How often do I need to change the muffler on my car?

January 03, 2018

Mufflers are not on a scheduled maintenance interval like oil changes. They often last 100,000 kms or so, but this depends on the specific vehicle and driving conditions. Inspect the muffler for rust holes or lightly tap on the bottom of the muffler with a hammer. If you hear debris/rust bouncing around inside the muffler it is time for replacement.
