The Infiniti exhaust system is quite important to the smooth and efficient operation of your engine, carrying away the waste products of engine combustion. The engine produces a number of byproducts as it goes through the combustion process. Among these is an intense sound wave that carries the loud noise created by combustion, and a number of chemicals that are harmful both the environment and humans. If these were allowed to pass freely into the air, the levels of pollution emitted would be unacceptable, poisoning the environment with high levels of noise and air pollution. The Infiniti exhaust components process a great deal of both of these types of pollution out of the exhaust emissions before they leave the vehicle into the environment, a task that becomes more important each day as the number of vehicles on the crowded roadways steadily increases. Much of the chemical content of the vehicle exhaust fumes is removed as it is directed through the catalytic converter by the Infiniti exhaust process, burned or trapped inside this component to reduce the amount allowed to pass through to pollute the air we breathe. The muffler reduces the noise of combustion as the exhaust fumes pass through it, using several sound reducing techniques to break up and reduce the pressure of the intense sound wave that travels through the Infiniti exhaust system.
