Product Details

The Quiet-Flow SS product line is Walker’s stainless-steel muffler family for drivers who want a replacement that matches factory-style exhaust behavior while maintaining durable construction. This muffler is built with an oval body, offset inlet and outlet configuration, and pipe-connection ends for a direct replacement on listed vehicles. It is a practical choice for restoring exhaust function on 1996-1999 Chevrolet C1500 Suburban, C2500 Suburban, K1500 Suburban, and K2500 Suburban, as well as 1996-1999 GMC C1500 Suburban, C2500 Suburban, K1500 Suburban, and K2500 Suburban. Part Number 21291 is also referenced for the same application under Anchor 2228.

What It Helps Address

  • Exhaust noise that has increased due to a worn muffler
  • Corrosion-related muffler replacement on stainless-steel exhaust systems
  • Fitment issues when replacing a specific OE-style muffler on Chevrolet Suburban or GMC Suburban models
  • Loss of factory-like exhaust tone after muffler damage or deterioration
  • Replacement needs on vehicles with offset inlet and outlet routing

Installation Notes and Tips

Verify inlet and outlet diameters, offset measurements, and overall length against the existing exhaust before installation. This muffler uses pipe-connection ends and a specific-fit layout, so alignment with the original exhaust routing is important. For welded assemblies, replace all required related parts as noted in the fitment data.
