Okay, I guess that wasn't nice.
3rd gen header basics, again:
1) Nobody makes headers for us that exit at the same location the factory manifolds do.
2) Since 1) is true, everybody exits wherever they want, so either a) you use their y-pipe, if they make one, or b) you have a shop or someone with pipe manipulating capability fabricate one for you.
3) Also since 1) is true, everybody who makes headers for us uses their own type of collector connection, which takes you back to 2) a & b.

That's why people buy the emissions-compatible Hooker, Hedman, Pacesetter, or Edelbrock TES headers as well.
And why some people buy the aforementioned Hedman headers & separate y-pipe.
Hooker is the only y-pipe that is 3" minimum after the two banks join.

yeah im getting quotes for about 250-350 for a 3 inch y. Think that's a little much???
or should i just buy the Hedman y pipe, and then where the two pipes meet, make that 3 inches??

i asked a friend that works at a muffler shop how much he said around 200 to 250.i didnt ask him how much to modify. but i think it would probly be cheaper to modify the headmen pipe

yeah i think that is going to be what im going to do.because 2 1/2 inches in PLENTY for half the engine. and then to go into a 3 inch collector/Cat/exhaust should be great.
