If you drive an older vehicle, chances are you’ve already spent a fair amount of time and money keeping it in good repair. Understanding the problems that are unique to older vehicles, however, can help you take the necessary precautions and prevent more expensive repairs down the road. Here are some common problems that can affect exhaust systems on older vehicles:


If you drive an older vehicle, rust is an ever-present threat to your exhaust system. While a small amount of rust may not cause any major problems, rust can cause serious damage to your exhaust system over time. For example, rusted components are more liable to crack. In order to prevent rust from ruining your car’s exhaust system, it is important to have your mechanic regularly inspect your exhaust system. This way, small amounts of rust can be taken care of before the problem becomes too serious.


Another potential problem for older exhaust systems is leaks. Leaks occur when components of your exhaust system crack or break. In addition to ruining the exhaust system, leaks also pose a health risk to you and your passengers, as toxic fumes may make their way into the car. If you notice the scent of exhaust fumes inside of your car, you should take your car to a mechanic as soon as possible, as it may be a sign of a leak.

Catalytic Converter Malfunction

Your car’s catalytic converter is important because it helps prevent toxins created by the combustion process from getting into the air. When you drive an older vehicle, your catalytic converter has a higher chance of failing. If this happens, your vehicle will not be able to pass an emissions test.

Older vehicles can be an enthusiast’s dream thanks to their style and performance. However, keeping an old car in good shape does require extra care, particularly when it comes to the exhaust system.
