The Role of the Car Exhaust System: Performance, Emissions and Upgrades

Gasoline powered cars have a collection of pipes known as the car exhaust system. This system pumps air and fuel through the engine to power the car. When the air-fuel mixture is off, your vehicle won’t run as well. It may burn more gas or struggle to get to speed from not having enough air. The gases created by the engine using fuel and air need somewhere to go. That’s why your car has an exhaust system.

The Function of the Exhaust System

The car’s exhaust system includes four main parts that work together to expel combustion gases, muffle the sound of the car and increase engine and fuel efficiency.

1. Exhaust manifold – this part collects the gases that are created in the engine when fuel is burned.
2. Catalytic converter – the catalytic converter removes toxic substances from the exhaust gases, reducing emissions and increasing safety in the car.
3. Muffler – aka a silencer, the muffler dampens the noise of the engine and reduce emissions.
4. Tailpipes – where the exhaust gases come out of the car.

A radio installation kit may be a DIY mechanic project, but for emission maintenance, you may need specialized equipment to monitor the exhaust system.

Exhaust System Maintenance and Repairs

The exhaust system is vital to your car’s performance. Many states have regular emissions checks to make sure that your exhaust system is operating effectively for the environment. If you notice your car is losing power or vibrating, it could be a problem with the exhaust system. You may also notice louder noises coming from the car or decreased fuel efficiency when there is a problem with the exhaust. Watch for signs that there could be a problem with the exhaust system. Have your system inspected by a professional that can check for leaks, corrosion or signs of aging. The exhaust system is subject to wear and tear from high temperatures, dirt and debris and residue from gases.

Upgrading the Exhaust System

Aftermarket exhaust parts can modify your system for more power, reduced sound and improved fuel efficiency. Some modifications to the exhaust system can also increase the noise and sound from the tailpipe, which may be illegal in your community. Before performing any upgrades, make sure you know the laws in your area. An aftermarket exhaust system can increase fuel economy by increasing the airflow to the engine which allows the fuel to burn cleanly. High flow catalytic converters reduce backpressure to increase horse power. There are many modifications that can update your exhaust system for better performance on and off the road.

Newer cars are improving exhaust systems to be more eco-conscious, but if you have an older car, you may want to invest in newer aftermarket parts as part of your exhaust system to use less gas and to decrease your emissions. Find a wide range of auto parts, like a motor mount or radiator replacement, at a specialized auto parts store that features quick shipping and excellent customer service to know that the part you order will fit your car.
