommodate thermal expansion and contraction, minimizing distortion and enhancing structural integrity. The 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 lower noise levels, while the domed heads help reduce radiated noise, delivering a premium factory-style sound quality. The muffler's direct-fit design ensures easy installation, eliminating the need for specialized fabrication or welding. This makes it a practical choice for fleet maintenance, reducing downtime and labor costs. By integrating the Walker Exhaust 22000 Quiet-Flow SS Exhaust Muffler into your fleet's maintenance program, you can expect improved operational efficiency and reduced maintenance expenses over time.
