Rumble from Down Under (Muffler Replacement)
Posted September 21, 2025 2:15 AMWe’ve all noticed them at one time or another on the street: a car or truck that drives by and the deep roar from their exhaust system sounds like a drag racer on the line. But what happens when that rumble is coming from under YOUR vehicle? Well, it could be a sign your muffler needs attention.
You may notice other signs if your muffler needs to be replaced. Your fuel economy may have plummeted, the smell of exhaust is blowing into your cabin, or your engine isn’t running in its usually smooth manner. Or you may notice your vehicle’s temperature gauge is showing it’s running hotter than usual.
Mufflers sit under your vehicle, so they are exposed to all sorts of nasty things every day, and every season. It may be dirt or salt from the road that gets kicked up on it, or you may rough it up with the potholes and speed bumps on the road. Also, moisture from rain and snow combined with chemicals and brine can literally dissolve your muffler and other components of your exhaust system.
When you start to notice one or more of these signs, it’s time to head on over to have one of our technicians look at your exhaust system. Under normal conditions, mufflers may last anywhere from five to seven years. But when they start to go, to ensure your vehicle runs the way it should, you should have your muffler (and the rest of the components in the exhaust system) inspected and replaced if necessary.
Ideally, it makes sense to have your muffler and exhaust system inspected regularly when you have other routine maintenance done to your vehicle, such as oil changes and tire rotations. That way, you can know sooner rather than later that your muffler is on its last legs before your (noisy) vehicle begins to draw the wrong kind of attention from other drivers.
