The Importance Of Car Exhausts
Car exhaust systems are important more important than what most people believe. I mean cmon think of it this way what would happen to any system that is clogged with waste and dirt? So a faulty exhaust is a disaster in the making. It will eat away into the health of your car and in the end it might even make you and your copassengers sick. Not to mention the amount of dirt and pollution it will spew into the air. For excellent output optimum engine performance and complete riding pleasure it is important to take care of car exhausts.
Contrary to what most people believe car exhausts are not just the pipes that protrude from the rear. The exhaust system consists of engine parts through which waste gases are produced. Then there are the group of pipes that act as a bridge between the silencer and the engine. The silencer is an important part of car exhausts. It contains a number of holes which help to reduce the pressure of exhaust gases rushing out through the pipes. The silencer true to its name reduces noise levels because it contains reflectors that deflect the sound of the engine. Lastly the tailpipe stretches out from the back fender of the car. These exhaust pipes perform an important function since they guide fumes to their proper outlet behind the car.
As you can see a cars exhaust system has a number of functions to perform. It increases the productivity and fuel efficiency of the car. Thereby it enhances the engines performance. The exhaust system also reduces noise levels within the car and it guides toxic exhaust fumes through their proper channel. Tuning your exhaust can maximize productivity and speed. So selecting the correct combination of resonators pipes headers and mufflers can make your journey smooth as silk.
How to choose car exhausts:
Are bigger pipes better? In a word no. Big pipes defeat good speed. But if the pipes are too small flow will be constricted resulting in loss of power. However between the two evils having pipes that are a little small is better than pipes that are too large particularly when the car is driven in cities.
If your car mufflers are inappropriate or improperly installed you will lose almost all the advantages of a good exhaust system. In this regard note that the size of your muffler does not impact performance much. Select mufflers based on their flow not size.
Car exhausts generally have a long life period. However the exact time and performance of your car exhaust depends on how much you travel and how well you maintain your exhaust. Short trips can lead to the corrosion of the exhaust.
You will know that your exhaust system has failed when your car starts making too much noise or when your car fails the MOT test. That is because when the exhaust system has holes it will emit noxious fumes.

The History Of The Porsche
Ferdinand Porsche played an important role in the development of airplanes and racing cars and the construction of tanks for the Wehrmacht. He is an automobile engineer with more than a thousand patents to his name. He was appointed chief engineer at MercedesBenz in Stuttgart in the 1920s. Later on he set up his own engineering workshop and designed among others the Volkswagen. At the plant where Volkswagen was made Wolfsburg he was chief of operations and at the end of the war he was interned by the Allies.
He was released a few years later and started building his first car with his son Ferry Porsche. The car was named the Porsche 356 and it was a sports car and a reminiscent of the Volkswagen. It had the same fourcylinder boxer engine that was rearmounted just like the VW. It was far from being a powerful sports car developing only 40 bhp and a maximum speed of 87 mph 140 km/h. First produced as a convertible and later as a hard top it distinguished by the very elegant and innovative body. It was developed in the workshop of Erwin Komenda a master of restrained streamlining who had been in charge of sheet metal and design techniques at Porsche since the VW Beetle. The new style of closed coupe was designed by Komenda and it soon became the embodiment of the sports car thanks to its fastback.
This tradition was continued by Komenda and Ferdinand “Butzi” Porsche the founder’s grandson with the 911.
The 911 became easily recognizable: it had attractive sloping bonnet and what later became characteristic “frog eye” headlights curves running from the top edge of the windscreen to the rear bumper and a straight waistline. From a functional and technical point of view it was more like BMW 1500 although it retained the stylistic features of the original Porsche. The new 911 will become the foundation stone of Porsche’s identity even though the design was not always appreciated. During the 1970s and 1980s the designers attempts to distance Porsche from its legendary design brought the company to the edge of disaster. The more modern 924 model “a people’s Porsche” developed with Volkswagen as well as the 928 were far from fulfilling the expectations.
In the 1990s the company realized that what for over twenty years was perceived as a straitjacket it was in fact a market advantage. During the 1990s Porsche became highly profitable since they now knew that the typical Porsche features were timeless. Nearly forty people now worked in the design department on further developments of the longrunning 911. These developments included the 911 GTI a powerful combination of sports and racing car put forward by the inhouse designer Anthony R. Hatter. In 1999 chief designer proudly presented the new Boxster which enabled Porshe to establish a second independent range of models.
