Product Details

The Walker Quiet-Flow SS line is built for drivers who want a direct-fit replacement muffler with stainless-steel construction and controlled exhaust tone. Part Number 22673 is shaped as an oval combination muffler with a 3-inch inlet and 3-inch outlet, plus offset pipe connections to match the listed applications. It is compatible with 1990-1995 Chevrolet C3500 and K3500, and 1990-1995 GMC C3500 and K3500 models below 15,000 lb GVW with catalytic converter-equipped premium configurations.

Common Problems This Muffler Can Address

• Rust or corrosion in the original muffler body
• Exhaust noise increase from a worn internal muffler core
• Poor fitment from a previous repair or welded replacement
• Restricted exhaust flow caused by internal deterioration
• Need for a direct replacement on select Chevrolet C3500, K3500, GMC C3500, and K3500 trucks

Installation Notes and Tips

Verify the vehicle’s year, make, model, GVW rating, and catalytic converter configuration before ordering. This muffler uses pipe connections with offset inlet and outlet placement, so the existing exhaust layout should be matched carefully during installation. If the vehicle has a welded assembly, replace all required parts in the assembly as noted in the fitment data. Professional exhaust installation is recommended for proper alignment and sealing.
