The Walker Exhaust 21532 Quiet-Flow SS Exhaust Muffler is engineered to enhance the performance and longevity of your vehicle's exhaust system. Constructed entirely from corrosion-resistant stainless steel, this muffler offers superior durability compared to traditional aluminized options. Its design features an internal drainage system that effectively reduces moisture accumulation, thereby extending the component's service life. The muffler's internal partitions and mechanically joined tubes accommodate thermal expansion and contraction, minimizing distortion and ensuring structural integrity over time. Spun-locked heads and OE-style spot welds further contribute to its robust construction, providing stability and a longer operational lifespan. Acoustic performance is optimized through 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 design approach ensures that the muffler not only meets but exceeds original equipment standards. Installation is straightforward, thanks to its direct-fit bolt-on design, which includes OE-style hangers, brackets, and pipe routings. This eliminates the need for specialized fabrication or welding, facilitating a hassle-free replacement process. The muffler's dimensions—3.25" in height, 7.75" in width, and 18.00" in length—make it suitable for a wide range of vehicle applications. With an inlet and outlet diameter of 2.00" and an offset configuration, it offers versatility in fitment. Backed by Walker's limited lifetime warranty and exclusive 90-Day Safe and Sound® Guarantee, the 21532 Quiet-Flow SS Exhaust Muffler provides both reliability and peace of mind for fleet operators seeking to maintain optimal vehicle performance.
