Help not sure what centre pipe to use

[Morganator]

So need some help. Previous owner had the exhause systrm setup differant from factory. Instead of the centre pipe being one complete including rear silencer or mid silencer and rear silencer. They just used a streight through pipe off the end of the dpf to the rear backbox. Now its heavy corroded and a hole in it, it needs replacing. But cant find what they would have used that has the exhaust mounting brackets . Hopefully the pics help

First, start by telling us which engine block you have in your car.

Photos aren't much help to us.
