Walker Heavy Duty 21467 Exhaust Muffler

Walker Heavy Duty 21467 is a specific-fit exhaust muffler built for commercial-duty applications that need direct replacement coverage and a straightforward pipe-connection layout.

Product Details

Walker Heavy Duty focuses on replacement exhaust components for hard-working on-road and off-road commercial vehicles, with engine-to-tailpipe coverage across a wide range of domestic, import, and commercial applications. The 21467 muffler follows that approach with a direct-fit layout, 20-inch overall length, 12-inch body length, and 7-inch body width and height. Its regular-grade steel construction and aluminized finish are suited to exhaust system replacement where the original muffler has worn, rusted, or lost performance.

This part cross-references Anchor 3618 for the same application. It also cross-references M-150 and M070028.
