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 
my office.

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.

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?

HTH!
