Better Know Your Exhaust System

Exhaust Pipe

It’s true that cars are complex machines. There are tons of wires, gears, fluids, and other components that all make it possible to keep driving. Indeed, just like the human body, cars have a number of systems working simultaneously to power your car. One of the most important systems on any car is the exhaust. The exhaust system performs two very important functions: it decreases the noise your car makes, and it carries dangerous fumes away from the engine and passengers. Understanding how your exhaust system works will give you a better starting point if anything were ever to go wrong. Let’s go over the various components of your exhaust system. Each plays a critical role. We’ll start in the engine and work our way back:

Exhaust Manifold This is where your exhaust system gets started. In fact, your car wouldn’t be able to get rid of any fumes without it. In short, the exhaust manifold acts like a vacuum for all the nasty gases your engine emits while running. This prevents fumes, which are very toxic, from seeping into the car’s cabin.

Y Pipe For cars with 6 or more cylinders, the Y pipe is the next destination in the exhaust system. The Y pipe helps regulate the flow of exhaust fumes so as not to overpower the rest of the system.

Catalytic Convertor You may have heard this term bandied about around the garage. Your catalytic convertor is extremely important, and your car is pretty much toast without one. The catalytic convertor converts poisonous carbon monoxide into carbon dioxide. It does this by passing those gases a catalyst of platinum, palladium, rhodium, and other precious metals. If your car sounds louder than usual, like a drag racer, it might be a problem with the catalytic convertor.

Resonator The resonator isn’t found on every car and isn’t totally necessary. However, if your car does have one, it means it’ll be that much quieter. In other words, the resonator helps dampen the sound of your engine and is often called the “pre-muffler.”

Exhaust Pipe A pretty basic component of any exhaust system, the exhaust pipe is the main line from the exhaust manifold all the way to the muffler. It carries all the fumes and nasty smells along the undercarriage of your car. Because of this, you’re not constantly driving in a cloud of noxious fumes.

Muffler As its name suggests, the muffler muffles the sounds coming through your exhaust system. It’s very easy to tell when you’ve got a hole in your muffler, because your car will get a lot louder!

Tail Pipe We conclude our exhaustive journey at the tail pipe. This is the portion of metal stemming out of the muffler at the rear of your car. This is where all of the fumes and and other exhaust finally leave your vehicle for good.

So there you have it, a road map to your exhaust system! This is a very basic overview of a very complex system. If you have any questions or need service on your exhaust system, make sure to schedule an/service appointment at Keffer today!
