The 6 Consequences Of A Broken Or Leaky Exhaust System



car damaged exhaust

There are very few people that are very sensitive when it comes to the wellbeing of their vehicle. Some can detect the slightest fault or symptom, whereas some need the car to be broken down totally before they can realize something is wrong.

A lot of car users pay less attention to the exhaust system; maybe because they are underneath the car.
Again, because they are underneath the car, the exhaust is much more exposed to wears and rapid corrosion if left unchecked.

We won’t be wrong to say exhaust is one of the most ignored car part because it’s not what people see every day. Most drivers don’t always get down on the floor just to inspect the exhaust on a regular basis.

The exhaust system is the respiratory system of your car.

Let of see what problems a broken or leaky exhaust can cause.

1. Fuel economy is reduced:

The function of the exhaust is to channel fumes away from the front of the car, reduce engine noise as well and maintain good fuel efficiency.
If there should be a leak or blow in the exhaust system, the pressure in the exhaust would be compromised leading to reduced fuel economy. If the leak is near the engine, it will affect the fuel economy the most.

2. Increased emission:

The catalytic converter in the exhaust system has a function of reducing the toxicity of the gas produced by the engine. When there is a blow, the toxic reduction processes might not the achieved and hence, higher emission.

The exhaust produces six different gases of which three of them (carbon monoxide, nitrogen monoxide and nitrogen oxide) are toxic.

3. May damage other car parts:

The fumes coming out of the engine are extremely hot. These fumes will gradually cool down as they make their way to the tailpipe. If the hole is near the engine where the fumes are extremely hot, it can be a problem to any other delicate car part around it when they blow hot air upon them. In extreme cases, it can cause fire.

4. The fumes can make their way into your car:

This is yet another dangerous consequence of a leaking exhaust. These gases we’ve talked about that are poisonous can make their way to your cabin which is certainly not a good thing if people are inside.
You might have experienced this in one of the numerous danfos in Lagos. I believe it wasn’t a good experience for you.

5. Extra noise:

Faulty exhaust can make your car sound louder than they should. You can take notice of this noise when your car is idling. It is more pronounced when accelerating and decelerating.

6. Reduced performance:

Leaky exhaust can reduce the performance of your car. It can make your car work harder than it should in order to produce the power needed.

in conclusion, it still remains better to deal with a broken or leaky exhaust on time in order not to cost you more than you bargained. It is not a complicated task to get the exhaust fixed except it is full replacement.
