While the exhaust system is easy to overlook, this vital component is essential for your vehicle's safety and efficiency. Understanding the basics can help you identify potential exhaust repair needs before they get worse. Learn more about your exhaust system in the guide below. 

4 FAQ About the Exhaust System

What does the exhaust system do?

An exhaust system has four main functions. The first and most important is the release of harmful combustion gases created by your engine. The exhaust system discharges gases through the exhaust manifold, reducing your risk of carbon monoxide inhalation. As the gases escape, your muffler dampens the sound, resulting in quieter engine performance. A well-maintained system allows your vehicle to breathe easier, reduce emissions, and support your fuel economy.

How do I maintain my exhaust system?

Your vehicle's exhaust system comprises many parts. If one component is faulty, it can compromise the entire system, resulting in the need for exhaust repairs. Reduce long-term damage by performing proactive maintenance, such as repairing broken parts and fixing leaks or cracks within the pipes or manifold. 

Engine issues can also arise from the emission system. If your check engine light comes on, take your car in for diagnostics. 

When possible, avoid driving over potholes. The exhaust system runs the length of your car, and pits in the road can scrape, dent, or puncture the exhaust pipes, muffler, or catalytic converter.

How can I tell when I need repairs?

Recognizing your car's typical behavior can help you identify issues when they arise. For instance, decreased engine power on acceleration may be the result of a cracked manifold. Likewise, reduced engine power can overtax your fuel economy, causing your car to burn more gas than usual. 

Unpleasant odors, such as a burning smell or the scent of fuel, in your cabin may indicate the system is not removing emissions effectively. Combustion emissions can be dangerous, so if you detect them, contact a mechanic for diagnosis and repair right away. 

What causes a muffler to rattle?

On most vehicles, mufflers line up with the exhaust pipe and minimize the noise coming from your engine. Age, corrosion, or damage from driving on rough roads can cause the brackets and hangers that support the muffler to come loose, causing it to bang, rattle, or vibrate. A loose muffler can increase stress on the entire exhaust system and cause components to fail. A loose muffler is also at risk of falling off, which can be dangerous to other drivers. If your muffler is making loud or unusual noises, have it inspected and repaired right away.
