LS3 header primary diameter

[65 drop top]

I just found out that AME offers 2 different header primary sizes for my car, 1 3/4" or 1 7/8". Engine is a crate LS3 525. It's going to be a street car. I know the pro's and con's of using the different size primaries, just not sure which would be better suited for the LS3 525. I was planning on using 3" dual exhaust based on a poll I took on another thread which 66% voted for 3".
