High Performance Exhaust Systems

View:

The engine of your Toyota can produce an enormous amount of power, but it can also produce an enormous amount of exhaust or emission byproducts. During the internal combustion process, the engine in your car generates large amount of harmful gaseous byproducts such as carbon monoxide, hydrocarbons, and nitrogen oxides which can pollute the environment and create health risks in people. However, the Toyota comes equipped with an exhaust system that reduces these emissions to an acceptable level. The automotive exhaust system is responsible for converting the gas byproducts created by the engine during combustion. A typical exhaust system is made up of tubes, pipes and other various devices that work together to reduce the toxicity of the emissions of your car's engine. And all of this begins with the cylinder head. Although it also an engine component, the cylinder head is a crucial part in the exhaust system because it connects the engine cylinders to the exhaust pipe. During engine operation, the exhaust gases come out of the cylinders and travels through the length of the exhaust pipe. An oxygen sensor located in the pipe detects the amount of oxygen contained in the exhaust gases, and the data taken from the oxygen sensor will then be transferred to the engine management computer, which will then adjust the air-to-fuel ratio in the engine according to the information taken by the sensor. This process takes only a matter of seconds, and by the time the computer has finished its calculations, the exhaust gases are just about to enter the catalytic converter. Also known as the catcon, catalytic converters has the primary job of breaking down the toxic gases from the engine emissions into safer components such as water vapor and carbon dioxide. The catalytic converter does this by using a precious metal as a catalyst to break down the exhaust gases. After the exhaust gas has been treated by the catalytic converter, it again travel through the exhaust pipe until it reaches the exhaust muffler. It is the job of the exhaust muffler to reduce the engine noise carried by the exhaust gases. The muffler does this by using a series of tubes and pipes that are specially arranged in such a way that the different frequencies of the engine noise a separated and made to collide with each other, thus effectively canceling the sound out. Car exhaust systems have been in use for decades, and over the years it has been upgraded to meet the demands of modern automobile engines. Most cars today have two catalytic converters equipped in their exhaust system, and now come in a honeycomb design that reduces emissions better. But aside from emission control, the exhaust system can also be enhanced to add a touch of style to your vehicle. Take the Toyota Exhaust Tip as an example. The final part of the exhaust system of the Toyota, the Toyota Exhaust Tip gives your car a more stylish and attractive look. There are many sizes of exhaust tips available today, and they also come in different shapes such as square, round, or oval-type exhaust tips. And what's more, changing your Toyota Exhaust Tip can also change the exhaust note of your vehicle, giving you added customization for your ride.

High Performance Exhaust Systems

- Serious horsepower and torque gains

- Distinctive, growling exhaust tone

- Improved fuel economy

Horsepower and torque

In case you skipped out on Auto Shop back in high school, I am here to give you a quick lesson on the mysterious inner-workings of your engine's cylinders. Without cylinders, your vehicle could not drive around, unless you could convince your friends to lend you their backs and push you all over town. That's because the majority of your horsepower is generated right there in your cylinders through a fairly straightforward process, called combustion.

First, the cylinder sucks a mixture of oxygen and fuel (gasoline or diesel) into its chamber, where it is then ignited by a spark plug or glow stick. These three ingredients create a controlled explosion, or combustion, which generates both energy and waste gases. That energy transforms into wheel-turning torque to propel you down the road, but the exhaust is a cloud of useless particles that would clog up your engine if left to linger in the piston chamber.

That's where the exhaust system comes into action. The spent gases are exhaled, traveling out of the engine through your exhaust manifold, and they eventually exit out the back of your vehicle. The faster the exhaust gets out of the way, the easier it is for your engine to breathe, which means more horsepower, torque and fun behind the wheel.

The problem with stock exhaust systems is that they are not optimized for the best possible flow. Auto manufacturers spend much more time thinking about the shape and placement of your air vents than they do planning your exhaust pipes. What's the result of their neglect? Your motor has to work harder during combustion, which robs you of valuable horsepower, torque and fuel economy. A performance exhaust system will harness the potential power that your engine is wasting because of its inefficient stock exhaust.

Quick-installing, bolt-on performance exhaust systems improve your power by:

- Drastically reducing restrictions in your pipes

- Increasing the puny diameter of stock pipes

- Improving engine scavenging

The Growl

With a performance exhaust system, you not only feel the power every time your foot hits the peddle, but you also hear it thundering and rolling around you. Nothing quite improves your vehicle's presence as a throaty, rumbling exhaust system. When you hear each and every piston firing in rapid succession, you truly comprehend the unbridled force lurking under your hood. Stock exhaust systems try to hold back your engine's naturally forceful tone with thick-walled exhaust manifolds and mufflers that stifle your vehicle's rich resonance, rather than enhance it.

When it comes to the sound of your vehicle, the muffler has the most impact. Of course, you can tell by its name that a muffler's job is to dampen the sounds pouring out of your tailpipes. Without a muffler, your vehicle would sound like a string of M80 firecrackers exploding in a metal trashcan. On the other hand, a stock muffler suppresses the naturally aggressive rumble of a strong engine to a spineless wimper. Take control of the tone of your vehicle with a performance exhaust system for the perfect balance of sound and suppression.

Fuel Economy

Unless you've got your own oil derrick churning out barrels of Texas Tea in your backyard, chances are you too are feeling the pinch at the pump due to the rising costs of gasoline. And while it might sound too good to be true that you can get better fuel economy along with serious performance boosts, we're not pulling your leg.

That's because the same overall improvements that lead to greater performance are improving your engine's overall efficiency. You see, when the exhaust is flowing unrestricted down wider pipes with the right amount of vacuum left behind to keep the cycle running smoothly, your cylinders empty themselves of more and more waste gases. And when there are fewer impurities in the cylinder, your mixture of gas and oxygen burns purer, giving you greater horsepower without having to have a serious lead foot. These straightforward improvements in efficiency can result in around a 1 or 2% overall increase in fuel economy, saving you big every time the fuel gauge in your vehicle starts creeping down towards "E."

I'm convinced and I hope your are as well that the exhaust system upgrade that you end up with will improve performance, looks, and maybe even set off your neighbor's car alarm!.......:)
