ill tell you, obx or
www.ssautochrome.com is the worst company to deal with. i ordered a header through them like a year ago before i found this forum to find out that the header didn't fit right since the egr didn't come even close to fitting... sent them like 8 emails and 2 faxes since they dont have a phone number and i even tried to go through the gov't, never responded to any of my emails except for the one asking if they had a header for the 1.6L 200sx, that one they responded in like 10 minutes....needless to say, they are one of the worst customer relations people i have ever dealt with... thank god i finally switch and got my hotshot header
