The exhaust system of the vehicle plays an important role in the proper operation and safety for the vehicle. Mufflers that are damaged can affect how the vehicle performs. Also, corroded pipes or holes in the system could cause issues for how the vehicle drives and performs. Knowing when there are first signs of issues with the vehicle can help to prevent further wear for other parts. It can also help decrease the chance for a costly repair bill. Some signs of exhaust problems could include fumes inside the passenger compartment of the vehicle. It can also cause a decrease in fuel efficiency of the vehicle. Another sign could be any unusual sounds or noises that come from the engine or muffler of the vehicle. This can be especially noticeable whenever the vehicle is running. Rough idling could also indicate an issue with the exhaust system. No matter what the symptom is, make sure to bring the vehicle in so we can inspect it. Fuel Efficiency Decreases The exhaust system will vent the gasses from the engine so that the vapors are passed through the back of the vehicle effectively. If there is a start of an issue with the exhaust system, you may notice a decrease in fuel efficiency with your vehicle. The engine may also require more fuel in order to reach the proper pressure point. This could increase the amount you spend at the pumps each time. Fumes that might be Inside the Vehicle If there is an issue with the exhaust system, one of the warning signs could be that there is a fume leak. This could then start to leak into the passenger compartment of the vehicle. The fumes will have an unpleasant odor to them. If you notice fumes leaking, make sure to bring the vehicle in so we can inspect it as soon as possible. Loud Sounds or Noises from the Vehicle If you notice any noise that is made by the exhaust, there may be damage to the system. When the baffling in the muffler gets worn down, the sound of the engine may get louder. It may also become more noticeable when the vehicle is operation. An inspection of the vehicle is recommended to ensure the safety of it. Odd Noises from the Mufflers Another warning sign of an exhaust problem could be an issue with the pipes or muffler of the vehicle. If there is a popping or hissing noise that is unusual, there could be an issue with the mufflers. If these noises are becoming more frequent, make an appointment to bring the vehicle in for an inspection. The Vehicle Idles Roughly Rough idling can be an indication that there is a problem with how the vehicle performs. If the vehicle does not idle properly, it will use more fuel than it should and become inefficient. Over time, rough idling could lead to more serious problems, as well as a costly repair bill.
