The cat-back exhaust will make more of a difference, with a dual downpipe
setup.
The 4 into 1 manifold is really restrictive...

I just installed the dual manifold and downpipe, on an '87 Golf, along
with a 55mm cat and a TT cat back exhaust.
Instead of using the heated O2 sensor, I had an O2 fitting welded to the
downpipe, and just plugged the O2 hole on the cat.

Dennis Bjork, [mailto:jo301@MailAndNews.com], was amazed how much better
the car felt, more power all around, 
and especially on the mid range and high end.

I have the Autotech 2 1/4" aluminized, 50mm cat-back from my girl's '86
GLi, with a brand new Supertubo muffler, 
there is some light rust, but it's not bad at all. If you want a loud
exhaust, this exhaust is not for you, 
it is right down quiet with the 2 mufflers and a cat. 
Several people have asked about the exhaust, but nobody has claimed it,
$100 plus shipping or a possible trade.

New direct fit 50mm cats are $110, if you can't find a good used exhaust
dual exhaust manifold, 
I can get new exhaust manifolds for $135, and new A2 Jetta TT cat backs
for $180.
