Your Exhaust System and Its Possible Problems

When people think of a car’s exhaust system, they usually think of the muffler. But there are other components to the exhaust system, and over the years, automakers have developed more and more sophisticated ways to increase efficiency, reduce noise, and limit emissions. Your exhaust system includes your muffler, piping, and a catalytic converter, which reduces pollution. Generally speaking, exhaust systems are resilient, and problems that arise with them are often a sign that something else in the vehicle isn’t working properly. Still, it’s important to be vigilant about possible exhaust problems.

Signs of an exhaust system or muffler problem include:

  • Excessive loud noises while driving
  • Engine misfires
  • Gasoline odors
  • Decrease in acceleration or power
  • Decrease in fuel efficiency
