3. Installation Instructions

3.1 General Guidelines

• Always ensure the vehicle is cool before beginning work on the exhaust system.
• Use appropriate safety gear, including eye protection and gloves.
• Support the vehicle securely on jack stands or a lift. Never work under a vehicle supported only by a jack.
• Apply penetrating oil to rusted fasteners prior to removal to ease the process.
• Ensure proper ventilation if working in an enclosed space.

3.2 Step-by-Step Installation

1. Preparation: Locate the existing exhaust pipe section that needs replacement. Identify all connection points, hangers, and clamps.
2. Removal of Old Pipe: Carefully remove the old exhaust pipe. This may involve unbolting flanges, cutting pipes, or loosening clamps. Be mindful of any sensors or wires attached to the exhaust system.
3. Fitment Check: Before final installation, dry-fit the new Walker 44066 exhaust pipe to ensure it aligns correctly with the existing exhaust components and hangers. The pipe is manufactured with precision bends and OE-style routings for a direct fit.
4. Installation: Secure the new pipe using appropriate clamps or by welding, depending on your preferred installation method. Ensure all connections are tight and leak-free.
5. Secure Hangers: Attach the pipe to all factory hangers to ensure proper support and prevent rattling.
6. Final Inspection: After installation, start the vehicle and check for any exhaust leaks. Listen for unusual noises or vibrations.

4. Maintenance

To ensure the longevity and optimal performance of your Walker exhaust pipe, regular inspection is recommended. Periodically check the following:

• Corrosion: Inspect the pipe for signs of rust or corrosion, especially in areas exposed to road salt or moisture.
• Leaks: Check all connections (welds, clamps, flanges) for exhaust leaks, which can indicate loose fittings or cracks.
• Hangers: Ensure all exhaust hangers are intact and securely holding the pipe in place to prevent excessive movement and rattling.
• Damage: Look for any physical damage, such as dents or cracks, which could compromise the pipe's integrity.

Addressing minor issues promptly can prevent more significant problems and extend the life of your exhaust system.

5. Troubleshooting

This section addresses common issues you might encounter with an exhaust pipe.

5.1 Common Issues and Solutions

• Loud Exhaust Noise: This often indicates an exhaust leak. Inspect all connections and the pipe itself for cracks or holes. Tighten clamps or repair/replace damaged sections.
• Rattling or Vibrations: This can be caused by loose or broken exhaust hangers, or the exhaust pipe making contact with the vehicle's undercarriage. Check all hangers and adjust the pipe's position if necessary.
• Exhaust Fumes in Cabin: This is a serious issue and requires immediate attention. It typically points to a significant exhaust leak. Do not drive the vehicle until the leak is identified and repaired.

If you are unable to resolve an issue, it is recommended to consult a qualified automotive technician.
