As i said looking the same is not being the same.

however i say once more, if you say theyve given good gains and you didnt pay alot for them thats great, and its good youve posted this too share your experience with people

How many headers have you had in your prelude?
im my experience ive ridden in a few preludes from Si H23a to VtiR with H22a2 and H22a4 and by far Lukathers H22a2 has quite amount of power gain from other preludes ive been in.

in addition to your quote about branded orginal goods, i wonder why you ended up getting a custom manifold when you could have purchased a branded header

further more if you say your header has all the gains you state u should post a dyno read out here to and well do a comparason
