Exhaust System Repair
A properly functioning exhaust system keeps your vehicle quiet, protects your passengers from harmful fumes, and reduces air pollution. It’s a pretty complex system. And if there are problems, it can be both noisy and embarrassing, not to mention dangerous.
Exhaust systems are sometimes referred to as mufflers, silencers, or exhaust pipes. But these are all just components of the overall system. And they’ll all last several years with proper care and maintenance. Here are some key things you need to know about your exhaust system:
- What does an exhaust system do?
- How does the exhaust system work?
- Can exhaust systems improve fuel efficiency and mileage?
- When and why should I replace my exhaust system?
What does an exhaust system do?
Your vehicle’s exhaust system has three primary functions. First, it collects the harmful exhaust gases that are produced by the engine. (These gases are also called emissions). By collecting and diverting these gases, the exhaust system prevents them from entering the passenger cabin.
Second, the system converts the collected emissions into gases that are less harmful to the environment. By reducing the toxicity of the emissions, you reduce the amount of pollutants that are released into the environment.
Lastly, the exhaust system helps to “muffle” the noise and vibrations produced by your engine. This has the effect of making your ride both quieter and more comfortable.
How does the exhaust system work?
An exhaust system works through multiple, connected components that run the entire length of your vehicle. This includes a manifold, oxygen sensors, catalytic converter, muffler, and tail pipe. And each component has its own, unique role:
Exhaust manifold – the manifold connects directly to your engine’s cylinders, which is where toxic exhaust gases are first produced. The manifold’s job is to collect and divert these emissions into an exhaust pipe. This keeps the toxins contained within the exhaust system and out of the passenger cabin.
Oxygen sensors – oxygen sensors detect the amount of oxygen that is present in your engine’s emissions. Optimal oxygen levels correspond to good fuel efficiency and lower emissions. So when these levels are either too high or too low, the sensors will send a signal back to your engine. This allows the engine to adjust the way it’s burning fuel to power your vehicle.
Catalytic converter – the catalytic converter has the job of turning your vehicle’s toxic emissions into something less harmful for the environment. It does this by converting exhaust gases into a combination of water vapour and carbon dioxide. And it uses precious metals, such as platinum and palladium, to make this chemical reaction take place. That’s why catalytic converters are among the most expensive parts in your vehicle.
Muffler – the muffler contains specially crafted chambers and tubes that help to cancel out the loud noises produced by your engine. Because of its function, the muffler is sometimes also referred to as a silencer.
Tail pipe – the tail pipe is the final component in the exhaust system and it sits at the very back of your vehicle. The job of the tail pipe is to ensure all emissions make it out of the system and into the air behind your vehicle.
Can exhaust systems improve fuel efficiency and mileage?
Your vehicle’s exhaust system does have an impact on fuel efficiency and mileage. This is because your engine’s performance is connected to the rate at which exhaust gases are able to leave your vehicle. A damaged or poor quality muffler can restrict this gas flow. This then creates “back pressure,” which increases fuel consumption.
It’s important to note that poor engine performance and low mileage can’t always be tied to a faulty muffler. These issues can also be caused by other systems, like your brakes or auto suspension. The most reliable way to diagnose a problem is through regular inspections by a licensed technician. If you’d like to book an inspection or have questions about your vehicle’s fuel efficiency, our knowledgeable staff would be happy to help.
When and why should I replace my exhaust system?
Corrosion, leaking pipes, and a misfiring engine can all have an impact on your exhaust system. And while wear and tear is inevitable, certain external factors – such as potholes, excessive rain, and road salt – can speed up the process.
It’s important to catch issues with your exhaust system as early as possible. A failing exhaust system can put your safety, your comfort, and the environment at risk. Components like the catalytic converter are also very expensive to repair or replace. This is why we recommend working with a trained technician to inspect your vehicle regularly and thoroughly.
Like anything that gets neglected, issues with your exhaust system will eventually display signs you can’t ignore. Here are some signs that you may need to bring your vehicle in for an inspection or repair:
- You notice a putrid smell like rotten eggs in the passenger cabin.
- You hear rattling or other loud sounds while driving.
- The check engine light is activated on your dashboard.
- You notice a sudden drop in mileage and need to refuel more often.
