The stock manifold has proven efficient even at ~900whp. With some decent headwork and the runners perfectly specified to the head flow characteristics, I could see some decent gain from this type of plenum, but other than that, it’s more of a cosmetic improvement, IMO. With that being said, if you do choose to run this as a aesthetic enhancement, it doesn’t seem to “ruin” efficiency in turbo applications, at least.

These things are popping up for every application. The Chinese are very good st looking at s picture and producing. I doubt there is any engineering behind it.
I was looking at on for an n54. I would not use it as is, but they have done all the light work. Cut it up, clean the welds inside, port match to the head, add bell mouths; a decent starting point.
