So is there a difference between 92-95 ex/si and 92-95 dx header? I have a header but dont know what it's for (know it's for single cam), but some guy keeps asking if it's off an ex or si (d16z6), was wondering is there a difference at all between ex/si and dx, or any other 92-95 (cx, vx) that don't have the cat on the header? Helpful input is appreciated. Thanks.

By the way, the one I have has the o2 on one of the runners at the top piece..
