I have a '78 Fox with the tri-Y exhaust, but I am not familiar with the newer
4000 exhaust configurations ... I do have the Bentley for the '87 4000 here in
The only reference information I could find was a picture on page 10.3 of the
Bentley. It sure looked like there were two pipes on the downpipe side of the
connection to the exh man in that book. It looked like the mounting flange is
different than that for the Fox ... mine has a rectangular mounting surface
with six bolts (one on each corner and two in the middle of the long direction.
>From this tiny bit of information I would imagine that you are going to need
both the exhaust manifold and the down tube from the Fox ...
I heard that the VW Fox was basically the same as the old Audi version. Can
anyone confirm or deny this? If so, could you get the exhaust tract from a
newer VW Fox?
