Thoughts on exhaust size for larger displacemnt Twin Cams

Been talking with some people about the size of the header pipes on those of us who have installed larger cylinders.
I have a 2015 CVO that I installed a 117" big bore kit on and the discussion some are leaning towards is that for the larger displacement engines need a larger exhaust.

I'm curious to hear some thoughts on what others think. And then if a larger exhaust is needed who makes a 2-1-2 for our bikes? I've heard that some make a 2-1 exhaust that is larger but not a dual exhaust.

Thoughts?

I have 2015 Road Glide Ultra CVO. Originally was going to go with Vance Hines header with the X crossover. Dealer suggested the S&S Power Tune header. Went with S&S and so glad I did. So much cleaner look with hidden crossover. Also went with Vance Hines High Output exhaust with Carbon Fiber tips. Absolutely love the setup I went with.
