Default Hot side options shorter length vs equal length?

I was just pondering the hotside for my twinscroll T6 S480 and was a little torn. My thoughts are this: Would it be better to have one side shorter or lengthen it out to be the same length on both sides before going into the turbo. I know most will say it doesn't matter on a V8, but I figure every little bit will help. Excuse the crude drawing.

I would think that you would want to merge the two together before getting to the turbo. If merging right at the turbo, no it shouldn't make a difference.

no merge...one goes into one side of the twinscroll turbo, the other to the other side. Divided flange twinscroll turbo.

The instant that back pressure starts to build, It shouldn't make much if any difference either way.

I am guessing with the 92mm turbine on the 5.3 and a 1.10 T6 housing it probably will not start seeing any huge backpressure until at least 5500-6000 rpms. My main thought is to aid in spool up. Shorter tract for one side vs equal length on both sides of the motor.
guestimate of backpressure at 2000, 3, 4, 5, 6, 7.
