Most Common Exhaust System Issues to Look Out For

A vehicle's optimum function dramatically depends on the exhaust system. The exhaust system has the responsibility of emitting gases and other combustion elements from the automotive engine. It also reduces any unnecessary sounds generated from the combustion process, making your ride stable and smooth. The exhaust system is made up of different parts that work harmoniously to achieve its purposes. These parts include:


  • Exhaust manifold
  • Oxygen Sensors
  • Catalytic converter
  • Tailpipe
  • Muffler
  • Resonator


If there is trouble with any of the components, the entire exhaust system is compromised. We have seen many types of exhaust system troubles, but these are the most common: 



The oxygen sensors work within the exhaust system to balance the mixture of air and fuel. Their defects are somewhat common, and it affects the computer engine. An abnormal air-fuel mixture balance will lead to a clogged catalytic converter. As you will notice, one malfunctioning part in the exhaust system can further lead to multiple problems. Therefore, faulty oxygen sensors need to be repaired immediately to minimize further damages.



Continuous driving on rugged roadways reshapes the durability of the exhaust system. The shaking and bumping could cause cracks in the exhaust system, leading to the leaks of poisonous gases in the main cabin. 



Rust is one of the most popular exhaust system problems, and it is caused by the accumulation of moisture from rain and snow. Over time rust forms lumps and causes physical damage to the car components. The corrosion and punctures are usually found within the muffler pipes and resonators, compromising their functionality.



Another common issue for the exhaust system is loose parts. These are easy to diagnose since you will hear rustling sounds when driving. The sounds could indicate loose brackets, a detached exhaust pipe, or a loose heat shield. Apart from an obnoxiously loud drive, the unfastened parts can cause more harm to the vehicle. 


Regular vehicle inspections are essential to ensure your car functions as it is supposed to. If you are unsure whether your exhaust system is compromised, have it diagnosed by a professional. For exhaust system repairs, visit The Auto Doc in Houston, TX today!
