Installation Instructions

Installation of the Walker Quiet-Flow SS 22460 muffler is designed to be a direct-fit replacement. Professional installation is recommended. Always prioritize safety by wearing appropriate personal protective equipment (PPE) and working in a well-ventilated area.

Required Tools and Materials:

• Vehicle lift or jack stands
• Wrenches/sockets
• Penetrating oil
• Exhaust hanger removal tool (optional)
• Safety glasses and gloves
• New exhaust clamps (if not reusing existing ones)

Procedure:

1. Prepare Vehicle: Safely lift the vehicle using a lift or jack stands. Ensure the vehicle is stable. Allow the exhaust system to cool completely before beginning work.
2. Locate Existing Muffler: Identify the current muffler and its connection points to the exhaust pipes and hangers.
3. Apply Penetrating Oil: Apply penetrating oil to all bolts, nuts, and hangers that need to be removed. Allow time for the oil to penetrate.
4. Remove Old Muffler:
   • Loosen and remove any clamps or bolts securing the muffler to the exhaust pipes.
   • Carefully detach the muffler from its hangers. An exhaust hanger removal tool can assist with this.
   • Remove the old muffler from under the vehicle.
5. Inspect and Prepare: Inspect the surrounding exhaust components for any damage or excessive corrosion. Clean any mating surfaces if necessary.
6. Install New Muffler:
   • Position the new Walker Quiet-Flow SS 22460 muffler under the vehicle.
   • Attach the muffler to the existing exhaust hangers.
   • Connect the muffler to the exhaust pipes using new or appropriate clamps/bolts. Ensure a secure and leak-free connection.
   • Align the muffler to ensure proper clearance from other vehicle components.
7. Tighten All Connections: Systematically tighten all clamps and bolts to the manufacturer's recommended torque specifications.
8. Final Inspection: Lower the vehicle and start the engine. Check for any exhaust leaks by listening for hissing sounds or feeling for escaping gases. Address any leaks immediately.

Maintenance

The Walker Quiet-Flow SS 22460 muffler is constructed from 100% stainless steel, offering superior corrosion resistance and requiring minimal maintenance. Regular inspection of the exhaust system is recommended to ensure longevity and proper function.

Recommended Maintenance Checks:

• Visual Inspection (Annually or during oil changes):
  • Check for any signs of physical damage, dents, or cracks on the muffler body and pipes.
  • Inspect all welds and connections for integrity.
  • Examine hangers and mounting points for wear, corrosion, or looseness. Replace worn hangers as needed.
  • Look for rust or corrosion on other exhaust components. While the muffler is stainless steel, other parts of the exhaust system may not be.
• Listen for Abnormal Noises: Pay attention to any changes in exhaust sound, such as increased loudness, rattling, or hissing, which could indicate a leak or a loose component.
• Address Leaks Promptly: If an exhaust leak is detected, have it repaired immediately. Leaks can affect engine performance, fuel efficiency, and introduce harmful gases into the vehicle cabin.
