You are bringing up a good point. In some cases.....dual exhaust could be a way to balance weight. It can also be a way to pass sound tests. Maybe two exhausts can be smaller than one . Maybe two small are easy to fit? All of this comes to mind....
The real reason is halfway lame. The real reason is looks. In Japann, two exhausts are a sign of great power. Notice the Hayabusa and zx14 come with dual exhausts. Its what they do.
I like the look and went with duals on my leo vince/ arrow set up. Feel free to do as you wish. On our stock bikes, the header pipes are too small. You could let it exit into 72 pipes and it wont change that.
as far as backpressure goes, you want zero. A small amount is too much.
in saying that, that means youd need to tune the fuel mixture coming in. If you dont do that, it could very well be a bike or car needs back pessure to run right, but if you have tuning ability, you want zero.
Thats in a world where oir bearings are friction free and no other considerations given other than peak power.
If we want more low, or midrange. And are stuck with stock cams, stock pistons and porting, now we might start feeding some back pressire in to achieve this, but it will cost us elseware.
