The vehicle will sound louder or noticeably different if the silencer is damaged. You can work out if the muffler is damaged by inspecting it. Does it have holes or rust? If you find any rust, it may mean there is a bigger problem within the muffler.
Be careful you don’t touch the exhaust pipe while it is still hot. Let it cool down first.
The exhaust system is bound to run into some common problems over time.
You can usually tell if there is a problem with your exhaust system, as there are some clear warning signs which include:
The exhaust drags on the ground or rattles
There are louder than usual exhaust sounds
There is an unusual smell coming from the exhaust
Rust Damage
The most frequent way an exhaust is damaged or has wear and tear is due to rust, which can cause many different problems. If the rust problem is severe, it may even lead to structural damage or cause a complete exhaust failure.
In the most extreme cases, an exhaust pipe can be so damaged or corroded that it will come loose, and drag on the road as you drive.
If you find yourself in this situation, you should take your vehicle to the closest auto mechanic ASAP. If your vehicle is not safe to drive, then call the RACQ for roadside assistance.
Be careful not to inhale any fumes from the exhaust, as these may be
Rattling
What about if you hear a rattling sound under your vehicle? This usually means that there is something which has come loose. Generally, it is a bracket, piece of the exhaust pipe, or a heat shield.
If this is the case, then you should have your exhaust system serviced ASAP. Missing brackets or loose exhaust parts can end up damaging other more expensive pieces by adding extra stress to the structure of the exhaust system.
To DIY fix this kind of damage, there is a variety of exhaust mounting kits available.
Exhaust Fact: Going on many short journeys in your vehicle can lead to accelerated exhaust erosion. After you go on a short drive, the water vapour cools. Then it turns back into a liquid. This causes a higher chance than usual of rust formation in your exhaust.
Whether you are looking for a stock exhaust system or a high performance exhaust system, hiwowsport has you covered for all your exhaust system needs. From exhaust manifolds, catalytic converters, stainless steel automotive exhaust systems, cat-back exhaust systems to cavity mufflers, we always have something for your car.
Having a healthy exhaust system provides many benefits, such as:
To maintain energy performance and fuel efficiency
helps to keep the engine noise at a minimum
Turns any dangerous chemicals from exhaust fumes into non-harmful ones.
Exhaust Manifold Common Problems
Exhaust manifolds are easily prone to damage from a few different ways.
Firstly, exposure to cycles of extreme pressure, and heat. This leads to the exhaust manifold being so worn out, that it can no longer withstand the heat. When this happens, cracks start to form on the manifold. Over time, these cracks can then turn into small holes which is enough to cause a total failure.
Secondly, the exhaust system hangers or mountings may break. This leads to the exhaust manifold experiencing extra pressure, which it has not been designed to withhold.
Oxygen Sensor Common Problems
Over time, as oxygen sensors become worn, they will give less accurate measurements.
Luckily, any modern vehicle has an alert on the dashboard to notify you anytime a sensor malfunctions.
It’s wise to replace faulty oxygen sensors as soon as you notice a problem. They are vital for fuel economy, and if not working correctly, can lead to a considerable amount of money due to extra petrol costs.
