my Skoda Octavia NFL (2020-Present) has a loud exhaust noise what's the issue

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to avoid electrical issues during repairs.

2. Inspect and Repair Exhaust System

• Inspect for Damage:
  • Use a flashlight to examine the entire exhaust system, including the manifold, pipes, muffler, and catalytic converter.
  • Look for cracks, rust, or loose connections.
• Repair or Replace Damaged Sections:
  • If you find holes or cracks, use exhaust tape for small repairs or replace the section of pipe if the damage is significant.
  • For a damaged muffler, remove the old muffler by unbolting it from the exhaust pipes and hangers, then replace it with a new one, ensuring proper alignment and secure fitting.
• Check and Replace Hangers:
  • Inspect the rubber hangers; if they are worn or broken, replace them to ensure the exhaust system is securely mounted.

3. Test the System

• After repairs, reconnect the battery and start the engine.
• Listen for any remaining abnormal noises and check for leaks by carefully feeling around the joints and pipes.
• If necessary, re-check the OBD-II codes to ensure there are no related issues.
