The Walker Exhaust 21544 Quiet-Flow SS Exhaust Muffler is engineered to provide a direct-fit replacement for specific Jeep models, including the 2005-2010 Jeep Grand Cherokee and the 2006-2010 Jeep Commander. Constructed entirely from corrosion-resistant stainless steel, this muffler offers superior durability compared to traditional aluminized alternatives. Its internal drainage system effectively reduces moisture accumulation, thereby extending the component's service life. Designed for straightforward installation, the muffler features OE-style hangers, brackets, and pipe routings, eliminating the need for specialized fabrication or welding. The internal design incorporates partitions and mechanically joined tubes that accommodate expansion and contraction due to 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. 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. The muffler's dimensions are as follows: overall length of 32 inches, body length of 27 inches, body width of 11 inches, and body height of 5.5 inches. The inlet has an inside diameter of 2.5 inches with an offset of 3.5 inches, and the outlet has an inside diameter of 2.25 inches located at the center. This design ensures a precise fit and reliable performance for the specified vehicle applications.
