Exhaust Manifold : It is connected directly to the engine and helps by eliminating the combustion gases out of the car engine. The manifold is designed to have easy curving passages to improve the exhaust flow.
Downpipe : Helps in connecting the exhaust manifold to the catalytic converter, which then leads the exhaust gases out of the turbine chamber into the exhaust system. Downpipe connects the turbo with the rest of the exhaust pipes. Replacing the factory downpipe with bigger ones can come with multiple advantages.
Catalytic Converter : The converter uses heat and metal to act as catalysts. It consists of metals like platinum, palladium and rhodium which causes the hydrocarbons and carbon monoxide to react and produce water vapor which is less harmful. It is highly significant as it reduces toxic exhaust gases which then lessen the carbon footprint in the atmosphere.
Muffler : Muffler controls noise of the engine. Mufflers are found in 2 kinds, one that regulates chambers to curtail down noises by extending their energy into the muffler, losing force and volume. The other is designed to lower down back pressure.
Resonator : It works as a mini muffler that not only eliminates the noise that comes out of the exhaust but also makes it more acceptable.
Oxygen Sensor : Modern fuel injected cars use o2 sensors (lambda sensors) to have a measure of oxygen present in the exhaust. The computer can use this information to add or subtract fuel to get the ideal mixture for maximum fuel efficiency and performance.
Exhaust Tips : The final piece of your car exhaust system that delivers a shiny finish.
