All Exhausts/Catalytic Converter Stuff

All Exhausts/Catalytic Converter Stuff

Of course,the good old car exhaust is undoubtedly a distress purchase. Significantly, it can also be an expensive purchase. However most small to medium cars are reasonably priced and affordable.

Undoubtedly, your car exhaust is one of the most unnoticed parts of your car. Of course, unless you are a real car enthusiast. So, a lot of car enthusiasts actually replace their original car exhaust. Naturally, to better looking twin sports tail pipes.

The catalytic converter is one of the most important devices which make up the vehicle system. It was designed and implemented to solve emissions problems and make a growing number of cars more friendly to the environment. But a cat performs its functions properly only when the device is clean inside. The worse the quality of fuel you use, the sooner shallow holes of the honeycomb inner structure of the converter get clogged. When this happens, the airflow is restricted and metal parts can crack under the strain. In the worst case some engine problems occur.

That is why it is required to keep the cat unclogged. This is useful and pragmatic, since it is much cheaper to maintain the device rather than buy another one prematurely. But before contacting an automobile repair shop, you should get to know how the procedure is conducted.

How Emission Problems Can Be Solved

A comprehensive vehicle inspection consists of the following steps:

  • Obtaining the vehicle history and to answer the questions concerning fuel consumption, whether the engine is hard to start, the cat has been repaired or replaced, etc.
  • Correcting codes of the engine. You should know that typically codes from P0420 to P0424 and from P0430 to P0434 in order indicate some catalyst problems.
  • Identifying and fixing exhaust system leaks.
  • Checking cat temperature, back pressure, O2 sensor, and internal cooling system.
  • Fuel system inspection.
  • Measuring emissions with the help of a gas analyzer.
  • Running a cylinder balance test.
  • Examining the mechanical condition of the parts and devices.

If you have noticed some exhaust system troubles, the vehicle doesn’t need to undergo a full technical inspection. Contact a repair shop for just a catalyst testing.

In case the inspection has revealed a crucial catalyst problem due to which the device should be replaced, we suggest you look for a new one on the website https://autocatalystmarket.com/us/en. This is the biggest catalyst market where you can select a catalytic converter for any car brand and model. The range comprises over 24,000 items! The company has been working in the market of catalytic converters since 2005. Each device on the website has real pictures and a detailed technical description for you to facilitate the selection process.

How Much Does Catalyst Inspection Cost

The price depends on such factors as the car brand and model, current condition of the device, the amount of solid fuel residue in the grid holes, etc. In general, a cat repair costs between $900 and $2500. If you fill your vehicle with the fuel of good quality and keep the engine maintained, you need to have the converter repaired not less than every 100,000 km kilometres driven.

Exhausts Changed-to meet new European Union Emission Laws

Exhausts Changed

Exhausts systems also cost much more than 10 years ago

I can honestly say that I have lived during the most radical changes ever made to cars, due to the new rules about “global warming” and emissions from cars. Back in time when we had Vauxhall Vivas Cavaliers, Chrysler Horizons old type Minis and Ford Cortinas life in the garage was much easier and certainly more stable.

The exhaust systems on those cars would stay the same year after year. So much so that we could order systems in the hundreds at a time and kept a large stock, that we would always sell. In fact we could order exhausts systems by the container load and they would all be sold, (happy days).

Then the computer came along and car manufacturers could very quickly change car models, they became very flexible changing parts on different models at will.

This included systems. We were finding that Exhausts.  Like other parts would be left on the shelf unsold. Hence,we were becoming very reluctant at keeping exhausts on the shelves. Without, getting stuck with them.Consequently, at this time exhaust wholesalers began to spring up.As a result, and in a short period of time. We decided not to keep an exhaust stock at all. So, and leave it to the wholesalers.In fact. The last stock that we kept in was from Bosal Exhausts. Probably, (the best Exhausts in the World) and that was in the late nineties.

Exhausts Changed

The next thing to affect Exhausts were Vehicle Emissions controls. These were introduced by the British Government. Thus, requiring that cars had to be fitted with “Catalytic Converters.” These cats as we know them. Therefore, are fitted between the car’s engine onto the exhaust pipe system. The gas from the engine is filtered through the cat. Into a very fine filter system. Made from ceramics to withstand the high temperature. The cat has also some precious metals to help filter out the particulates. (this is why the cats are so expensive).

Some car models have a direct fitting cat to the engine. Thus, the engine sends out waste gasses. That are filtered by the cat. As a result, then the cleaner gases pass through the rest of the system. The Exhausts Changed boxes contain a fiberglass type material. Naturally,  that has an extra filter effect but will also muffle the sound that the gases make when leaving the engine. We all know how noisy a car is when the exhaust breaks.

