Modern exhaust systems consist of far more than simple plumbing that helps route harmful gases from your engine to your tailpipe. The exhaust system on any relatively new car will consist of numerous parts to help reduce (or shape) noise, increase safety, reduce emissions, and even provide your car's computer with critical engine management data.
Because modern exhaust systems are so complex, problems can often have unexpected consequences. Ignoring seemingly small issues such as minor exhaust leaks can ultimately lead to a cascade of much more expensive failures. Keep reading to learn why repairing exhaust problems is necessary to keep your car running well and prevent more costly future problems.
How Your Exhaust System Affects Your Engine
Your exhaust system is the final stop in the combustion process, so you might think it can't have much of an impact on your engine's functionality. After all, isn't your exhaust essentially a waste disposal system? While true, your engine needs to evacuate spent exhaust gases as quickly and efficiently as possible to maintain maximum power and efficiency.
To achieve this goal, automotive engineers need to balance emissions and sound control requirements with the need to minimize backpressure and maximize exhaust velocity. Problems in your exhaust system can affect any of these characteristics, throwing the system out of balance and potentially reducing how well your engine performs.
In practice, these effects can take a few forms. For example, failing catalytic converters or mufflers can reduce flow and increase backpressure, potentially damaging your engine over the long run. An exhaust leak can also pull more oxygen into the system, resulting in accurate sensor leadings and fouled components as the computer reacts to a perceived lean condition.
How to Avoid Costly Failures
The best way to keep your car running well and prevent your exhaust system from becoming a source of severe problems is to recognize and repair issues quickly. Problems with your exhaust will typically cause a few very noticeable symptoms, including:
- Ticking when starting the car while cold
- Excessively loud exhaust noises
- Noticeable exhaust smells
- Poor performance and fuel economy
- Check engine light (usually with a lean condition code)
Paying attention to these warning signs can allow you to spot exhaust leaks when they first develop. Bringing your car to a qualified exhaust shop as soon as you notice the symptoms of a leak will allow you to get the problem fixed before the symptoms of a faulty exhaust system can cause additional and costly damage to your car.
