Well O2 sensor I am 99% sure is ok. I think a hogan downpipe would be better (Hogan performance) . Also make sure you have someone to weld it up to the rest of the exhaust.

Forget it.
You're not outflowing the stocker, because you don't have the double-walled downpipe like the Series 2. The ID of your DP is already bigger than the S2.
You don't shift or rev to the higher rpm'* like the S2, and don't require the same exhaust flow because of it.
Even with ported heads, 1.8 rockers, and a buncha other stuff, I'm not outflowing my stock downpipe.
Spend your money where it counts.

Some physical reasons it won't work are: Different firewall location, rear manifold exit location, and different style manifold flange.
If anything you'd be better off getting a 30 and 45* mandrel bend plus a new flange and get and exhaust shop to chop and weld it for you.
But, you already have a relatively beefy DP to begin with..
