Which elements must be checked in the exhaust system?

The correct choice highlights the importance of inspecting exhaust pipes and mounting brackets as critical components of the exhaust system. During a thorough inspection, the integrity and condition of the exhaust pipes must be assessed to ensure there are no leaks, corrosion, or damage that could affect the vehicle’s emissions and performance. Additionally, mounting brackets secure the exhaust pipes and muffler to the vehicle; if these are loose or broken, it can result in excessive noise, misalignment, or increased emissions.

The inspection aims to ensure that the exhaust system is functioning properly, minimizing harmful emissions and ensuring safety. Any failures in this system could lead to unsafe conditions for both the vehicle and the environment. Therefore, a detailed assessment of the exhaust pipes and mounting brackets is essential for compliance with safety regulations and maintaining the vehicle's overall efficiency.
