Exhausts

There’s a lot more to your car’s exhaust than you might think. As well as getting rid of spent gases, it controls noise, boosts engine performance and improves fuel consumption.

Are you fuming?

Spotting exhaust problems early could stop you fuming.

There's a lot more to your car's exhaust than you might think. As well as getting rid of spent gases, it controls noise, boosts engine performance and improves fuel consumption.

The exhaust is a series of pipes that link the engine to the tailpipe. Exhaust gases leave the engine and go into the catalytic converter (which helps reduce exhaust emissions). A series of pipes then take the gases into the silencer where metal plates or tubes reduce the gas pressure so that they are quieter when they leave the car.

How long your exhaust lasts depends on the type of driving you do - vehicles used for short trips around town tend to corrode their exhausts in a much shorter time than cars used predominately for long journeys.

Whatever kind of driving you do, it's always a good idea to listen for changes in your exhaust noise, as its tucked away, and it's not always easy to notice problems developing unless you listen very carefully. Noises coming from your exhaust are usually a good indication that something is not as it should be - a roaring, hissing or chugging noise, a rattling or a vibration could indicate a problem.

Fortunately as exhausts are made up of so many sections, if a problem is spotted early enough, it may well be possible to change just one small part rather than the whole system - saving you time and money. Just seek some professional assistance from your local HiQ car care expert if you think there is something wrong.

Your exhaust is a series of pipes that link the engine to the tailpipe. Exhaust gases leave the engine and go into the catalytic converter (which helps reduce emissions). A series of pipes then take the gasses into the silencer, where metal plates or tubes reduce the gas pressure so that they leave the car more quietly.

How long your exhaust lasts depends on how far and how often you drive your car. Vehicles used for short trips around town tend to corrode their exhausts in a much shorter time than cars used predominately for long journeys.

What does the exhaust do?

Exhausts are complicated systems designed to reduce engine noise, redirect harmful gases, improve engine performance and increase fuel efficiency.

Does an exhaust make your car faster?

Aftermarket exhausts can improve the efficieny of gas expulsion allowing more clean air and fuel to mix increasing power output.

Can you drive with a hole in the exhaust?

Driving with a hole in your exhaust can be extremely hazardous to the both the driver and passengers with harmful fumes being redirected ineffectively. In addition, a hole in your exhaust is likely to cause major performance issues and is a common cause for a MOT failure.

How do I know if my exhaust needs replacing?

The most common signs of an exhaust issue are:

  • Increased engine noise often as the result of a leak
  • Reduced fuel efficiency
  • Increase in vibrations caused by loose fixtures
