I did a little digging around while on the train home, the 2.2 DT and 2.2 DCi have different exhaust systems, crap! I did find a place that apparently does the parts. which looks to be 2 silencers put together on a long piece of pipe.

Its expensive and that pipe will blow the budget I have set myself, being 3x more expensive. I'm now jealous of all you DT owners and standard espace owners. Parts are soo much easier to find, unless someone is willing to sell me a DT espace, reliving me of a few notes. (Although they have drum brakes I think ;( )
I'll have to scour around for a few used ones.
