Typical Lifespan of a Car Muffler

A car muffler helps to muffle the sounds an exhaust system and its catalytic converter make when a car is accelerating. Essential to a comfortable driving experience, the muffler also reduces noise pollution.

How Long Will a Muffler Last?

The lifespan of a muffler varies due to the car model and the overall car use. Cars that are on the road more will experience more wear and tear to the undercarriage of the vehicle. Typically, a car muffler will last 40,000 to 80,000 miles or around two to four years. Those living in wet, snowy, and icy conditions can see an even shorter muffler lifespan.

Signs You May Need a New Muffler

If you begin to hear your car’s engine and exhaust system more than in the past, it might be time to have your car muffler examined. Rattling noises and loud sounds from the back or undercarriage of the car might also be signs your muffler is ready to be replaced.

A car muffler helps make your car a much more pleasurable machine to drive—both for you and for your fellow drivers on the road.
