Introduction

A noisy car exhaust may well start off as a rather minor iteration, that’s of a slight whistling sound as you drive along, however, left as is, bigger problems could occur.

That’s because, despite a lot of people thinking that a cars exhaust is a relatively simple bit of pipe work, often they are not that simple.

Instead, our cars exhausts often will have “catalytic convertors”, sometimes multiple sensors as well as a silencer. Its these sensors that are built into the exhaust system on some model cars which can trigger fault codes, in some instances the car could even go into “limb home mode” because the cars onboard computer, that’s the ECU has detected a fault with the exhaust system.

The main purpose of an exhaust is to as efficiently as possible take exhaust gases from the manifold, right to end of the car as smoothly as possible.

Yet, as you can imagine, running an engine will leave a build-up of soot residue, this is especially so in diesel cars, so this means that some exhausts, can become damaged or even clogged. If the car cant emit its exhaust gases correctly, then this can compromise the whole performance of the car.

On some cars there can be other problems, for example on the “back-box” of an exhaust, or indeed on any part, because the underneath of the car is subject to salt, and the elements, these parts can rust. This can cause holes to occur in the cars exhaust, meaning gases are not flowing through the pipe work, and instead being emitted in rust holes in the exhaust.

This again is something that will need urgent attention from a qualified mechanic.

The issues with a car’s exhausts can therefore sometimes be wide ranging, for example, ranging from a sensor not communicating correctly with the car’s onboard computer, right through to a clogged DPF which has put the car into a limb mode.

This can also occur with any brand car, however some cars may have “stainless steel” exhausts, which are made so they do typically last longer.

Therefore, a cars exhaust is something that may need to be repaired or replaced regardless of brand.

So if you own a car that has faulty exhaust, DPF or catalytic convertor, they why not give us a ring?

Let’s now quickly run through some of the common faults that can occur with a cars exhaust system.

 


Does your car sound different from normal?

As you drive down the road, you might well hear a slightly louder sound coming from your cars exhaust? This could range from a hole in the pipe or the silencer that has developed a fault. Rust may have deteriorated the exhaust to the point where exhaust gases are now escaping from a part of the exhaust rather than at the end of the back-box or silencer.

Sometimes a “fault code reader” will be needed for electrical faults, however sometimes when the car is put on our ramps, sometimes its just obvious to the mechanics eye that the exhaust is rusted, or maybe come away from the rubber clamps which sometimes hold some exhausts in place.


DPF Problems

On your cars dashboard there may well be an error code being displayed which relates to your cars DPF?

This means that the DPF may need replacing or cleaning, there may well be other fault codes, therefore the car will need bringing to our garage, so that we can put your car on our diagnostics machine, so we can read the cars fault code.


Rust

As the cars exhaust is on the underneath of the car, and leads directly to the engine, it is subject to huge amounts of heat, plus also the weather conditions under the car can cause the metal to rust. For example, wet roads, and also salt when it is spread over the roads during the winter, all can accelerate rust setting into the cars exhaust.

This is why a car’s back-box can sometimes rust sometimes to the point that holes occur in the steel, which can make some cars exhaust to sound abnormal.

This should not be ignored, our garage will be able to help you, we can also offer different types of exhausts.

For example, you may wish to opt for a longer life exhaust, one that is made of stainless steel for example?


Exhaust check

You may want one of our mechanics to check over your cars exhaust, even if the sound difference with the cars exhaust is only slight right now, this doesn’t mean that the problem won’t get worse.

What can occur, is if the exhaust is rattling, the whole exhaust may fall off, any problems with a cars exhaust should be seen by a qualified mechanic.

If your car is undrivable or our mechanics have discussed with you over the phone, that the car shouldn’t be driven, then we can collect the car from you using our recovery truck.


Manifold issues

Our garage can also fix and repair manifold issues that may persist with your cars exhaust.
