Frequently Asked Questions:
Your exhaust system reduces noise, directs dangerous gases away from occupants, reduces fuel consumption and improves engine performance.
The exhaust system is a ‘wear part’, which means it’s designed to wear out and be replaced as this keeps you safer in the long run. Corrosion is a common problem, often around the silencer, or you may have misaligned piping.
It depends. Minor parts like brackets can be replaced for a few pounds, but an entire replacement can cost between £150 and £250 (parts and labour)
Yes. Driving would be noisier, less efficient and more dangerous without one. The exhaust exerts back pressure on the existing gases, which helps to propel the vehicle forwards.
Not always, as your exhaust system comes in sections which can be changed out individually. Some exhaust components are cheap and can be changed quickly.

More about the exhaust
The main purpose of the exhaust is to direct dangerous gases from the inside of the car. It’s made from several components, although the only one we see on a day-to-day basis is the tailpipe.
Exhaust gases are moved from the engine to the tailpipe, usually via a catalytic converter and a muffler (to reduce sound).
These components have their separate functions and they’re connected by piping that runs along the underside of the car. Each section must be airtight in order to work properly.
Different components cost different amounts of money to repair or replace, which is why it’s important to get the problem diagnosed and fixed by reliable and fairly-priced mechanics. AutoAdvisor can find your best local mechanics and garages through its UK-wide network.
Can an exhaust leak be dangerous?
Yes. Some gases, such as carbon monoxide (CO) and various hydrocarbons leak into the car, they can poison the occupants. They’re also very hot when they leave the engine, so it’s vital that they are diverted from drivers and passengers.
In addition to this, if your diesel particulate filter (DPF) is blocked or faulty, soot and other particulate pollutants can escape into the atmosphere.
The signs that your exhaust needs attention
If your engine is suddenly roaring or much louder, the silencer component may be damaged. This is usually down to corrosion.
If there’s a hole or a crack somewhere, you might be able to hear a hissing or gurgling sound. Chugging sounds could indicate a blockage, which is dangerous.
Any popping or rattling noises could indicate misalignment or a loose clamp or bracket. This needs attention before the loose part damages the parts around it.
The entire exhaust has become loose!
Your exhaust system is held in place by hangars and brackets and it’s important that these are intact or the system could be damaged or even fall away from your car.
The exhaust is rusty
Rust is a common problem, but it doesn’t always mean immediate replacement. If the metal underneath the rust patches is still intact, it’s good for a while yet but do point it out at your next service.
The exhaust is smoking
Black smoke means your engine is burning more fuel than it should. This can be due to the air filter, the fuel injectors or the fuel pressure. The fuel line may be blocked. You’re literally burning money!
Blue smoke is a sign that oil has leaked into the engine and is being burned. This is usually down to a failed valve seal or piston ring. You’ll need to have the failed part replaced and an oil change to replace your levels.
White smoke means that engine coolant has leaked into the combustion chambers and is being vapourised.
Your catalytic converter
The ‘cat’ is the component which converts dangerous fumes into safer gases that can be released into the air. It can be expensive to repair or replace. Small rust patches and holes can be fixed by a skilled mechanic, but bigger faults may mean you need a replacement.
The exhaust manifold
This is the piping that moves the fumes from the ‘cat’ to the tailpipe. It can often become loose and rattle, or become damaged and leak fumes. Small repairs aren’t expensive, but replacements can be costly depending on your make and model.
The lambda sensor
This is an oxygen sensor that monitors the levels of oxygen in the exhaust – too much can cause an explosion in the engine. It’s a cheap and easy job to replace this sensor.
Finding a good deal on exhaust repairs
