The exhaust system is one of the largest components in your vehicle stretching from the engine to the tail of your vehicle – although the pipe is the only part that you can usually see!
The exhaust has an important function in your vehicle as it reduces harmful engine fumes and directs them away from the car. It also works to reduce noise pollution and fuel consumption.
If there is a problem with your exhaust it is usually quite easy to identify as it will start making unusual noises or show visual signs of rusting or corrosion.
Increased fuel consumption is a sign that you have a problem with your exhaust system. This might be due to a leak in the system so your engine is forced to work harder to maintain its performance.
Hissing noises also indicate that there may be a leak or hole in one of your exhaust components as this noise could be caused by air escaping.
Loud roaring noises is one of the most common signs that there is a problem with your exhaust. This could indicate corrosion or a problem with the silencer.
Persistent rattling noises which sounds like metal hitting metal could mean that there is a problem with your catalytic convertor, unfortunately the most expensive part of the exhaust.
Unusual emissions which could be white, blue or black in colour could indicate either a problem with your exhaust system or engine.
Even if you have not noticed any of the signs listed above, you can still make some simple checks regularly at home to make sure that your exhaust stays in good health.
Check for leaks – look underneath your vehicle to ensure that there are no pools of fluid which would indicate that you have a leak in the exhaust system.
Check for corrosion – You can visually inspect the part of your exhaust that you can see for signs of rust and corrosion. You should pay attention to seals and joins and get your exhaust checked by a specialist if you see any cracks or holes.
