Besides keeping your vehicle quiet, exhausts are an often overlooked safety feature.
Taking away the harmful gasses and in the majority of cases with modern catalysts converting them into nothing more harmful than water, your exhaust keeps any harmful gasses out of the passenger compartment of your car and takes them safely away, keeping you safe.
Your vehicle’s exhaust system is comprised mainly of a series of pipes. Most people know that an exhaust system removes the harmful gases produced in your engine; however, exhaust systems do a lot more! Your vehicle’s exhaust system has four main functions: control noise, carry away gases, improve engine performance and improve fuel consumption.
Exhaust gases are collected by the exhaust manifold and eventually routed out of the vehicle. The exhaust manifold acts as a funnel, catching gases from all cylinders and releasing them through a single pipe.
The quicker exhaust gasses leave your vehicle, the better fuel economy you’ll see due to the fact that your engine is free to take in more, fresh oxygen. Modern exhaust systems come with an oxygen sensor that measures how much oxygen is present in the exhaust. From there, more or less fuel can be added to maximize fuel economy and efficiency.
- The exhaust system takes away harmful gasses from your engine
- A leaking exhaust presents a safety and health issue for you and your passengers
- The condition of your exhaust can affect the performance and fuel economy of your car
- Faulty exhausts are a major reason for MOT failure
