Exhausts and diesel particulate filter (DPF)

There’s a lot more to your car’s exhaust than just the pipe poking out of its rear end. As well as directing away spent gases it controls noise, boosts engine performance and improves fuel consumption. But because its tucked away on the underside it’s not always easy to see problems developing – unless you listen carefully.

If you hear odd noises coming from your exhaust – a roaring, hissing or chugging noise for instance, or a rattling or metallic vibration – the best thing to do is pop it in to see us as soon as you can. Our trained exhaust specialists will be able to diagnose the fault and help you decide your best course of action.

If the fault’s been discovered early enough, it may well be possible to change just one small part rather than the whole system – saving you time and money. Well, we figure, if we save you money in the short term, you’ll keep coming back to us in the long term.

Our exhaustive(ish) guide to exhausts Your exhaust is simply a series of pipes that links the engine through lots of other important bits to the tailpipe. Exhaust gases leave the engine and go into the catalytic converter (which helps reduce emissions). A series of further pipes take them from here into the silencer, where metal plates or tubes with holes bored into them reduce the gas pressure so that they leave the car, via the tailpipe, more quietly (which stops you annoying the neighbours).

How long your exhaust lasts for depends on how far and how often you drive your car rather than the length of time it has been fitted. Vehicles used for short trips around town tend to corrode their exhausts in a much shorter time and distance than cars used predominately for long journeys. Whatever kind of driving you do, it’s always a good idea to keep an ear open for changes in your exhaust noise. If you do detect a change, just drop in to see us for a free exhaust check.
