Well i finished installing my obx race header correctly because before i didnt have the right o2 sensor to fit. Its on a 96 240sx 5sp with injen cai and apexi n1 dual. Driving daily is much more smoother and responsive and on the freeway in fifth gear pulls real hard. What i noticed is that before i use to have this surge of power after 3500 rpm but now the power is throughout the rpm band which i wanted. The sound is noticeably louder but not too bad once your cruising but it sounds so nice. The only problem is that the egr doesnt really quite fit but i just use foil tape to wrap around the egr just in case. Overall the header bolts on pretty well and so far no flaws that i see. Im hoping to run my car at the track with this new mod.
