Walker 22967 Exhaust Muffler

Overview

Walker Heavy Duty muffler 22967 is a universal exhaust muffler built for commercial and on/off-road applications. It uses a round steel body with an aluminized finish and center pipe connections for a straightforward exhaust layout.

With 4-inch inlet and outlet diameters and a 39.75-inch overall length, this muffler is suited for custom exhaust work where a durable replacement component is needed. Walker 22967 is part of Walker’s Heavy Duty line, and the brand’s broad emissions-control coverage supports a wide range of replacement needs.

Key Features

• Universal-fit exhaust muffler for custom or replacement exhaust builds
• Round steel construction with aluminized finish for added corrosion resistance
• 4-inch center inlet and 4-inch center outlet pipe connections
• Combination muffler design for commercial and hard-working vehicle applications
• Walker Heavy Duty product line for demanding exhaust service

Product Details

Walker 22967 is an exhaust muffler designed around a round, steel-bodied construction with pipe connection inlet and outlet ends. The aluminized finish adds protection against exhaust-system wear, while the center inlet and outlet configuration supports direct routing in universal exhaust setups. This part cross-references AMS Automotive 4218 and M100845 for the same application.

Because this is a universal muffler, fitment depends on the exhaust system layout rather than a specific vehicle listing. It is a practical choice for repair shops and installers working on commercial exhaust systems, custom fabrication, or replacement of an existing muffler with matching dimensions and connection sizes. Walker 22967 is also identified by part number 22967 for ordering and reference.

Common Uses

• Replacing a worn or rusted exhaust muffler
• Restoring exhaust flow after muffler damage or internal failure
• Matching a 4-inch pipe connection in a custom exhaust system
• Addressing exhaust noise from a deteriorated muffler body
• Supporting commercial vehicle exhaust repairs

Installation Notes

Verify inlet and outlet diameter, overall length, and available space before installation. Confirm center-in/center-out routing matches the existing exhaust layout, and compare the muffler body dimensions to the vehicle’s exhaust packaging. Professional exhaust fitting is recommended for universal applications.

Quality Assurance

Walker positions Heavy Duty products within its broader engine-to-tailpipe emissions-control lineup, giving this muffler the backing of a manufacturer focused on replacement exhaust components for domestic, import, and commercial applications.
