How to Diagnose Exhaust Problems in 4 Simple Ways
                     How to diagnose 
exhaust problems in 
4 simple ways
Introduction
The exhaust is considered a vital part of a car. It doesn’t just diminish the noise 
of the engine; but it also ensures that the generated engine fumes are routed 
away from the passenger cabin. Therefore, it’s extremely important to ensure 
that the exhaust system is maintained in good working condition. Let’s take a 
look at a few simple ways for you to be able to diagnose exhaust system 
problems.
An abnormally loud 
exhaust 
One of the most obvious symptoms of a failing exhaust is an abnormally loud 
exhaust system. If any of the exhaust system components corrode or crack, 
this can cause an exhaust leak resulting in an abnormally loud exhaust system. 
With increased acceleration, the sound gets more pronounced. This can lead 
to exhaust gases entering the cabin of the vehicle.
A raw gasoline smell 
from the exhaust
Noticeable exhaust smells are a common symptom of an exhaust 
system failure. If any of the exhaust components are damaged, then 
exhaust fumes can enter the cabin of the vehicle. Raw gasoline smells 
inside the vehicle are a common indicator of an exhaust system failure.
Rattling noise due 
to exhaust failure
Rattling of exhaust pipes can be a serious problem. If any of the exhaust 
system components mechanically fail, they can be a hazard to other road 
users. The onset of mechanical failure can be detected by rattling noises from 
the underside of your vehicle. Mechanical vibration can subsequently spread 
to other noticeable locations including the number plates of your car.
Decreased fuel 
efficiency, power 
and acceleration
Engine performance will suffer as a result of exhaust system failures. 
Exhaust system failures result in a reduction in fuel efficiency, reduced 
levels of acceleration and a reduction in engine power.
A healthy exhaust 
system has several 
benefits such as:
• Maintaining engine performance and fuel efficiency.
• Minimizing vehicle noise levels.
• Removing hazardous products from exhaust gases.
A healthy exhaust 
system has several 
benefits such as:
• Ensuring exhaust gases do not enter the cabin of the vehicle.
• Is safe and does not present a hazard to other road users.
So, you will benefit in many ways if you take the time to maintain your 
car exhaust system
