Exhaust systems are designed to move the spent gases from the engine. Aftermarket exhaust systems maximize engine’s outflow giving more horsepowers and torque along with improved fuel economy. Custom exhaust systems are also defined by their growling tone. The factory exhaust systems are not tuned to give maximum performance for the engine, auto manufacturers spend more time at designing air vents than on exhaust pipes. Aftermarket exhaust systems reveal concealed potential of the engine. Custom exhaust systems can provide 1-2% of overall fuel economy. Brand-new exhaust system will not only give you the power increase, but will also provide loud roaring around you. When planning an upgrade of the exhaust system you need to take into consideration that emissions control equipment does not need to be removed. Choosing among all types of exhaust systems the best is a “cat-back” system, it allows to put large-diameter exhaust pipes and low-restriction performance mufflers into your exhaust system without harming the catalytic converter. With this type of system you will maintain legal limits of emissions along with receiving more torque and horsepower, less exhaust back-pressure, and a sportier sound.
Maintenance of your vehicle is a must, you need to check your exhaust system once in a while to be sure that your vehicle will run smoothly. As a rule stock exhaust systems include one pipe, though custom may have dual pipes to increase the performance of the vehicle. Aftermarket exhaust systems provide extra roaring especially if the owner aims to make his vehicle look stronger, with more muscle power. Dual performance exhausts will increase power output, because two pipes work together to burn fuel and oxygen for the car. The more combusted gas expelled, the more running power to your vehicle. If the exhaust system is maintained correctly it will serve lifelong. Though the exact time and performance of the exhaust system depends on how much you travel. Short trips may lead to the corrosion of the exhaust. If your car makes too much noise it is a sign that your exhaust system is damaged, and has holes, that will emit noxious fumes.
