One of the most important parts on your car is the muffler. Located under the rear of the car, it is essentially the exhaust system of your vehicle’s engine. The muffler helps reduce the amount of noise produced by your engine as well as also controlling the backpressure of the engine, which improves the endurance and performance of your car’s engine. Backpressure is created by the engine’s valves moving in all possible directions and colliding and cancelling each other out, with an old or poorly maintained muffler, this can have a considerable impact on your engine’s performance.
Your muffler is a key component of your car’s function. If you have a muffler that’s not functioning properly it can cause a plethora of different problems. A muffler that’s not functioning, can lead to exhaust back pressure which can cause other elements of your car to be damaged to the point that it's no longer drivable.
Here are 3 signs you need a muffler replacement:
1. Your muffler is making loud noises
The first sign that your muffler needs replacing is if you begin to hear any loud or strange noises coming from your car. One of your mufflers main purposes is to reduce the noise produced by the exhaust system, so a sudden loud noise while accelerating could mean that the muffler is no longer working.
2. A bad odor is coming from your muffler
Another warning sign that your muffler needs replacing is if you begin to smell a bad odor coming from your car. If your muffler isn’t filtering the fumes out of your exhaust correctly due to a leak or damage to the muffler, it could cause the fumes to become trapped. If you smell a foul odor it’s important to get your muffler checked out and repaired or replaced.
3. Your gas mileage has drastically decreased
A third sign your muffler needs replacement is if you notice your gas mileage decreasing. A functioning muffler helps with efficiency and a dip in efficiency could be a warning sign of a malfunctioning muffler. If this happens, it’s important to get your car checked out by a mechanic to diagnose the issue. If the issue is the muffler, getting a muffler replacement will help filter your exhaust more efficiently and help increase your gas mileage.
