What you guys reckon to a nice stainless backbox on a fabia sdi ?

Will this make any difference performance wise and look and sound any better?

cheers

Performance wise... no not a hope IMHO.

Sound... it's a diesel so nope.

HTH

However, 1 out of 3 ain't bad!

Should look better - especially if you found a vRS bumper so the exhaust could sit in a gap rather than just poke under the flat bumper.

Looks are subjective.

Performance - not a hope

Noise - It's a diesel, so you'll not get much noise even if you run a plain dump pipe out the turbo. DAMHIKT!!

Gald you asked though as i'm thinkin of putting one on mine as well. Think it will look very smart, so go for it! should make some exhaust note surely, even if its just a bit more throaty than normal, would be worth it.
