The Walker Exhaust 50087 Quiet-Flow SS Exhaust Muffler Assembly is engineered to provide superior performance and durability for commercial vehicle applications. Constructed with 100% stainless steel, this muffler offers enhanced corrosion resistance, extending its service life compared to traditional aluminized mufflers. The internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and ensuring consistent performance over time. 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 minimizes downtime and labor costs, contributing to operational efficiency. Internally, the muffler incorporates partitions and mechanically joined tubes that accommodate expansion and contraction due to temperature fluctuations, reducing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds further reinforce the assembly, providing stability and a longer service life. For acoustic control, the muffler utilizes OE-style louvered tubes to effectively lower noise levels, while domed heads help reduce radiated noise, delivering a premium factory-style sound quality. This design ensures compliance with noise regulations and enhances the driving experience. The Walker Exhaust 50087 muffler is validated through rigorous acoustic and flow testing, ensuring it meets quality OE-style sound standards.
