Understanding Exhaust Systems

An exhaust system is an essential car component responsible for eliminating harmful gases and pollutants. It directs these gases away from the engine and reduces exhaust noise. The system has two main components, the exhaust manifold, and the muffler. The manifold connects the engine to the exhaust system, and the muffler is responsible for reducing noise.

The exhaust system works by burning fuel, which creates high-pressure exhaust gases. These gases are expelled through the exhaust manifold and travel through the catalytic converter, muffler, and tailpipe, where they are released into the atmosphere. Exhaust system service required means that it’s time to check for leaks or damage and replace any worn-out parts.

It’s crucial to keep your exhaust system functioning properly to ensure your car runs efficiently and doesn’t harm the environment.
