Performing a visual inspection of the exhaust system is crucial for ensuring that it is functioning correctly and safely. The correct procedure involves checking for leaks, rust, and the secure mounting of components, which are all indicative of the exhaust system's integrity.

During the inspection, you would visually assess the entire exhaust system for any signs of deterioration such as rust, which could indicate that the system is compromised and may lead to leaks or failure. Leaks in the exhaust system can not only affect engine performance but can also pose serious health hazards due to the potential release of harmful exhaust gases into the vehicle's cabin or environment.

Additionally, confirming that the components are securely mounted is essential. Loose or disconnected parts can lead to increased noise, vibrations, and potential hazards on the road. By ensuring that everything is properly fastened, the likelihood of failure during operation is significantly reduced.

The other options mentioned, such as observing fuel consumption rates, monitoring engine sound levels, or evaluating the cleanliness of the tailpipe, do not directly pertain to the visual inspection of the exhaust system itself. While these factors can provide some insights into the overall health of the vehicle, they do not replace the critical visual checks required to maintain a functioning exhaust system.
