What Does My Car's Exhaust System Do?

Your vehicle's exhaust system is very important. It expels dangerous fumes away from the engine as well as the inside of the vehicle. These toxic fumes are sent through the catalytic converter which turns the fumes into less dangerous gasses that are acceptable for emission standards. Then the fumes go through the muffler and are finally expelled into the outside air.

Your vehicle's exhaust system is made up of many parts and if just one part is broken or compromised, the whole system won't work as it should. When it comes to your exhaust system, problems can put you in severe danger so if you notice any of the symptoms of a failed exhaust system, it is very important to get your vehicle checked out by a qualified professional.

  • Strange Smells
    If you smell something burning or a gas leak, this could be a sign that you are having problems with your exhaust system. A burning smell could indicate that your gasket has failed. The burning smell you are noticing is a result of the heat from the exhaust gases leaking into your engine bay, causing plastic parts and wiring to burn. A gas smell coming from inside your vehicle could be another sign that you are having exhaust problems. This happens when there is a broken pipe somewhere and gas ends up leaking out, sometimes going inside your car.
  • Vibrations
    When you are driving your vehicle, your car might begin to vibrate as a symptom of exhaust problems. You might notice the vibrations in the brake pedal or the steering wheel, however your vehicle shouldn't vibrate under normal circumstances. If your entire car is vibrating, that is a good sign that you have very serious issues with your exhaust system and it's a good time to book an appointment with a mobile mechanic.

  • A Hanging Or Dragging Exhaust Pipe
    This is a more noticeable problem, but your exhaust pipe should never drag on the ground. If your exhaust pipe is hanging lower than it normally does or it is dragging on the ground, you need to get it checked our by a qualified professional. If you continue driving with an exhaust pipe that is dragging on the ground, it could break off of your car completely and hit a car behind you.
  • Abnormal Exhaust Smoke
    If you notice your car is producing a lot of smoke, this could be an indicator that you are having exhaust problems. The color of the smoke could even tell you exactly what is going on. The most common colors are blue, black, and white/gray. To learn more about what these colors mean or why your car is smoking, click here and read our blog post.
  • Visible Rust
    Rust on your car can be very dangerous if it isn't taken care of properly. If you usually take shorter trips in your car rather than driving longer distances, your vehicle's exhaust system may be more likely to rust. That's because short trips allow the water to collect, but it doesn't ever get hot enough to evaporate off. Water droplets sitting in one spot for a long period of time can cause rusting. Eventually this rust will ruin your exhaust system, so if you see any visible rust, you need to book an appointment with a professional.
  • Decreased Fuel Efficiency
    One of the biggest reasons besides safety to get your exhaust problems fixed is because they can  decrease your vehicle's fuel efficiency. This means it takes more fuel to get your car working which means you will end up making more trips to the gas station. If you don't get your vehicles exhaust problems fixed in a timely manner, you could end up wasting a lot of money due to the decreased fuel efficiency.
