Can you send a pic?

I have a 2.5-16 exhaust off the car at the moment and if it's what I think you are talking about then I might know somewhere that can make one up.

Do you mean this bit?

Yes, i guess we have the same flanges/pipe beginnings on Left or Right driven cars.
What i can remember now is that the flange on the biggest end is 114mm wide and the thickens is 21mm.
This part could be re-made if you put some effort in to a drawing, but the problem is the cone for the pipe...
The pipe is going from 61mm down to 51mm at an angel of 20degrees and 2mm thicknes...stainless steel... :-/

Why iam asking is:
If you want to produce an descent full flow exhaust you need these parts for starting working backwards...
And to cut your original catalytic part is not a good idea as it cost 2300eur as new part...

So if I took this exhaust to my supplier and asked them to copy the downpipes would that be what you wanted?

I have spoken to some suppliers in motorsport recently who do one offs for us at JLR who might be able to do it. If you can do a rough sketch and upload it then we can see what we can do. ;)

the ends that connect to the manifold are called olive joints and the sizes should be the same for LHD and RHD cars

Johan,
If you have access to a lathe and a press, you can make a mandrel to form the tube ends and build your custom downpipes.
