F355 Nouvolari Y pipe?

[geopetrolhead]

Hi

I was thinking about getting a decatted Y pipe from Nouvolari for my 1995 2.7m F355, Is this worth doing? I have Capristo level 2 with switchable valve fitted, will it make a noise difference? Will it cause any problems with the ECU detecting that there are no cats in there?

I'm also considering Nouvolari sports cars too as my right side cat is rattling and it's annoying me.
