Installation Notes and Tips

Verify inlet and outlet flange alignment before installation. This muffler assembly uses a 2.375-inch inlet outside diameter and a 2.125-inch outlet outside diameter with 2-bolt welded flange connections, so matching the existing exhaust layout is important for proper fit. For 2001-2003 Toyota Sienna front applications, the notes specify use with Part Number 36380.

Confirm vehicle year, make, model, and front-position exhaust configuration before ordering. Because this is an OE-style replacement muffler assembly, accurate fitment matching helps reduce installation time and exhaust alignment issues.

Quality Assurance

Walker Quiet-Flow SS muffler assemblies are built with stainless-steel construction and direct-fit OE-style replacement geometry. The manufacturer notes a limited lifetime warranty for the listed Toyota Sienna application.
