VR6Will pointed this out to me over on CGTI in my 16V Syncro manifold fabrication thread (http://www.clubgti.com/forum/showthread.php?t=236232).
This:
So I understand what the idea is: it’s to be used with a 16V Scirocco cast manifold, which I know to be useful in 16V Syncro conversions because of the position of its downpipe flage. I actually bought a 16V Scirocco manifold and still have it sat in the workshop as I was going to go down this route myself (but I’ve since started to just fabricate a manifold that will work with the normal G60 Syncro downpipe).
But what is this seller actually selling? As far as I know there is no off-the-shelf downpipe like this; to use a Scirocco 16V cast manifold you have to modify the normal Rallye/G60 Syncro downpipe usually. But that looks almost original.
Any ideas?

Here is a translation
An alle die Ihren Syncro auf 16 V G60 umbauen wollen benötigen dieses Hoserohr zusammen mit einem Scirocco Abgaskrümmer
So habt Ihr das Problem mit dem Krümmer und Hosenrohr gelöst.Wollte selbst umbauen ! Aber aus zeitlichen Gründen komm ich nicht dazu.
Passend an orginalen BI Kat. Es darf auch geboten werden nicht nur beobachtet !
I was going to use this myself! But due to time constraints I do not come to do the rebuild.
Fits to orginal twin Cat!
looks original, but like Trev not aware of what it would come from?
Passat G60 Syncro, Golf G60 Syncro & Rallye.
Definitely not a G60 Syncro / Rallye downpipe, or certainly not one in original state; the top flange isn’t angled like the G60 Syncro / Rallye one (see my manifold build thread).
I have a Scirocco 16V cast manifold which I was almost going to use for my 16V Syncro conversion, and the G60 Syncro downpipe could certainly be made to fit it with modification – but would not fit as it is.
It must be a G60 Syncro downpipe as you say Chris but perhaps modified very cleanly using TIG and with exactly the same grade of stainless, or something…?
no 02 sensor outlet aswell, and its angeled different. and it seems bent? some homemade crap?
Let me find my photos of the std G60 Syncro downpipe.
Here’s a poor image that shows the angle of the upper flange of the downpipe on my G60 Syncro.
Also note that the dampers (whatever you call them!) are located differently.
Yes you are correct, it is not a std G60 downpipe!
looks to me like this is modified to fit a regular fwd G60 manifold in order to use the bi-cat system…
could possibly work with the syncro system, altho some of the nuts will be extremly hard to reach
