Automotive Exhaust Systems

Automotive Exhaust Systems

The options are absolutely endless in the world of automotive aftermarket exhaust systems. These exhaust systems can range from full replacement exhausts to just mufflers. An engine needs a good breathing system and an upgraded exhaust system will provide that. Each exhaust system is different from the next. Many manufacturers across the world claim their exhaust is better than the rest based on either quality or performance gains.

The automotive cat-back exhaust system is a very popular aftermarket upgrade for car enthusiasts. Not only does an upgraded exhaust provide better air flow for the engine, but it gives the car a better look with enhanced sound. These automotive mufflers create different sounds depending on the vehicle and the exhaust itself. Each user has their own preference as well. Some may like a deep rumble, and others may like a loud screaming exhaust. With so many products, there is an option for everyone. An automotive cat-back exhaust runs from the catalytic converter to the back of the car. Aftermarket cat-back exhausts tend to use mandrel-bent pipes which allows for smoother flow of the exhaust gases. They also use bigger piping over the car's factory exhaust system. This gives the engine more air to breathe. The automotive catalytic convertor is a part that regulates emissions into the air. This part takes three harmful exhaust gases and converts them to harmless. When the catalytic converter on your vehicle is bad, the check engine light will come on needing to replace it. This will cause more pollution to enter the air. A car's exhaust setup is sometimes run without the catalytic converter for some people. This opens up even more air and increases performance. On a side not, it is also much louder. This is for the enthusiasts who aren't worried about air pollution and just want more performance from their vehicle.

Along with cat-back exhausts, header-back and turbo-back exhausts are also offered in the automotive world. These two other options are vehicle specific and are not as common at automotive cat-back exhausts. A header-back exhaust replaces the car's stock exhaust from the header to the rear of the car. A turbo-back exhaust replaces the car's stock exhaust from the factory turbo to the rear of the car. These automotive exhaust systems are either single muffler or dual muffler depending on your vehicle. Also consistent with these exhausts is adding a downpipe. A downpipe connects the vehicle's exhaust manifold to the catalytic converter. If only upgrading the car's header and cat-back exhaust, the factory downpipe would be somewhat restrictive. It wouldn't offer everything the car's header has to give. By increasing the size of the downpipe, the header would then be able to flow even easier.

There's more than just upgrading the car's factory exhaust pipes. The car's exhaust headers play an important role in the exhaust system. Automotive headers make the life of the engine easier by helping it push exhaust gases out of the engine's cylinders. The car's headers are developed to form into one pipe at the bottom which is known as the collector. Exhaust gases flow through the collector and out the exhaust pipes. The goal of adding aftermarket performance headers to your exhaust system is to reduce back pressure. Some back pressure is absolutely needed for an automotive engine to run properly, though. The goal of an aftermarket exhaust system is to relive some of the back pressure to increase the engine's horsepower.

A car's headers and exhaust pipes aren't the only parts that contribute to the flow of exhaust gases. The vehicle's intake manifold is the first step in supplying the engine with air. Upgrading to an aftermarket intake manifold will supply your engine with more air allowing for more power. A completely upgraded automotive exhaust system including headers, intake manifold and cat-back exhaust will provide the vehicle with a more free flowing system and there will be a noticeable gain in power.

When entering the aftermarket world of automotive exhaust systems, it can be overwhelming. There are many different manufacturers and many different components. Quality is a major factor in buying automotive exhaust components. These exhaust components need to withstand everything that the outside elements present including rain, snow, ice, and salt. Aftermarket exhaust components are sometimes made from steel or stainless steel depending on where it is located on the vehicle. A full stainless steel exhaust component will prevent rust on both the inside and outside of the part. This makes for a quality product. Not only do exhaust components need to withstand the outside elements, but they must carry out the process of releasing harmful gases without a hitch. This means every single weld on a certain exhaust system component must be perfect and free of any cracks where gases might escape. Companies like AEM, DC Sports and Borla offer some great exhaust systems from cat-back exhausts to exhaust headers. These products have been proven by enthusiast all across the world.

Exhaust sound can also play an important role on someone selecting an aftermarket exhaust system. Different components will create different sounds. For example, just replacing the cat-back exhaust will have a different sound then if one was to replace the cat-back exhaust and exhaust header from the same company. Being able to obtain the sound one wants from the exhaust may take some time. Many car enthusiasts will post their exhaust note online for others to hear. One thing to keep in mind is noise pollution. In some states, overly-loud automotive exhaust systems are a target for police. Silencers can also be added to the rear muffler of the automotive exhaust system to help maintain the noise. For those interested in just an upgraded automotive muffler, it does not provide much in terms of performance but may give off a different exhaust note. It will also give the car a better look over the vehicle's factory muffler.
