How to spot a faulty exhaust

How to spot a faulty exhaust 26th August 2014

A working exhaust is vital, not only for the sake of keeping the environment clean but also for the safety of the driver and their passengers.

Thanks to this piece of equipment, toxic fumes produced by your car get converted into safer gases. Without this, fumes such as carbon monoxide could get into the cabin of your vehicle and others could get into the outside world.

For this reason, it is important to makes sure you exhaust is working properly and know the signs that there may be a problem with it.

Among the things you should consider is the kind of noises your exhaust makes as this is a good indicator if something is amiss.

One of the areas most likely to break first is the silencer as it is the most susceptible to acidic corrosion due to the fact that it is the part furthest from the engine and doesn't tend to get as warm. A sign that this is broken is if your exhaust makes a roaring noise.

Should you hear hissing noises, this suggests that there may be a crack in the exhaust manifold, exhaust pipe or your gasket might be leaking. Chugging sounds suggest that there is a blockage in your exhaust system, while rattling under the car suggests that it has become misaligned.

Keep an ear out for what sounds like vibrating metal too, as this may mean that something is touching your exhaust pipe that shouldn't be, or one of your brackets or mountings has become loose. If any of these brackets are broken or missing then this could result in your exhaust failing.

There may also be visual signs that your exhaust is in trouble. For example, if you see any rust on the system then this should be a warning sign.

If these things occur then it is important to have an expert technician check over the condition of your exhaust. Visit your nearest ATS Euromaster centre to get your exhaust checked, then repaired or replaced if need be.
