What to look out for : Problems with my Exhaust or Silencer?

Key points

1. Loud Roaring Noises

Some of the first signs of a bad silencer are loud or strange noises coming from your vehicle.


 If your silencer begins to produce loud noises, it usually means it’s suffered damage. A compromised silencer can cause the pre-muffled exhaust in your system to leak out and typically results in thumping, clanking or rattling noises in your exhaust pipe.


In the average undamaged or new silencer, engine exhaust travels through it until it gets to the chamber – the area that helps reduce the magnitude of the vibrations caused by the sound. This is what gives a silencer its sound-dampening qualities.


However, in the event of silencer problems, these vibrations will not be able to properly travel through the tubes and perforations that catch the sound, causing a series of loud, roaring noises every time you get behind the wheel.


You’re better off picking up a performance muffler if you’re looking to make your exhaust louder.


2. A Noticeably Bad Smell


One of the most significant warning signs you’re experiencing silencer problems is a noticeably foul smell 


coming from your vehicle when driving. As a component of your exhaust system, one of the silencer’s primary functions is to filter exhaust gases and harmful fumes out of your car. If your not-so-new silencer isn’t filtering these fumes correctly due to a leak or damage, it could cause them to become trapped within your vehicle.


If you smell a foul odor, you must get your silencer checked out immediately. This is one of the most crucial bad muffler symptoms to catch early.

3. A Drastic Decrease in Fuel Economy

A fully functional or new silencer can contribute to a much higher fuel economy when paired with a great exhaust system.


One of the common signs of muffler problems is decreased Fuel Economy.


 Holes or obstructions clogging up your muffler can disrupt the flow of exhaust coming out of your vehicle, and exhaust leaks commonly affect the engine’s O2 sensors.


If you find you’re taking more trips to the fuel station than usual, you’re likely experiencing bad muffler symptoms. If your silencer is the problem, getting a silencer replacement or silencer will help filter your exhaust more efficiently and bring your fuel economy back up.


4. Rust Damage

You can also identify the signs of a bad silencer by examining its physical condition.


Common bad silencer symptoms include dripping and signs of rust damage 


if you see either, the damage to your silencer is likely pretty extensive.


It’s important to note that a small amount of rust on the surface is normal as long as it doesn’t seem to penetrate the metal. However, a considerable amount of rust is usually an indicator of silencer problems and will cause further complications.


In addition, some manufacturers outfit their vehicles with a small drain hole in the silencer, so small amounts of dripping liquid aren’t a cause for concern. 


You should consider silencer replacement when the dripping is extensive or stems from multiple locations.


5. Frequent Engine Overheating & Misfires


Vehicle engines are sturdy fixtures. If given proper care, they can withstand years of near-constant use.

Nevertheless, your engine’s continued functions rely heavily on its many moving components working together.


 If you’re experiencing bad silencer symptoms, your vehicle is likely to misfire or overheat.


A damaged silencer can cause blockages in your exhaust system, which result in abnormally high engine temperatures or a complete loss of power.


If you suspect you’re having silencer problems, turn your vehicle on and let it idle for a few minutes. If you see your temperature gauge jump up to high levels, you’ll need a silencer replacement immediately.


When to Replace a silencer

How long does a silencer last? Most new silencer last 40,000 to 80,000 miles, or two to four years, depending on your driving conditions and your vehicle’s make and model.


However, if you live and drive in wet climates, such as along a coastline with salty ocean air or in an area that experiences heavy snowfall and constantly salted roads, you’ll see an even shorter lifespan.


If you’re closing in on this timeframe or you notice your silencer is showing any of the above-mentioned bad muffler symptoms, it’s time to think about silencer replacement or repair. But don’t worry too much. 


If you catch the signs of a bad silencer early on, silencer replacement is relatively inexpensive and will keep your vehicle running as it should.


If you notice you’re having silencer problems and don’t act on them, more extreme issues will develop over time, and you’ll be forced to spend more money on more extensive repairs.
