Yes the 85+ cars do have the shrouded injectors but they went to that 
in 84 on the JH with the rabbit GTI's & there's no change there. 

On the exhaust system the only difference I ever knew about was the 
hanger mounts, In mid 84 (approx 1-84) They changed from the old 
style hanger mounts (like a hook) to having a rod welded on & 
the rod slipped through a hole on the hanger. I don't think the 
piping is run or bent differently simply because I have sold early 
systems to people with late cars & they had the hangers changed over 
& the systems fit fine. 
As for the difference in HP from 90-94, I dunno!!
My factory engine code/HP/model/years that applied book says 
JH 5/83 to7/89  = 95 HP applicable to Rabbit GTI, Jetta GLI (84), 
Rabbit Conv/ Cabby, Scirocco . 
Even the parts microfische states JH= 95 HP.
Dunno where EC got there info but many factory specks change from 
book to book. Even when I built my RD motor Mr. bently says it's 
10.0-1 compression but the VW service microfilm states RD 9.0-1. 
Jeeeezzz, WHO do you belive???? So I cross referenced piston part #'s 
& all RD's are the same as later 10.0-1 motors. And now that I've 
put my foot in a 8.5-1 motor (or is it 9.2-1 SHAWN?????) I can 
definetly tell that mine is 10.0-1:) (Or is that 11.2-1 
Shave,shave,shave)

Pheeeeeuuwwwww!
