K24 inlet manifold options

[Nathjkent]

Hi all.
I want to start doing a few little upgrades to my k24 type s . First off, intake manifold and induction kit.
I've read online that the standard fn2 civic type R RSP type manifold bolts straight on with no modification needed.
Has anyone done this?

I think best thing to do would be, Reflash, headers(exhaust manifold) HFC or decat.
I've read that inlet manifold can decrease low range torque on the K24

the plan is to do all that, intake, decat and exhaust, and inlet manifold then reflash
