If you recently added a muffler to your exhaust system, then you must be enjoying the benefits that come with the accessory such as reduced engine noise and lowered exhaust emissions. The best part is that a muffler will help you to pass a state emissions certification testing when the time comes. While quality mufflers are made from highly robust material such as aluminium, steel, or fibreglass, the mufflers aren't infallible. Therefore, you must monitor your muffler for signs of malfunction because waiting too long always leads to costly repairs. However, it is challenging if you cannot tell whether your car's muffler has a problem. This article highlights some common signs of a malfunctioning muffler.
Roaring or Rattling Noise — One of the most obvious signs that your vehicle's muffler has a problem is a sudden change in its volume. It is because the primary function of a good quality muffler is to dampen the noise that is produced by the exhaust system. Your muffler should, therefore, operate quietly in the background if it is in good condition. However, if you notice a sudden change in volume — from relatively quiet to rattling noise — then it is a glaring sign that your muffler is not performing optimally. The roaring noise is a tell-tale sign that something is wrong with the system, and if the issue is not examined in time by a qualified mechanic, then subsequent repairs will be costly.
Water Dripping from Multiple Spots — Since condensation occurs naturally in most mufflers, manufacturers include a small drain hole to allow condensed water to drain from the part. However, that does not mean that you should not check for water drips on your muffler. If you notice water dripping from the muffler's drain hole alone, then the muffler is in good condition. However, if there are water drips on several spots, then it is a clear sign that you have a faulty muffler. The numerous drip points might be caused by rust, and the decision to replace or repair the muffler depends on the severity of the rusting.
Foul Exhaust Smell — As mentioned earlier, mufflers are meant to lessen exhaust emissions from an exhaust system to the atmosphere. When in excellent working condition, your muffler will funnel exhaust gases away from the vehicle thereby leaving your car smelling fresh. However, if you smell gas or other exhaust fumes, then you need to contact your mechanic. Foul exhaust fumes inside and around the vehicle are an indication of a malfunctioning muffler. It is the most dangerous problem of a silencer and should be treated with the seriousness it deserves.
