For the most cost effective upgrade/gain, go with the dual outlet
manifold and downpipe first. Then the 2" system later. That C-clamp
manifold is the weakest link in the VW exhaust system. Updating to the
better flowing manifold is the way to go. I've managed to get 117hp at
the crank from my stock 1.8L JH motor with this exhaust system and a
stock cam on my DSP Scirocco! Even the Potterman is surprised as to how
well my car scoots in its current DSP legal configuration considering I
cant really touch the engine at all. With a cam, you should really feel
the benefits more so.  
HTH!

Oh, I dunno if this was something as a bonus for my situation but I have
a diesel exhaust dual outlet manifold and a Eurosport dual downpipe with
the ox sensor hole in the downpipe. I may have stumbles upon some extra
ponies with this setup compared to the gas dual outlet manifold. I dunno
for sure. <shrug>
