A car that suddenly seems much louder than usual may have a hole in the muffler or elsewhere in the exhaust system.
Lithia Auto Stores offers tips online about what to do if you sense an exhaust issue.
A hole in the muffler could be a simple and fast repair, but the entire exhaust system should be checked just in case there are other holes or cracks. The metal that makes up the exhaust system is affected by road salt, chemicals and dirt and debris simply from exposure as you drive the vehicle. Over time, that metal corrodes and eventually develops holes or cracks. If you hear loud noises or smell exhaust inside the vehicle, it's time to get the car checked out by Lithia Auto Stores or your local service location.
The exhaust system also helps reduce emissions. A problem in the exhaust line could mean the vehicle will fail an emissions inspection, which means repairs are necessary to pass the test. Many states have laws requiring emissions tests, particularly for older vehicles.
