What is the first step in conducting an exhaust inspection?

The first step in conducting an exhaust inspection is to remove all shrouds and shields from the muffler and stacks. This initial action is critical because it allows for a complete and unobstructed examination of the exhaust components. Accumulated debris, dirt, or corrosion may be hidden beneath the covers, potentially leading to missed defects or issues that could affect the exhaust system's overall function.

By removing these protective coverings, you gain access to the components that need to be inspected, including the integrity of the muffler and exhaust stacks. It also provides an opportunity to check for physical damage or wear that could lead to exhaust leaks, performance issues, or increased emissions. Starting the engine or checking for leaks may be subsequent steps in the inspection process, but they cannot be effectively performed without first exposing the exhaust system.
