You could try posting in the tech lounge but here's what I know.

The box is there to improve the engine sound and quite a few on here have taken it off to improve the air flow.
Most use a straight through pipe section and big Jubilee clips.

I think it give a modest BHP improvement :D

I think it's there to reduce drive by noise - It definately sounds better and louder without it.

There's actually an OEM part available from alfa that doesn't include the resonator box as shown in the attached image.

P/N: 60598644 (I'll check this on my invoice tomorrow)
