The Walker Exhaust 22075 Exhaust Muffler is engineered to provide superior performance and durability for commercial and heavy-duty vehicles. Constructed with 100% 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 corrosion 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 seamless integration into existing exhaust systems. 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 incorporates OE-style louvered tubes that effectively lower noise levels, while OE-style domed heads help reduce radiated noise, delivering a premium factory-style sound quality. Acoustic and flow testing validate the design, ensuring consistent and reliable performance. The Walker Exhaust 22075 Exhaust Muffler is backed by Walker's limited lifetime warranty and the exclusive 90-Day Safe and Sound® Guarantee, offering peace of mind and confidence in its quality and longevity.
