If your Toyota Sienna’s exhaust is getting loud or rusty, this Walker Quiet-Flow SS muffler assembly is a premium, direct-fit replacement. Specifically designed for 2004-2013 Toyota Sienna models, it’s made from 100% stainless steel (not just aluminized), which provides superior corrosion resistance and a longer lifespan. The part number is 47817, with a 2.25-inch inlet and 2.5-inch outlet (outer diameters). It’s engineered to bolt right on using the OE-style hangers and brackets—no cutting or welding required for most installations. Inside, louvered tubes and domed heads help reduce noise while maintaining a smooth factory-style sound and good exhaust flow. Backed by Walker’s limited lifetime warranty and 90-Day Safe and Sound Guarantee. Always double-check your vehicle’s year, make, model, and trim for compatibility before purchasing. A great upgrade for anyone wanting a durable, quiet, and hassle-free replacement muffler that’s built to last.
