Default Single or Dual cutouts

I have Kook's 1 7/8" headers and a Kook's catted Y-pipe. My car makes around 550rwhp. How much of a difference would there be ET wise from running dual cutouts in the y-pipe vs. a single cutout in the y-pipe???

I dont have experience with actual power gains. But am going to but putting two 3-1/2cutouts in the y, as close to the headers as possible. Should be loud, and as close to open headers as you can get.

I dont see a reason to put one in the middle of the exhaust... but thats me.
