Your vehicles exhaust system works hard to remove the toxic fumes and spent gasses from the engine in a safe, controlled manner. Without an exhaust system, your engine would produce incredibly loud, poisonous gasses as it operated. Exhaust repair is an important aspect of vehicle ownership, as it makes sure your vehicle is compliant with emissions standards and is safe to operate.

Exhaust Repair – The Basics

A vehicles exhaust system can be composed of 3 parts: The manifold, catalytic converter, and the muffler and resonator. These parts flow in order from the exhaust manifold located on your engine. As the exhaust flows out of your engine, it passes through the first part in the system, the catalytic converter:

By combining all of the gases into one pipe, filtering for pollutants and sound is much easier. The manifold connects directly to the cylinder heads on your engine, and can be stainless steel or ceramic coated for higher performance vehicles.

Catalytic Converter: The catalytic converter does exactly as its name implies. If we think back to high school science class, we know that a catalyst is something that speeds up or permits a chemical reaction. That’s exactly what a catalytic converter does. It takes the harmful gasses leaving your engine, and by moving the gases through a filter of reactive metals, converts them into safe(r) gasses. Without a catalytic converter, your car would not pass emissions tests. After the catalytic converter, the next step in the exhaust system is the muffler.

Muffler And Resonator: The catalytic converter cleans the gases in your engine, but the noise coming from thousands of tiny explosions in your engine is still deafening. This is where the muffler and resonator step in. A muffler is sometimes built to include sections of a resonator. The primary function of these parts are to dampen any engine noise. Gases and sounds are fed into the muffler, where they bounce off the surface within. The inside of a muffler is designed to create frequencies that cancel the sound of an engine out. as the gasses pass through the interior of the muffler, they lose some of their vibrations (vibrations = sound) and eventually leave the tail pipe, clean and quiet.

When Is It Time For Service?

Due to handling all the toxic emissions coming from your vehicle, your vehicles exhaust system can become easily contaminated or clogged. When driving, jerky or under performing engines can be a sign of a clogged catalytic converter. A muffler will get louder as it fails, meaning if you can hear your exhaust from inside your car, it might be time to book service. Any backfiring or other loud sounds can likely be blamed on a fault in your vehicles exhaust system, so be sure to get to service if you suspect any issues.
