Can anyone tell me how many pieces are mounted on my car, and if they have to be replaced alltogether when they give a failure in the exhaust
the vin is SAJAA72PO3SGO1264
And yes, if you get original parts, you they will fit together and you will only need to replace a defective part. The same should apply to parts made to OEM standard. The probem is that original parts (or made to OEM standard) are hard to find, and in that case I cannot comment on the fit of other parts.

thanks for your reply. However, my catalytic repair shop says that there are 4 converters?
If you look under the car, you will definitely see only TWO catalytic converters, one for each bank.
They look like this, the picture is taken from the Jaguar parts catalogue, and in reality they also look exactly like in the picture. I have had my car on the lift enough times to know, and I have already replaced one of them.
After the catalytic converters, you have the middle silencers and then the end silencers. You can easily check the setup vial the link I have posted in my first answer.
What you mechanics might refer to, and also the text posted by rsa760041 might refer to, is the fact that within each catalytic converter there are two cell packs, with an oxygen sensor placed in between them.
Each cell pack could also form a separate catalytic converter if packed into a separate enclosure, but this is not the case with our cars.
So, technically speaking, it could be considered that the car has 4 catalytic converters, but if you talk about the catalytic converter as the part that can be bought as a spare from Jaguar, then you only have ONE for each bank, as shown in the picture.
Everything else would mean buying the internal cell packs, opening the enclosure of the catalytic converter, replace the cell packs, and re-weld the enclosure to close it. Maybe your repair shop is talking about this procedure, instead of a spare part as sold by Jaguar.
The point is that normally, when you speak about catalytic converters, you talk about the part to be replaced "as is", and not about replacing the internal cell packs.
Best regards,
Thomas

Reason: Typo
2 catalysers on xj6 and xj8 and xjr and super v8
i have 3 2003 cars g08679 g23600 g 5 and someting another g5 and something build the same day . And even the x356 daimler H18000 with supercharged 4.2 only has two I ve been changing one of them.
your car is a very early one 2002 or 2003
On your catalytic converter should be a part number plate, in my case 2W93 5E212 ED. The middle part 5E212 references to the catalytic converter body, many Ford cars have the same catalytic converter installed with a different part number in the beginning, which refers to the pipe fitting. I got my catalytic converter repaired for about 200 USD by an exhaust shop. They took a good used Cat from a Ford breaker car which had the part number 5E212 in the middle and transplanted the cells into my cat. Works perfectly.
there was another thread recently for catalytic converter replacement for a supercharged, there was a link to a seller on ebay who is selling a pair of cats direct fit for as little as 150 USD. Not sure about emission testing and durability, that's why I went with a used OEM cell.
mine got damaged when accidentally hitting it during transmission install.
