Certified Exhaust System Inspector (CESI) The CESI puts you in the garage with real diagnostic equipment and actual vehicle exhaust components. You’ll identify leaks using smoke machines, interpret gas analyzer readings, and spot corrosion patterns that indicate imminent failure? all core tasks inspectors perform daily. Theoretical knowledge matters far less than your ability to systematically troubleshoot system failures under time constraints.
