Default XJ X351 CAT flexi replacement

Hi
On my XJ left side there's an exhaust flexi just after the turbo and before the CAT. I'm having trouble finding on on the Internetnet. Has anyone replaced this part and where can I get this part.
I've attached a picture of the flexi for the 2.7, but ive been told it doesnt suit the 3.0 diesel. I was hoping to remove the 90° and weld it to my cat. But apparently it won't work.
Does anyone have a link for the right part?

It appears that the pipe is part of the catalyst assembly for the 3.0 litre diesel variant.

Have a look at this page from SNG Barratt's UK website:

Perhaps a local exhaust specialist shop can devise a solution?

Yes it is a complete cat assembly but all I need to replace it the flexi just after the turbo flange. I hoping someone has replaced one in the passed and can direct me to where they got the part

Surely there must be an automotive exhaust specialist shop in that part of the Republic, or near Dublin that can cut out the damaged part and weld in a suitable replacement?

Not that I know of. Most exhaust centers just want to swap out exhaust units. I don't mind doing this work myself, its getting this part is the problem. There's not much room to fit a more common longer flexi.
