The exhaust system’s primary function is to guide the poisonous gases produced in your engine away from you and your passengers and safely out the tailpipe.
A malfunctioning exhaust system could mean that those toxic emissions are being piped into your vehicle, where they can do serious damage to your health. Therefore, it would be best to buy a powerful VY exhaust for your vehicle.
Where It All Starts: the Exhaust Manifold
The exhaust manifold is where the waste products of combustion (exhaust fumes, excess heat, and sound waves) first enter your exhaust system. If your exhaust system is working properly, all three will be reduced so that your engine runs smoothly and you won’t be bothered by excessive noise or exhaust odors.
This high-tech sensor monitors the level of unburned oxygen in the exhaust in order to gauge your car's fuel mixture. It helps your engine perform at its best by telling the car's computer when the fuel mixture being delivered to the engine needs to be adjusted.
Emissions are at their loudest, hottest, and most toxic state when they first enter the exhaust manifold.
Where It All Goes Next: the Catalytic Converter
The next stop for the fumes from your engine is the catalytic converter, where harmful carbon monoxide, nitrous oxide, and hydrocarbons are converted into water and carbon dioxide. Since the main purpose of the catalytic converter is to reduce pollutants, your car is unlikely to pass emissions testing if it isn’t working correctly.
Catalytic converters rarely break down, except in older vehicles, but when they do they can cause serious problems. The converter is essentially a block of ceramic plating. Over time that plating can break down and crumble.
When this happens, you’ll hear a loud sound like rocks being shaken inside a metal tin. That’s a sure-fire sign that your exhaust system needs some TLC. Don’t turn up your radio to drown out the noise, if left alone those bits of ceramic could get loose and clog up your exhaust system. That’s a big ouch for your car, and for your wallet.
