Then there’s also the debate about performance gains from a common plenum (you know, if you like reading internet debates without data [emoji1787])

But I like the ITB noise. It’s the wind that kills me.

There is some interesting reading there. That second one seemed to devolve quickly. As mentioned in that thread, ITB's have basically no plenum, I am just looking at building an inlet to a filter, something like the old MFI inlet top, so I can aim the filter rearward and hopefully direct the induction noise away from the cabin. No idea if it will help, but it is worth a shot.
