2. To save fuel

3. To prevent carbon monoxide poisoning and noise

4. To ensure the engine runs at peak performance

The correct answer is: To prevent carbon monoxide poisoning and noise

Keeping your exhaust system in good condition is crucial primarily to prevent carbon monoxide poisoning and minimize noise. The exhaust system is responsible for directing harmful gases produced during combustion away from the engine and passengers. If the system is damaged or not functioning properly, it can lead to an accumulation of dangerous gases such as carbon monoxide inside the vehicle, posing a serious health risk to occupants. Additionally, a malfunctioning exhaust system can increase noise levels generated by the engine, which can be both annoying and potentially lead to further mechanical problems over time. By maintaining the exhaust system, you ensure that harmful emissions are effectively expelled, contributing to a safer driving environment and compliance with environmental regulations. While aspects like fuel efficiency and engine performance may also be influenced by a well-maintained exhaust system, the primary concern remains the safety and health of the vehicle's occupants, which is why the focus here is on preventing carbon monoxide poisoning and managing noise.
