Exhaust System Guides

The exhaust system is an assembly in a vehicle's engine that takes care of the burnt gas that the engine produces. It consists of exhaust pipes, through which exhaust gas flow through from one chamber to another, a header, which collects the same gas from different cylinders and directs it to the pipes, a catalytic converter, which converts the pollutant gases produced during combustion into less harmful substances, a muffler, which reduces engine noise, and a turbocharger, which increases engine power.
The exhaust system is vital to any vehicle because the life and performance of the vehicle's engine depends on it. An engine cannot function well if there is back pressure trapped in it. Trapped exhaust gas chokes an engine and stops it from doing productive work. As a result, the vehicle cannot run smoothly and silently, or in the worst cases, will not run at all.
This part of the auto framework is so important that some vehicles run on dual exhaust systems. The engines of such vehicles can give off exhaust gas more freely and are capable of more power than normal engines.
Thus, a superior auto exhaust system is necessary for any type of vehicle. The bigger the exhaust pipes of an exhaust system are, the better, because exhaust gas can take their exit more freely that way. The government in most states is not kind to motorists who run on defective exhaust systems, and so utmost care must be taken in purchasing the right exhaust system.

Exhaust System Buyer’s Guide

Summary

  • A car exhaust system is responsible for collecting the exhaust gas, converting harmful gases into water vapor and carbon dioxide, and reducing engine noise. 
  • Exhaust systems differ in types, which are influenced by the layout of components used. Regardless of type, the parts that make up the system are pretty much the same.
  • Cat-back, axle-back, and header-back are the three common configurations of an exhaust system.
  • Your exhaust system is at risk if you observe a loose exhaust pipe, noisier engine sound, and a drop in fuel efficiency.
  • OE replacement exhaust systems on the CarParts.com cost from $120 to $5,900, and are sold as an assembly, as part of a kit, or in sets of two.

 

Every vehicle with an internal combustion engine ignites an air-fuel mixture to convert heat into mechanical energy. One combustion cycle creates gases that need to be released in able for the cycle to continue. This is why gasoline or diesel-powered vehicles are fitted with an exhaust system. This system provides a passageway for the exhaust gases toward the tailpipe. The process might sound simple but the system also needs to convert toxic gases into less harmful emissions, while also suppressing engine noise. 

If you’re in the market for an exhaust system replacement, you’re in the right place. CarParts.com offers a wide range of OE replacement exhaust systems to cater to your repair needs. But before you scan the catalog, allow us to give you a brief, yet concise, introduction to car exhaust systems.

What is an exhaust system?

A car exhaust system consists of tubes that run underneath the chassis. It is responsible for collecting exhaust gases, converting thees harmful gases into water vapor and carbon dioxide, and reducing engine noise. It is made up of multiple components that are necessary to perform each task. To better understand how your exhaust system works, you must know the different parts that make it up.

Parts of an exhaust system

Exhaust systems differ in types, which are somehow influenced by the layout of components used. However, the parts that make up an exhaust system are often shared by different exhaust types. Here are the different parts of an exhaust system.

Exhaust Manifold

The exhaust manifold connects each cylinder to the main exhaust pipe. The tubular exhaust manifold is colloquially known as a header and has multiple exhaust head pipes for each cylinder.

Exhaust Joints

Slip-fit tubes that comprise your exhaust system are secured by exhaust joints. These seals also secure the hangers holding the pipe in place. There are different types of exhaust joints, which are the U-bolt, ball and socket, V-band, and flat band clamps. Most exhaust joints are not welded, meaning replacing them would be easy.

Hangers

Hangers are what hold or suspend the exhaust pipe underneath your car, from front to rear. These fasteners vary in design; some are made of rubber, while some are made of steel. However, there are exhaust hangers that are made of both steel and rubber.

Oxygen Sensor

Oxygen sensors are devices that measure the amount of oxygen in the exhaust system. They are either mounted in front or behind the catalytic converter, which is known as upstream and downstream respectively. The upstream sensors measure the amount of oxygen in the gases from the chamber, while downstream sensors measure the oxygen content of the gases exiting the catalytic converter.

Catalytic Converter

Exhaust gases carry harmful chemical compounds, such as unburned hydrocarbons and nitrogen oxides. To prevent this from being released in the atmosphere, car manufacturers install a catalytic converter along the exhaust pipe. A catalytic converter features two ceramic blocks that break the molecules of nitrogen oxide and hydrocarbons to convert them into water vapor and carbon dioxide, which are less harmful to the environment.

Muffler

The muffler is responsible for breaking the sound waves coming from the engine as a result of combustion. It does this by routing the sound waves through tubes or multiple chambers inside a metal housing. Puncturing the muffler or taking it out will result in a very loud engine roar, which might be illegal in some states.

Types of exhaust systems

Knowing the parts is not enough to understand how an exhaust system functions. Your vehicle’s exhaust system might be different than the type you have on top of your head, as there are different types according to design or layout.

Cat-Back Exhaust System

Cat-Back refers to all components of your exhaust system that come after the factory catalytic converter. A cat-back upgrade replaces your exhaust system’s intermediate pipe, muffler, and tailpipe.

