Y-pipe question

I have some stainless shorty headers that came with my iroc and I was wondering if I can use the stock y-pipe and if not which one to buy? Thanks,

chances are no it will not work with the stock Y-pipe and reusing it is kinda dumb (no offense). Depending on which model you have they can be as small as 2 1/4 inch pressure bent (so smaller at turns), so it kinda negates all the headers goodness.

You need to know who made them to know what pipe you need.
