How long do mufflers last?

I drive a used car that was already five years old when I bought it, and it runs fine, but I’m not sure whether certain parts like the muffler are still in good shape or when I should look into replacing them. How long do mufflers last?

A typical muffler could be expected to last five to seven years with proper care and maintenance. However, other factors can have an impact on how long a muffler lasts, like rough driving conditions or exposure to salt on roads.
Since you say your car was already five years old when you bought it, it sounds like the time to replace your muffler could be approaching, but if it’s been taken care of well, or if the previous owner had already replaced it before selling it, it might not be an issue yet.
Some signs that it might be time to replace your muffler include loud noises, strong odors, or a noticeable decrease in gas mileage, so keep an eye out for those signs and consult a mechanic if you need to.
As you continue caring for your car, make sure it’s protected with the right
