Mufflers are used to reduce the amount of noise emitted by vehicular and non-vehicular machines. It was invented along side the firearm suppressor (also known as the silencer) by the American mechanical engineer Hiram Percy Maxim. Typically installed along the end of the exhaust pipe, Mufflers are part of the elaborate exhaust system of the vehicle engine. The device accomplishes the reduced noise because its intelligent chamber design. Opposite sound waves collide and cancel each other out as they pass the specifically designed resonating chamber of the muffler. "Inside the engine, pulses are created when an exhaust valve opens and a burst of high-pressure gas suddenly enters the exhaust system. Collision happens when the molecules of this gas meet the lower-pressure molecules in the pipe. Leaving an area of low pressure behind the sound wave makes it may down the exhaust pipe then to the muffler's tube. The resonator, a chamber that contains a specific volume of air and has a specific length, calculates and produces a wave that cancels out a certain frequency of sound. The wave travels through the chamber hits the back wall of the muffler and bounces back out of the hole. The length of the resonator chamber is calculated so that this wave leaves the resonator chamber just after the next wave reflects off the outside of the chamber. The high-pressure part of the wave will line up with the low-pressure part and then the two waves will cancel each other out reducing the noise level." Noise is not the only problem that vehicular engines emit. Harmful chemicals such as Hydrocarbon, Nitrogen Oxide, Carbon Monoxide and Carbon Dioxide are released to the air through tailpipe emissions. Environmentalists have tackled this issue and regulated car manufacturers to add devices that will limit or reduce this kind of atrocious emissions. Car enthusiasts has always given the engine exhaust system extreme importance as it significantly adds up to the overall performance of the automobile. Horsepower is maximized by the efficient detonation of fuel and unrestricted exhaust flow while Torque is gained through good circulation of air. Exhaust systems may be elaborate and complicated but manufacturers and consumers take time to fully understand its mechanisms. Gibson Performance Exhaust is a company that offers extensive products for exhaust system modification. Located in an ultra-modern facility in Corona, California, this family operated business has been servicing and supplying exhaust system excellence for more than 14 years now. Manufacturing products for sedans and muscle cars, they currently produce exhaust devices for trucks, SUVs and even motorhomes. Company president Ron Gibson, runs the production of Gibson performance products. He sees to it that the overall performance of a vehicle is enhanced as they continue to engineer mufflers and headers that fit the meticulous specifics of car owners. Their goal is to deliver more performance to the dollar than any other system. While keeping good business, Gibson contributes to the battle against pollution by manufacturing products and materials that pass the environment-efficient standards.
