Exhaust System Problems

Exhaust system problems shouldn’t be left untreated because they can pose a risk to your health, as well as the environment. Not to mention that the efficiency of your car’s engine may decrease if it’s unable to properly expel combustion byproducts. Below are some of the signs that your exhaust system may need servicing or repair:

  • Loud rumbling sound
  • Smell of exhaust inside the cabin
  • Excessive exhaust
  • Unusual vibrations that may indicate an exhaust leak

Catalytic Converter Repair

The job of a catalytic converter is to reduce the amount of toxic pollutants in the gasses that exit your vehicle. Over time, your catalytic converter may become clogged and fail, which often sounds like someone is shaking a box of rocks. This will also cause you to fail your Maryland emissions test. At Hillmuth Auto Care, we can suggest the best ways to fix your failed catalytic converter, as well as repair the underlying cause.

Muffler Repair

A muffler muffles the sound of passing exhaust gasses, so if it fails to do its job, you will notice that your car becomes louder. Because the muffler essentially sits in the open and gets a beating from the elements, it’s prone to rusting and may develop holes and even fall off. Whether it comes to replacing your old muffler or welding it back in place, our Maryland auto repair experts will be happy to help.

Schedule your exhaust system repair appointment today at one of our locations in Gaithersburg, Columbia, Glenwood or Clarksville.
