The Walker Exhaust 21746 Quiet-Flow SS Exhaust Muffler is engineered to provide a direct-fit replacement solution for specific vehicle models, ensuring optimal performance and durability. Constructed entirely from corrosion-resistant stainless steel, this muffler offers superior longevity compared to traditional aluminized alternatives. Its design features an internal drainage system that effectively reduces moisture accumulation, thereby minimizing the risk of corrosion over time. The muffler's internal partitions and mechanically joined tubes are meticulously designed to accommodate expansion and contraction during temperature fluctuations, which helps in minimizing distortion and enhancing structural integrity. Spun-locked heads and OE-style spot welds further contribute to the muffler's stability and extended service life. For acoustic performance, the muffler incorporates OE-style louvered tubes that effectively lower noise levels, while OE-style domed heads assist in reducing radiated noise, delivering a premium factory-style sound quality. The muffler's design has been validated through rigorous acoustic and flow testing, ensuring it meets the quality standards expected from original equipment. Additionally, the muffler comes with Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound® Guarantee, providing added assurance of its quality and reliability.
