Your exhaust system is effectively a series of pipes and boxes specially designed to reduce engine noise and maintain optimum fuel efficiency.

The impact a faulty exhaust system can have on the environment is not something people automatically think of. All exhausts produce 6 gases as emissions; nitrogen, carbon dioxide, water vapour, carbon monoxide, nitrogen oxide and nitrogen monoxide. The job of the exhaust, catalytic converter and its monitoring system is to maintain the correct balance of emissions, check the engine is running efficiently and move the emissions away from the vehicle occupants.

What do I need to know about exhausts?

Exhausts have four main functions: to control noise, to direct exhaust fumes away from passengers, to improve the performance of the engine and to improve fuel consumption.

Your exhaust’s life expectancy depends on how often you drive your car rather than the length of time it has been fitted.

Bear in mind that if you use your vehicle for short trips around town then your exhaust may tend to corrode in a much shorter time and distance than if you use your car predominately for long journeys.

What are the signs that my exhaust needs attention?

One of the most obvious tell-tale signs that your exhaust needs attention is if your exhaust makes a roaring noise, this would indicate that the silencer is faulty.

Other signs include:

  1. A hissing noise may indicate a crack in the exhaust manifold, exhaust pipe or a leaking gasket whilst a chugging noise could mean a blockage in the exhaust system
  2. A rattling noise under the car could mean the exhaust has become misaligned

If you hear any strange noises at all coming from your exhaust the best advice is to take your car to the nearest Tyre Pros centre so our trained technicians can carry out a free exhaust check which will help to diagnose the fault.

All Tyre Pros exhaust systems carry a 3-year unlimited mileage guarantee and a 2-year catalytic converter guarantee.
