Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and cool.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Repair Exhaust Components

Exhaust System Inspection
- Use a jack and jack stands to lift the vehicle safely.
- Inspect the entire exhaust system from the manifold to the tailpipe for cracks, holes, or loose connections.
Repair or Replace Faulty Parts
- If any damage is found, replace the affected component (e.g., muffler, pipes, or gaskets).
- For muffler replacement, remove the old muffler by cutting or unbolting it from the exhaust pipes, then install the new muffler using appropriate clamps or welding.

3. Secure Exhaust System

Check and Replace Hangers
- Inspect all rubber hangers for wear. Replace any that are cracked or broken.
- Ensure the exhaust system is properly aligned and secured to prevent movement that can cause noise.

4. Reassemble and Test

Reconnect any components that were removed during inspection.
Reconnect the battery.
Start the vehicle and allow it to idle, checking for any remaining noise.
