The S tune (R tune?) is NOT as good as the Nismo OEM H-pipe in terms of power.
Most gains will come from swapping out the cats with either HFC's or TP's.
I don't know what the FI exhaust is going for, but my guess is that if it's, say, a few hundred more than someone's used OEM Nismo H-pipe cat back, the gains/sound will only justify the price differential if you have money to burn.
If I were you, I'd just get the HFC's.
