Nobody makes headers that attach directly to the factory Y-pipe (which is probably a good thing). So, there are two possibilities here:
1) Buy headers that have a Y-pipe that go with them (an emissions-legal set, like Hooker 2055HKR or Hedman 68481, or the non-emissions Hooker 2460HKR and 16767HKR Y-pipe). You can't mix & match brands between headers and Y-pipe, because each header manufacturer uses their own collector location and type.
2) Buy shorty headers without a Y-pipe (like Hooker 2460HKR, Hedman 68470, etc.), and modify/fabricate. Either modify the factory Y-pipe to attach it to the header collector, or fabricate a complete Y-pipe to the cat/I-pipe.
