The CDA is a contentious subject, some rate them others don't.
I think someone on Alfa 156.net tried one on a dyno and gained 1bhp on a 2.0 TS over the stock air intake, and that was without the GTA inlet pipe.
The GTA intake on the stock air intake also gave 1bhp.

You can pick up a cybox stainless system on e-bay for £240 plus £75 for a slienced de-cat. Thats what I would go for, I would make sure I got a silenced de-cat though as otherwise they are supposedly too loud.

After that you are looking at mild road cams and custom mapping which should give around 180bhp. If you go for any hotter cams you will have to get the head ported for the best effect.
