What does an exhaust silencer do?
A car’s exhaust system is made up of several parts that channel gases from the engine’s cylinders back into the atmosphere.
The exhaust silencer is the final section, and its job is to reduce the amount of noise created by the engine gases being forced through the exhaust pipe.
How often should an exhaust silencer need replacing?
Your exhaust silencer’s lifespan is dependent on a range of outside factors—the main ones being the weather and driving conditions. Modern exhausts made from chrome or stainless steel are designed to last for the life of the car, whereas a high-quality non-stainless steel exhaust should last for around 5 years.
The law, vehicle regulations and your MOT
A hole in your exhaust will only fail an MOT if it is responsible for a major leak or it causes the car to fail its emissions test.
What causes an exhaust silencer to stop working correctly?
Because of their location, being mounted underneath the car, **exhaust pipes **are highly prone to damage, corrosion and wear. The weather plays a significant part in the corrosion and deterioration of the different exhaust pipe sections; rust being a major player in the appearance of holes throughout the system.
Damage to exhausts can be caused by raised road elements or extrusions from the road, such as curbs or speed bumps. Damage can also occur by driving too fast over the brow of a hill or through a dip where the suspension might bottom out and cause contact between the underside of the vehicle and the road surface.
Symptoms of a malfunctioning exhaust silencer
A noisy exhaust
If your exhaust makes more noise or is louder than normal, your exhaust silencer is probably damaged or improperly attached. A common sound of ‘blowing out’ is where holes have developed in the silencer.
There are holes in the exhaust
If you can see holes developing in your exhaust, through damage or deterioration, it’s time to get a new exhaust silencer.
Excessive vibration and lack of performance
A damaged exhaust pipe can affect your vehicle’s performance, and in some circumstances develop a vibration that wouldn’t occur under normal operation.
Failure of an emissions test
The exhaust is responsible for vehicle emissions, so if you fail a test, on inspection or at MOT, then you need to replace the malfunctioning component immediately.
DS is the premium automobile marque of the Groupe PSA.
First announced in 2009 by Citroën as its premium sub-brand; it was suggested to be an abbreviation of different spirit or distinctive series. However, in French, the name is considered a play on words, as the translation of déesse becomes goddess in English.
How popular is DS in the United Kingdom?
As a newcomer to the UK market in its own right, there were around 35k DS cars on the roads in the UK by the end of 2018. Whether those figures will continue to rise at the same rate shown since their introduction in 2015, only time will tell.
Looking to provide a standalone marque to initially compete with brands such as Volkswagen and Audi, PSA decided that neither Citroën nor Peugeot would be able to carry the brand strength that would be able to make a serious threat in the market with an elevated price-point at the level of quality and luxury they set out to achieve.
DS: Establishing a new range of upmarket models
To compete with the likes of Audi, BMW and Mercedes-Benz, DS introduced a range of hatchbacks, saloons and SUVs but it’s undoubtedly their supermini city car that is proving the most popular.
The DS3, sold as a 3-door hatchback or a convertible, is available in countless customisation options and also as the subcompact luxury crossover SUV DS3 Crossback. The DS3 was voted Car of the Year by Top Gear Magazine, and first place supermini four times in a row in the JD Power Satisfaction UK Survey.
DS: Don’t be fooled into thinking they’re just a one trick pony
At the other end of the range you’ll find the DS7 Crossback. Here’s a large SUV designed to compete directly with the Audi Q5, the BMW X3 and the Mercedes-Benz GLC; that’s quite a jump for a car that’s built by Citroën.
The models that you’ll find between the DS3 and the DS7 are created with the same style for the market in mind. The DS4, a mixture of hatchback and SUV, and the DS5, a bigger hatchback priced and pitched against the Audi A4, the BMW 3 Series and the Mercedes C-Class saloons.
DS’s reliability and reputation
DS didn’t feature in the 30 car brands of the What Car? Reliability Survey in 2018, however, Citroën came in at 25th place so it stands to reason that their premium vehicles should score higher. Not necessarily so. Jaguar, Mercedes-Benz and Land Rover were propping up the wrong end of the survey, and given that the most reliable brands are all Asian manufacturers (with Suzuki, Lexus, Toyota, Kia and Mitsubishi taking the top spots) perhaps it’s simply a case of the rest of the world are having to play catch-up?
