Dual Exhaust systems are made up of piping and one or two mufflers and tailpipes. It provides better breathing capacity by providing easier flow of materials and thus reduces pressure, increases torque and improves the performance of the vehicle. With much better breathing capacity, more exhaust gas are disposed with more space left for an extra air and fuel mixture. Each part making up the jeep's exhaust system plays a vital role in carrying out the function of the whole system. The tailpipe, muffler, catalytic converter, EGR and PCV valves, air pump, exhaust manifold, header, exhaust pipe gaskets and exhaust pipe hangers are just a few of the components included in the system.
Tailpipes or exhaust tips are the visible part of the exhaust system usually located at the rear area under the car's body. It is where the car's exhaust is disposed out into the atmosphere. Mufflers are used to muffle or tone down the noise produced by the exhaust gas due to extremely high pressure. It is made up of tubes, metal holes and plates to diffuse the impact of sound as it go out of the tail pipe. Two types of muffler design are commonly used. The first type pushes the gas into a straight perforated pipe covered with metal or fiberglass to reduce backpressure and tone down the sound. The second type has several baffled chambers to accomplish the same purpose. Catalytic converters are used to purify the harmful gases that negatively affect the environment as it goes out of the jeep's system. The pollutants produced from the imperfect combustion of air and fuel mixture are converted from harmful to harmless through a chemical reaction that occurs as the gas passes into the car's catalytic converter.
