Flexi Exhaust Pipe
A Flexi Exhaust Pipe can get you out of trouble?
Over the past 15 years we have seen a massive change in the way that car manufacturers have changed the way that exhaust systems have changed. In the early days we used to keep
huge stocks of exhaust parts( including Flexi Exhaust Pipe) in stock to service our customer’s cars.
There were many different exhaust manufacturers around at the time supply the aftermarket with mild steel replacement exhaust systems. Some were good quality and some were bad quality. At the time we would guarantee these mild steel systems for one year and they did not last much longer than that. At the time I was a great fan of the Unipart exhaust, because they were perhaps the best fitting exhaust system on the Mini’s which were very popular at the time.
We found though that the worst problem apart from half of them did not fit correctly, was the welding. We had to balance the cost of these exhausts with the quality of the fit and the welding. The cheaper exhausts were welded by hand, and were awful quality. We would have many comebacks from faulty badly made exhausts. Some of these companies are now long gone, but the ones who have stuck it out are the better quality systems. These companies such as Bosal, went into aluminising their exhausts to make them last longer and gave them a two year warranty.
However they would still rot from the inside due to the mild sulfuric acid that was emitted from the engines of these cars.
Catalytic Converters became the new influence with better quality exhaust pipes.
Then along came the big revolution, for the humble exhaust pipe, the emissions test. The new greener car engines started to come out with catalytic converters. This was to control the
pollutants that were entering the atmosphere from the car’s engine. The cats were made from a honeycomb of ceramics and the catalysts that are used are made from precious metals such as platinum, palladium and rhodium.
It is my opinion that was because of the improved status of the exhaust system including the catalytic converter that the whole unit would have to be made better and therefor would last
much longer. In the early days of catalysts, companies set up making up the replacement cats with imported universal units from America, so if your cat went for any reason then the cheapest way to replace it would be to make one up in a kit form including a Flexi Exhaust Pipe and weld it to the old exhaust pipe.
As time went on and the emission laws became stricter, then the cats became more complicated, some having two lambda sensors fitted and Flexi Exhaust Pipe which were also becoming an integral part of the exhaust system. It is not uncommon to find some cars with two cats on the same piece of exhaust system.
This is where our Astra VXR Flexi Exhaust Pipe comes into the equation.
The more complicated the car and engine then the more complicated the exhaust system will be. Some cars even have exhausts fitted that are more complicated to get at physically. They weave and bend into the most complicated places that you can think of.
Some of the cat/exhaust combinations can cost as much as half the value of the car in some cases and when we told this VXR owner that the replacement system for his car would be well over £1000 he nearly fell through the floor?
Fortunately we have a guy working for us who can see his way round these things and Ryan came up with a great solution. He suggested welding a new flexi pipe onto where the break in the exhaust pipe was. This would save the customer hundreds of £’s just coming up to Christmas. All we had to do was to check and see if the exhaust was thick and strong enough to take a weld, and it was.
Ryan measured up the flexi-pipe where it was to be fitted and welded the new part onto the existing exhaust. The guy could not afford the £1000 in the first place and so we were all happy. We can confidently give the guy a guarantee on the job and he went away another happy customer.