Axle-Back Exhaust System

As the name implies, axle-back exhaust systems include components past the axle to the exhaust tip. Upgrading with an axle-back exhaust system replaces your muffler and tailpipe. Axle-back exhaust systems are relatively cheaper and easier to install than cat-back types.

Header-Back Exhaust System

Header-back exhaust systems replace all components from the exhaust manifold. This means you’ll be installing a new catalytic converter, intermediate pipe, muffler, and exhaust tips, which is more difficult compared to replacing with a cat-back or axle-back exhaust system.

Exhaust system configurations

Aside from the types, exhaust systems are also categorized based on the structure. Here are the most common exhaust system configurations in the market.

Single Exit Pipe

A single exit pipe has a structure with one exhaust tip. This configuration is commonly seen as the default setup on regular passenger vehicles and trucks, as it is cheaper compared to other configurations. The exhaust tip of a single exit pipe is usually found on the passenger side.

Dual Rear Exit Pipe

A dual rear exit pipe, as the name implies, has two exhaust tips on the driver and passenger side. This exhaust configuration is often used in high-performance cars and trucks. Dual rear exit pipes are more efficient in expelling exhaust gas and gives the vehicle a distinct sound with a deeper note.

Signs your exhaust system is in bad condition

Your vehicle’s exhaust system is crucial for keeping your vehicle’s emissions within the legal limit. If it begins to fail, harmful chemicals will be released into the air, damaging the environment. In addition to that, bad exhaust can cause poor fuel efficiency. If you want to avoid these, you need to be aware of the symptoms of a failing exhaust system.

Loose exhaust pipe

If you notice a loose exhaust tip, meaning it moves around when the car drives over a bump, chances are the exhaust hangers need a fix. Loose exhaust pipes can easily break after bouncing off a large bump or after getting hit by road debris. Make sure to bring your car to the mechanic if you find yourself with a hanging exhaust pipe.

Louder engine noise than usual

A louder engine sound may indicate a tear along the exhaust pipe, or a possible damaged muffler. A muffler tones down the engine noise by breaking the sound waves in a series of chambers. If the divisions separating the chambers are damaged, the muffler won’t be able to do its job properly. You may also experience more intense vibrations if your car has an exhaust problem.

Poor fuel economy

A damaged exhaust can cause an exhaust leak, which can cause your engine to run with hotter temperatures. An uncooled engine won’t perform as efficiently as it was designed to be, resulting in reduced fuel efficiency.

How much is an exhaust system?

CarParts.com has thousands of OE replacement exhaust systems in its catalog. These include different types and configurations from reputable brands that offer high-quality parts. OE replacement exhaust systems on the website cost from $120 to $5,900, and are sold as an assembly, as part of a kit, or in sets of two.

Important Facts You Need to Know About Exhaust System

Let your auto exhale the right way by making sure that its exhaust system is in top shape.
Just like our lungs, your car also needs to exhale properly. Well, can you try not exhaling? You'll see how difficult and clogged up your lungs would feel. That's because we wouldn't be able to let out waste gases that our body doesn't need. Vehicles are the same thing. So while we have our respiratory system to exhale, automobiles have an exhaust system to do just that.
Exhaust systems release the toxic fumes produced by engine during internal combustion. The exhaust process starts with the manifold, which collects exhaust gases from the engine. These gases then pass through the catalytic converter, which reduces the toxicity of these gasses. After that, the exhaust gasses then pass through a series of pipes. These pipes control the flow of the emissions, and are then released from the car through the tail pipe and the muffler. With the help of these exhaust system parts, your car's engine operates more efficiently and therefore gives better vehicle performance.
Having a good exhaust system is as vital as having healthy lungs. So even if just one part of your performance exhaust system gets damaged, replace it immediately. No matter what kind of exhaust parts you choose, performance or OEM, so long as it allows your engine to inhale and exhale properly, then it's all good.

The Automobile Basics: Exhaust System

Horsepower is not the only thing that's produced by the engine. Exhaust gases are also generated. It's vital for these gases to be removed from the system because if not, they can cause backpressure in the engine which can cause its early wear. Getting rid of these gases is the Exhaust System's work. This system is an assembly of tubes that routes the exhaust gases from the combustion chamber to the tail pipe and out in the open air. To make this possible, the system is made up of several components like the exhaust manifold, exhaust pipe, muffler, catalytic converter, and the tail pipe. The exhaust gases are received by this exhaust manifold after they're produced by the engine. Then, the exhaust pipes transport them to the tail pipe. However, before they reach the tail pipe they have to pass through the muffler and the catalytic converter where their sound gets muffled and their toxic content is reduced. Aside from simply removing the exhaust gases, the Exhaust System also helps in making the exhaust gases less poisonous when they join the atmosphere. Due to its vital roles, the exhaust must be kept in tiptop condition at all times. Regular inspection is a must for car owners to know if a part is already worn-out and in need of a replacement. Anyway, finding a replacement is not difficult because a lot of online and local stores offer high-quality Exhaust System selections.
