How much does it cost to replace your car exhaust
There are so many problems that can arise when it comes to your exhaust. There are also a variety of symptoms which all point to different issues. At MyCarNeedsA.com, we want to give you a rough idea of what can go wrong and the costs involved with replacing your car exhaust. After conducting some research, we’ve found that the average cost for exhaust replacement in 2019 throughout the UK is around £148.16.
It’s impossible to give a perfectly accurate estimate for a repair until a mechanic has been able to get a close look at your specific car make and model.
In order to get an idea of costs, it’s best to start by diagnosing the problem with your exhaust. Here are some warning signs to look out for:
if you’ve noticed the colour of smoke coming from your exhaust has changed, there’s a high possibility that there is an issue somewhere within your system. The colour of the smoke may give you a clue as to what the specific issue is.
- White smoke: Your car could be low on engine coolant as a result of a cracked or warped cylinder head, a cracked engine block or a head gasket failure from overheating. If engine coolant gets anywhere near the combustion chamber, the liquid will be vaporised and converted into a white gas which is then pushed out through the tailpipe.
- Black smoke: Black smoke coming from your exhaust means that your engine is burning more fuel than it should. This is often caused by a problem with your fuel injectors, air filter or fuel-pressure regulator. Alternatively, the fuel line could be clogged.
- Blue smoke: This is a result of oil that has leaked into the engine and is being burned in the system. This happens following the valve guide seals or piston rings wearing out and allowing engine oil into the combustion chamber. If engine oil is leaking into the combustion system, you need to have the issue addressed with an oil change immediately as low engine oil levels will be incredibly detrimental to your car.
If there is a leak somewhere along the piping and fumes are escaping, this could present a very serious health risk to you and your passengers. If the leak is located at a point before the catalytic converter, it will be toxic to humans. This why it is critical that you take your car to a mechanic if your car starts to fill with smoke! Look out for these exhaust issues:
- Cracked or broken exhaust: You’ll be able to see this issue when you look at your exhaust. This can be a simple but important fix.
- Roaring Noise from exhaust: Your exhaust will emit a loud roaring noise if the silencer has been corroded by acidic moisture in the system.
- Hissing Noise from exhaust: A crack or hole will have opened up on the piping if you can hear a hissing noise as the fumes escape into the atmosphere.
- Leaking Water from exhaust: If your cars head gasket is in trouble, water may leak from the part onto the exhaust and then to the ground so if you find this issue, it may cost quite a lot to repair as is accepted for head gasket repair.
- Popping or Rattling exhaust: This will come from the result of a bracket becoming loose and not being able to hold the piping in place properly.
Exhaust repairs could be as simple as welding a small crack shut, which can cost around £50 or as large as the entire catalytic converter which could cost £1,500+.
