The arc intake has been proven multiple times to lose power. It is purely a cosmetic addition, which is why it is not very common.

Can you explain the dyno a little more. What parts were on when it ran 249 and what was on when it ran 256?

Ok

257 parts are ARC intake, TP invidia, Invidia dual exhaust v3 without siliencer
249 parts are ARC intake, TP invidia, Greddy TIC single exhaust without siliencer

so many variables to list why you saw a "power" change. Could be your mods just do not work well with one another. Instead of looking at the power number, look at whether or not you had gains within your powerband. Like dc2 said that intake does nothing for performance, however, you will have a gang of teenage boys gaggle once you pop your hood

for the greedy the duals yield more hp than the singles

Ok...look at this

https://www.s2ki.com/s2000/topic/651...e-dyno-charts/

That is one of many dyno proven greddy gives more gain then Invidia. Most of s2ki member says single exhaust gives more power then dual and I'am looking some "mistake" on my car ?

singles do NOT yeild more hp/tq than duals, only in some cases for greedy the duals yield more.

I have to disagree, do you have any posts or articles with some back up of that?

There are some duals that have gains, but overall, more singles do make more power than duals.
