Cat-back exhaust – an elegant way to improve car performance

If you want to improve car performance there are several car after market products that help you do that. There are many options you will need to evaluate before you can make a confident choice.

Some like a cold air intake do it by improving combustion other such as some components of body kits do so by improving the aerodynamics. Some do it by reducing the car weight such as a carbon fiber hood. Some even do it by reducing component weight such as light engine pulleys.

Amongst all these products there is one product that improves engine performance in an elegant manner. That is a cat-back exhaust. Why is it elegant? Because in improving the cars performance it doesn’t stress the engine more. Rather it reduces the stress on the engine.

To understand how a cat-back exhaust improves engine performance you must understand in simple terms how an engine generates power. An engine is where fuel is mixed with air and then compressed.  Once it is compressed the mixture is ignited and the resultant energy generates the power. However along with the energy exhaust gases are also generated when the fuel air mixture is ignited. And before the next lot of fuel air mixture can be ignited these exhaust gases have to be removed. Now exhaust gases travel out of the engine through a series of components such  as a silencer and a catalytic converter onto the final exhaust pipe. The resistance they encounter in leaving the engine creates what is known as the back pressure. The lower the back pressure the faster the exhaust gases can leave the engine.

The size and design of the final exhaust pipe impacts the ease with which the exhaust gases can make the final exit. In a cat-back exhaust the pipe diameter is larger than normal. Also the bends are designed such that back pressure is minimized. By allowing exhaust gases to leave quickly a cat-back exhaust enables the next combustion cycle to take place more easily and therefore it improves the engine performance.

Vw Exhaust for a Better Car Exhaust System

A car runs through its own complex systems. And yet, each system plays a very vital role in the performance of the car. It is not just about the engine, about the electrical systems, or whatever stuff that one puts in his car. One should also bear in mind the excess that the car contributes to the environment. For short, motorists should not just focus on what they put in the car, but also with what stuff comes out of it. More importantly, note if this “stuff” could be harmful to the environment, or to other people as well. Hence, one should know what happens under the hood of the car with the VW exhaust system. Because only VW can guarantee the best car exhaust.

The VW Exhaust system ensures that converted gas will not emit any harmful reaction to the air. It is composed of the VW exhaust parts such as the exhaust, the muffler, the exhaust pipe, and the catalytic converter. An exhaust pipe is usually tubing used to guide waste exhaust gases away from a controlled combustion inside an engine or stove. With an internal combustion engine it is usually part of an exhaust system which conveys burnt gases from the engine and includes one or more exhaust pipes. The VW Exhaust system assures the driver only high quality performance that is evident in the air and sound that the car releases.

Depending on the overall system design, the exhaust gas may flow through one or more of: the turbocharger to increase engine power; a catalytic converter to reduce air pollution; or a muffler to reduce the noise. An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with carbon monoxide or other poisonous exhaust gases if they are not properly vented to the outdoors. Also, the gases from most types of machine are very hot; the pipe must be heat-resistant, and it must not pass through or near anything which can burn or can be damaged by heat.

In most production engines, the manifold is an assembly designed to collect the exhaust gas from two or more cylinders into one pipe. Manifolds are often made of cast iron in stock production cars, and may have material-saving design features such as to use the least metal, to occupy the least space necessary, or have the lowest production cost. These design restrictions often result in a design that is cost effective but that does not do the most efficient job of venting the gases from the engine. Inefficiencies generally occur due to the nature of the combustion engine and its cylinders. Since cylinders fire at different times, exhaust leaves them at different times, and pressure waves from gas emerging from one cylinder might not be completely vacated through the exhaust system when another comes. This creates a back pressure and restriction in the engine’s exhaust system that can restrict the engine’s true performance possibilities.

So to ensure that not only good things are in the car, but the stuff that comes out of it too; one should trust the name of Volkswagen. When a car gears up with the VW Exhaust system, with its premium VW exhaust parts, the only harm that one could get is the envy of other drivers.
