Many car owners don’t necessarily know the interworkings of their vehicles. While it may not be necessary to know all the details, you should know enough to be able to identify when it’s having problems and needs a professional to take a look at it. Your muffler, for example, is vital to your car’s exhaust system. It reduces emissions and dampens noise. If you notice your car is making more noise than usual, you may need car muffler repairs. Unfortunately, just like any other part of your vehicle, your muffler can degrade over time. When it’s not working properly, the fuel efficiency of your vehicle may not be ideal and can cause your engine to misfire.
