Exhaust System: Testing and Inspection

Exhaust System, Checking For Leaks
- Start engine and run at idling speed.
- Plug tailpipe (e.g. with rag or stopper) and leave plugged until check is complete.
- Listen for noise at connection points (cylinder head/manifold, manifold/turbocharger, turbocharger/catalytic converter, etc.) to locate any leaks.
- Correct any leaks that are found.
