What can a broken exhaust system potentially allow?

A broken exhaust system can potentially allow poisonous fumes to enter the cabin of the vehicle. The exhaust system is designed to safely redirect exhaust gases away from the engine and, ultimately, out of the vehicle. If the system is compromised due to broken components, such as a cracked manifold or holes in the exhaust pipes, harmful exhaust gases, including carbon monoxide, can leak into the passenger compartment. This presents a serious health risk to the occupants, making it essential for drivers to ensure their exhaust systems are in good working condition.

While issues like excessive noise, engine overheating, and changes in fuel efficiency may also result from a faulty exhaust system, the immediate dangers associated with toxic fumes entering the cabin make this aspect one of the most critical to address when it comes to vehicle safety and driver/passenger health.
