The Walker Exhaust 21338 Quiet-Flow SS Exhaust Muffler is engineered to provide superior performance and durability for your vehicle's exhaust system. Constructed entirely from corrosion-resistant stainless steel, this muffler offers a longer service life compared to traditional aluminized options. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and extending the muffler's lifespan. Designed for a precise fit, the muffler features OE-style hangers, brackets, and pipe routings, facilitating a straightforward, bolt-on installation without the need for specialized fabrication or welding. The internal partitions and mechanically joined tubes accommodate expansion and contraction during temperature fluctuations, minimizing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds further contribute to the muffler's stability and longevity. For optimal acoustic performance, the muffler incorporates OE-style louvered tubes that 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 muffler's design, ensuring reliable and consistent performance. The Walker Exhaust 21338 Quiet-Flow SS Exhaust Muffler is compatible with specific vehicle models, including the 1998-1999 Dodge Durango, and is backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound® Guarantee, providing confidence in its quality and durability.
