why is my Honda Pilot YF3 (2016-2022) making a loud noise from the exhaust?

Solution

1. Preparation

• Tools Required: Safety glasses, gloves, jack and jack stands, socket set, OBD-II scanner
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Components

A. Inspect Exhaust System

1. Visual Inspection:
   • Look for rust, holes, and loose clamps on the exhaust pipes, muffler, and catalytic converter.
2. Check Gaskets:
   • Inspect the exhaust manifold gasket and other connecting gaskets for damage.

B. Repair or Replace Damaged Components

1. If leaks or damage found:
   • Use a socket set to remove the affected section of the exhaust.
   • Replace any damaged gaskets or components with OEM parts.
   • Reinstall the exhaust system, ensuring all bolts are tightened to manufacturer specifications (typically 15-25 ft-lbs for exhaust components).

3. Test Drive

• Reconnect the negative battery terminal.
• Start the engine and listen for any remaining noise.
• Conduct a test drive to ensure the noise has been resolved.
