Apexi N1 Exhaust - any experts? (see pics)

[udi]

I'm looking at buying one of these setups second hand, just wondering if someone can help me confirm whether it's genuine, and whether it's for the S14 or S15.

There are some small differences in piping and mounting that I'm worried about, trying to make sure the one I'm getting won't sit awkward or anything. It has the apexi engraving so I'm fairly sure it's legit, but I'm not sure which car it's for.

Appreciate any advice
