Your Toyota 4Runner SUV has a factory-installed exhaust system in place for a reason. It removes those noxious byproducts that are produced when your engine consumes fuel, leaving cleaner gases to escape harmlessly into the air. As an added benefit, some components also help stifle the noise produced during the combustion process.
How Exhaust Systems Work
First, the pollutants pass through a catalytic converter. There, metals such as platinum, palladium, and rhodium capture the toxic molecules and separate them into nitrogen and oxygen. Oxygen molecules are allowed to pass through, while the nitrogen remains trapped. The process depletes hydrocarbons and carbon monoxide, leaving behind water vapors and carbon dioxide.
Next, the exhaust manifold collects the gases and sends them along to your exhaust pipe. At the same time, the resonator and muffler maximize airflow while restricting engine noise. Finally, the cleaned gases exit the tail pipe into the air.
