Your engine produces a number of chemicals as byproducts of the combustion process, some of them poisonous to humans and the environment, as well as a wave of intense sound. These waste products must be processed before being released into the air, which is the purpose of the Isuzu exhaust system. The Isuzu exhaust system consists of a chain of components, some designed to reduce air pollution and others meant to quiet the sound of the engine to reduce noise pollution emitted from the vehicle. With the ever increasing numbers of vehicles crowding today's roads and highways, the function of these Isuzu exhaust components is more important than ever to reduce their impact on our environment. The Isuzu exhaust manifold is the first component in this efficient system, collecting the hot exhaust gasses as they are emitted from the exhaust valves of the engine, along with the intense sound wave that carries the noise of engine combustion, directing these emissions away from the engine smoothly to travel through the exhaust system. The catalytic converter is the next component to perform its function, sifting out a great deal of the harmful chemicals produced by the engine from the exhaust fumes. The muffler then does its part of the job, using several sound reducing techniques to quiet the engine noise. After leaving the muffler, the exhaust emissions will travel out through the tailpipe to the outside air, the Isuzu exhaust system having reduced the amount of air and noise pollution they contain.
