Solution

1. Preparation

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

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before crawling underneath.

3. Inspect the Exhaust System

Visually examine the entire exhaust system from the manifold to the tailpipe for cracks or loose connections.
Pay special attention to joints, welds, and areas around the catalytic converter.

4. Repair or Replace Damaged Components

If a crack or hole is found:
- For minor leaks: Use exhaust repair tape or high-temperature sealant.
- For significant damage: Remove the damaged section using a socket set and replace it with a new pipe or manifold.
Ensure all connections are tightened to the manufacturer’s torque specifications.

5. Reassemble and Lower the Vehicle

Reinstall any components removed during inspection.
Lower the vehicle carefully and reconnect the battery.
