The Walker Exhaust 21910 Quiet-Flow SS Muffler is engineered to provide a precise fit and superior performance for a range of vehicles. Constructed entirely from corrosion-resistant stainless steel, this muffler offers enhanced durability compared to traditional aluminized options. Its internal drainage system effectively reduces moisture accumulation, mitigating the risk of rust and extending the component's service life. Designed for easy installation, the muffler features OE-style hangers, brackets, and pipe routings, eliminating the need for specialized fabrication or welding. This direct-fit, bolt-on replacement ensures a seamless integration with existing exhaust systems. Internally, the muffler incorporates partitions and mechanically joined tubes that accommodate expansion and contraction due to temperature fluctuations, minimizing distortion and maintaining structural integrity. Spun-locked heads and OE-style spot welds further contribute to its stability and longevity. Acoustic performance is optimized through OE-style louvered tubes that lower noise levels, while domed heads help reduce radiated noise, delivering a premium factory-style sound quality. The muffler's design has been validated through acoustic and flow testing, ensuring reliable and consistent performance. With dimensions of 26.5" in overall length, 21" in body length, 4.25" in body height, and 9.75" in body width, the Walker Exhaust 21910 Quiet-Flow SS Muffler is a robust and efficient solution for maintaining optimal exhaust system function and sound quality.
