Many people think that the Mazda exhaust system is basically the car’s muffler. The truth, however, is that, the system is basically made up of a series of pipes underneath the body of the car that is connected to the muffler and the catalytic converter. The main function of the exhaust system is to keep noise levels to a bearable degree to as well as to route exhaust fumes away from the passenger cabin.
The Mazda exhaust system disposes of waste gases produced by the engine by letting them pass to the rear of the car, finally departing through the muffler. These exhaust fumes are discharged into the atmosphere since such substances contain noxious pollutants, mostly carbon monoxide. Carbon monoxide impairs the ability of the blood to absorb oxygen into the lungs, leading to serious health problems. Inhaling huge amounts of this gas can thus lead to poisoning. Carbon monoxide poisoning, in turn, can inflict a series of ills on a person. Headaches, fatigue, flu-like symptoms, as well as potential heart problems, are simply a few of these ills. In addition, chest pains, irregular heart beats, and in some cases, cardiac arrest are also common results if one is subjected to high intakes of carbon monoxide. In addition, the Mazda exhaust assembly also converts pollutants into less harmful by-products, levels down the noise of the engine, as well as directs exhaust gases so they can be utilized to heat air and fuel before they are burned in the engine’s cylinders. Another function of the exhaust system also includes the production of backpressure into the engine at just the right amount so as to improve the engine’s fuel-burning efficiency and performance.
The components of the Mazda exhaust system generally include the exhaust pipes. These are designed specifically for each car model so exhaust fumes are certain to be routed properly to whichever direction they need to go. Then, there’s the exhaust manifold. This component serves like a funnel; that is, it collects exhaust gases from all cylinders. After which, it releases them by way of a single opening. While the catalytic converter is well designed to lower the resulting harmful emission products generated by the engine. The system accomplishes this feat by transmuting pollutants into water vapor and other harmful gases that are significantly less harmful. Rounding up the exhaust assembly parts is the muffler. This is basically a metal container with chambers, baffles and holes. The resonator which works with the muffler to cut back exhaust noise and the tail pipe designed to direct exhaust gases away from the vehicle, are also included. As for common system troubles, rocks, dirt, and mud contribute a great deal in the failure of the Mazda exhaust system. If one notices that the engine seems to be running on less power, or if foul odors or odd noises are coming from the muffler or any portion of the exhaust pipes, then it’s already best to have the Mazda exhaust system checked and if already beyond repair, replaced by a professional.

The internal combustion engine of your Pontiac needs gasoline and air in order to make a complete combustion. Gasoline is basically made up of 2 elements?carbon and hydrogen; while air is made up of nitrogen and oxygen. The normal combustion process of your engine would produce nitrogen, carbon dioxide, and water vapor. These 3 by-products are the most desirable products of combustion. But unfortunately, gasoline engines do not run efficiently at all times. As a result, unburned hydrocarbons, carbon monoxide and nitrogen oxides are being produced. These ?terrible trio? of automotive pollutants are harmful to your engine components. Not only that, excessive amounts of these exhaust gases can contribute to urban air pollution and respiratory and heart diseases as well. To address this need, you car has been equipped with a group of components collectively known as the Pontiac exhaust system. These car components basically convey burnt gases from your engine through the subcomponents comprising it.
There are 3 types of exhaust systems?the header back, turbo-back, and cat-back. Header back comprises those exhaust system components starting from the header outlet to the final vent. This type of exhaust system is used in cars that are not equipped with turbochargers. On the other hand, turbo-back exhaust systems are used in cars that are equipped with turbochargers. It runs from the turbo charger outlet to the final vent to open air. Lastly, cat-back exhaust systems start from the outlet of the catalytic converter and ends to the final vent to open air. No matter what type of exhaust system you may have, it will make you benefit in three ways. First, you will get serious torque gains and horsepower. Second, you will get an improved fuel economy. And finally, you will get a growling and distinctive exhaust tone. The Pontiac exhaust system comes into action after your engine generates the exhaust gases in the piston chamber. These exhaust gases are exhaled out of the engine by traveling through various pipes and hoses and eventually at the back of your vehicle. A reliable Pontiac exhaust system conveys exhaust gases as fast as possible so your engine can breathe easier.
A typical anatomy of your Pontiac exhaust system comprises the exhaust manifold, headers, head pipe, catalytic converter, muffler, and tailpipe. You can usually see the exhaust manifold and headers directly above the engine cylinders. They are the starting blocks of your exhaust flow. The head pipe connects the exhaust manifold to the mufflers. The catalytic converter, on the other hand, converts harmful emissions such as nitrogen oxides, carbon monoxides and unburned hydrocarbons into less harmful gases. The muffler looks like a catalytic converter, but they serve the function of reducing exhaust noises. Finally, the tailpipe is the last piping of your exhaust system. Depending on the type of driving, regional climate, and maintenance, your Pontiac exhaust system is projected to last for 2 to 3 years. Among the major causes of exhaust system failure is internal corrosion, which can be attributed to acid moisture from the combustion process. Do not think twice on replacing your stock exhaust system with a new one if it gets worn out to maintain an efficient engine performance.

Gibson Performance Exhaust systems are manufactured in gas and diesel applications for cars, trucks and sport utility vehicles with a limited lifetime warranty and will not effect factory warranties. With options such as aluminized or stainless steel and five different exhaust exits, there is no going wrong with Gibson?s line of performance cat-back systems. You will certainly find what you are looking for in this line with the style, torque, tone and brilliant engineering, whether your vehicle is for work or for play. The performance and durability of these parts are also quite impressive. Almost all of the parts come zinc-plated with heavy-duty stainless steel clamps and offer the maximum exhaust flow for the most efficient exhaust and have three to four- inch tailpipes.
The Gibson Side Swept Exhaust will provide a quick acceleration and the best towing power. Hill-climbing is at its easiest with a low-end horsepower gain and at the same time you?ll have a quiet in-cab, low tone. Exit is behind the rear tire near stock, and the mandrel- bent tubing keeps exhaust flow constant for maximum performance. This side-swept exhaust comes with a T-304 high polished stainless steel clamp-less slash tip and zinc plated 3/8 to
