Just changed my extractor and downpipe(plue the flex joint) about 2 months ago.
So I have the original GTI parts you're looking for, but your offer price is a bit too low.
PM me with an offer and let's see if we can make a deal ;-)
Pic 1 - Remove the original regulator with 2 screws, first remove the two hose that is connected to the regulator one with the clip and the other one is the vacuum hose.
silent night holey night..
screeching tires all the night..
turning corners nice and tight..
wailing turbines with all their might..
shifting gates so short and right..
passing blocks like cops are mice..
