The Walker Exhaust 54315 is a high-quality exhaust muffler assembly designed specifically for the 1998-2005 Subaru Forester. This assembly features a 46.25-inch overall length, a 9-inch body diameter, and a 7-inch body height, ensuring a precise fit and optimal performance for these vehicle models. Constructed with 100% stainless steel, the muffler offers superior corrosion resistance compared to traditional aluminized mufflers, extending its service life and maintaining exhaust system integrity over time. The internal drainage system effectively reduces moisture collection, further enhancing durability. Designed for easy installation, the 54315 assembly serves as a direct-fit, bolt-on replacement, eliminating the need for specialized fabrication or welding. It incorporates OE-style hangers, brackets, and pipe routings, facilitating a straightforward installation process. The muffler's internal partitions and mechanically joined tubes allow for expansion and contraction during temperature fluctuations, minimizing distortion and ensuring long-term stability. Spun-locked heads and OE-style spot welds provide additional structural integrity, contributing to the assembly's overall durability. For acoustic performance, the 54315 utilizes OE-style louvered tubes to lower noise levels and OE-style domed heads to reduce radiated noise, delivering a premium factory-style sound quality. Acoustic and flow testing validate the design, ensuring reliable OE-style sound performance. The assembly comes with Walker's limited lifetime warranty and an exclusive 90-Day Safe and Sound® Guarantee, offering confidence in its quality and performance.
