Dont go through nopi. they are good but they are costy to. I can probably get you injen intake for a lil less.
I myself drive a 95 Sentra and i plan on modding it . but of course i do basic now like intake header and custom cat back but later on i plan on doing a full GTi-R engine swap.
And also i can get the 95-98 Nissan Sentra Chrome Altezza 3 Piece ( left,center,right) for 260 and also a 2 piece( left and right ) for only 180.
I have the picture of the 2 piece but no pic of the 3 yet.
