Checking exhaust system for leaks
–  Start engine and run at idling speed.
–  Plug the tailpipe (e. g. with rags or stopper) and leave plugged until the check is complete.
–  Listen for noise at connection points (cylinder head/exhaust manifold, exhaust manifold/front exhaust pipe, etc.) to locate any leaks.
–  Rectify any leaks that are found.