Exhausts systems are better made these days

Some cars have two or even three boxes depending on the size of the engine and car. Here in the UK we do not change the exhaust until it actually breaks, and the we have it replaced and in my opinion this is the best thing to do. Even the worst looking rusty old Car Exhausts  can last for years and it is no use changing your exhaust just because it looks rusty and old, replace it when it breaks, unless it fails the MOT test. The main part to fail on the test will be the cat, if it fails the test the cat will need replacing.

To summarise Cheap Exhaust systems are far better made these and certainly last much longer, cats are also well made and will only fail if the ceramic cone gets damaged or if you go through flooded water, this usually affects the engine management system and your engine light could be illuminated on your dash, triggered off by your cars computer and a replacement will be needed.

EXHAUST SYSTEM-Do They Last Longer Than They Did?

 EXHAUST SYSTEM Last Longer Than They Did? Now drivers Benefit

Thinking about this, I suppose that there are many reasons that an exhaust system fitted to a modern car will last longer than say a car exhaust would 15 to 20 years ago. The cars of yesteryear were not subjected to the emission laws that today’s modern cars are. The big change when all cars were fitted with catalytic convertors.

The modern exhaust system  is now aluminum and are longer lasting

In fact it was about 22 years ago that the new cars that were produced had to be fitted with a petrol and Diesel Catalytic Converter.Cars registered after 1st August 1992 (i.e. K prefixes onwards) For more reading… http://www.kgbanswers.co.uk/what-year-did-it-become-compulsory-for-car-manufacturers-to-fit-catalytic-converters-in-the-uk/2247704#ixzz33Z3y8XsB.

This is about the same time that exhaust systems appeared to last longer than their predecessors. In the good old days we used to buy car exhausts from the manufacturers direct in containers. We knew which cars were fitted with exhausts that would only last about 2 years. Certain cars such as Vauxhall Vivas and Cavaliers were very vulnerable for their back box’s rotting; because they used to collect the dilute acid from the engine in the tail boxes and this would rot them from the inside.

Also there was many more of one model of car produced by the manufacturers. I would buy say 100x VW Beetle exhausts, simply because there were so many of them out on the roads. Today because of computers the car makers can alter and change a model, within minutes on a computer and I believe that it is the same with exhaust systems. The designs are much better and are made of better materials than they used to be. We in the trade do not stock the same number of systems anymore because of the large amount of variations within one model of car, where there was one exhaust to fit one model whatever the engine size, there will now be ten different systems and shapes for the different engine sizes, this could be to do with the different catalytic converter sizes that a different engine size may have to have, there for the rest of the exhaust will be a different shape or size.catalitic convertor

The exhaust system has now become part of the emissions service.

We have now had to become qualified in car emissions, using sophisticated hand held computers to diagnose any faults in the system. Also the addition to the catalytic converter onto the front of the exhaust system added the need for a better quality exhaust pipe product, the catalytic converter is made of  a core of ceramic or stainless steel honeycomb, a silica and aluminium wash-coat, and a precious metal for the catalyst (platinum). The car makers then started to use aluminised exhaust systems to match the quality of the catalytic converters and enable the guarantee to extend to two years, on a replacement system.

Your exhaust system lasts longer because they are now aluminised

Previously most exhausts were made from mild steel, which would only last about eighteen months, if that. These were produced by small niche companies who made replacement exhaust pipes from mild steel. Because of the demand for Cheap Exhaust Prices  from the growing fast-fit centres,  such companies as Pioneer exhausts did a roaring trade. Companies like Bosal Exhaust system made aluminised system for the car manufacturers and gradually started to sell their products to motor factors and specialised Exhaust system wholesalers, who would in turn supply garages and fast-fit centres. The only problem was that they were more expensive and would only be bought by customers with up-market cars; the regular guys still wanted the best price exhaust for their cars.

This all began to change with the advent of the changing car market, when fewer models of a certain car were made and they were fitted original equipment on these models. This made it more difficult for the cheap steel exhaust makers to compete as they did not have the flexibility to adapt their equipment to changing market. The larger companies were streets ahead with the equipment they used to make the catalytic converters and exhaust systems with; in fact most of the Exhaust system parts were built very accurately with “robots”. The robots also made a better Exhaust system because they are more precise when welding the parts together. Bosal Exhausts also added a small hole in their back boxes to allow the excess acid to drain away.

The simple fact is that YES exhausts are made from far better quality products and built to a much higher standard,(no dodgy welding) therefore they last much longer than they used to, hence a two year warranty given to the replacement parts fitted.
