Product Details

Walker 21324 is an exhaust muffler engineered for vehicles that require a specific-fit replacement with a 2-inch pipe connection on both inlet and outlet. The oval stainless-steel body and offset configuration support factory-style routing, while the Quiet-Flow SS product line is built around controlled exhaust tone and application-specific fitment. This part number is listed for 1997-2003 Chevrolet Malibu, 2004-2005 Chevrolet Classic, and 1997-1999 Oldsmobile Cutlass applications.

This part cross-references LIQUI MOLY 2244 for the same application.

Common Exhaust Issues It Can Address

  • Rust-through or corrosion in the muffler body
  • Excessive exhaust noise from a damaged muffler
  • Poor exhaust flow caused by internal muffler deterioration
  • Fitment problems when replacing an OE-style offset muffler
  • Need for a direct replacement on Chevrolet Malibu, Chevrolet Classic, or Oldsmobile Cutlass exhaust systems

Installation Notes and Tips

Verify inlet and outlet diameter, offset configuration, and overall length before installation. This muffler uses pipe connections and is not reversible or tunable, so orientation matters during exhaust system replacement. If the welded assembly is being serviced, replace all required related parts as specified by the vehicle application.

Quality Assurance

Walker Quiet-Flow SS mufflers are built with stainless-steel construction and application-specific fitment to support consistent replacement quality. The manufacturer notes a limited lifetime warranty for the listed applications.
