Want to mod my Nismo but soooo confused

For what it's worth, F.I.'s 2.5" TDX is probably the most efficient bolt on you will get. Do drop ins filters and hard pipes (those may be custom), then you can see if you want to do more than tune. Maybe HFCs or TPs, but I wouldn't know. I went from 2.5" TDX and high flowing filters to twin turbo and 3" TT-TDX (well more than just that, but you get the idea).
