Thoughts on this header design?

[Tippy]

Let's be clear here, the headers above would allow more power if the primaries/secondaries were both equal length.

There's folks focusing on the primary size and the reason some are saying it's for bigger power, not because it has shorter running primaries.

Just want to be clear here.

Length/volume affects lag, ID affects velocity. Equal length affects torque curve and horse power.
