Product Details: The Walker Exhaust 21396 is a high-quality exhaust muffler designed to enhance vehicle performance and durability. Constructed entirely from corrosion-resistant stainless steel, this muffler offers superior longevity compared to traditional aluminized options. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of corrosion and extending the component's service life. The muffler's design includes internal partitions and mechanically joined tubes, allowing for thermal expansion and contraction, thereby minimizing distortion and maintaining structural integrity over time. Spun-locked heads and OE-style spot welds further contribute to its stability and durability. For optimal acoustic performance, the 21396 features 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. This muffler is engineered to fit specific vehicle models, ensuring a direct-fit bolt-on replacement without the need for specialized fabrication or welding. Its dimensions—29.5 inches in overall length, 11 inches in width, and 5.5 inches in height—make it suitable for various applications, particularly for the 2000-2003 Dodge Durango. By choosing the Walker Exhaust 21396, fleet operators can expect enhanced vehicle performance, reduced maintenance costs due to its durable construction, and improved acoustic comfort, all contributing to the overall efficiency and reliability of their operations.
