The Walker Exhaust 55573 18" x 9" x 7" Stainless Steel Exhaust Muffler Assembly is engineered to provide a durable and efficient solution for your vehicle's exhaust system. Constructed with 100% stainless steel, this muffler offers superior corrosion resistance compared to traditional aluminized mufflers, ensuring a longer service life. The internal drainage system effectively reduces moisture collection, further enhancing durability. Designed for easy installation, it features OE-style hangers, brackets, and pipe routings, eliminating the need for specialized fabrication or welding. The muffler's internal partitions and mechanically joined tubes allow for expansion and contraction during temperature changes, minimizing distortion and ensuring consistent performance. Premium acoustic control is achieved through OE-style louvered tubes that lower noise levels, while OE-style domed heads help reduce radiated noise, delivering a factory-style sound quality. Acoustic and flow testing validate the internal muffler design, ensuring reliable performance. This muffler is compatible with various vehicle models, including the 2006-2014 Honda Ridgeline, providing a direct-fit replacement that performs like original equipment.
