Prelude VTi-R Header

[MrKaji]

yeah your speaking as if youve had all these headers and your saying the one you bought matched them, you cant know for sure

the runner diametres, collector flow designs, bend angles, primary and secondary lengths and head plate port matching are all integral parts of an extractors performance and replicas just dont replicate those sorts of details
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

your exactly right my friend, but again i didnt mean to imply that my set up was better than his. Like i said for what i paid im happy with what i got.
all i was saying is that replicas are rarely as good as the real thing, but if this has worked for him thats great and i think its fantastic that this product is accessible to everyone.

as for opting for custom i went with the intention of getting xforce but a supplier mix up meant i ended up going custom (which also meant i could specify how i wanted them built for my application). i didn't have the funds for going a big brand like SMSP however much i'd have liked too!

even though this replica is cheap by comparison to the real thing, its still relatively expensive. maybe in the future when i get around to doing some head work ill swap to a better extractor, maybe even the one lukathers using!

as for the dyno comparison, ill get a read out when the car gets tuned, which wouldnt give an accurate depiction of the gains of the header, especially if other modifications have been undertaken. Unfortunately the only conclusive dyno comparisons are when 2 products are tested on the same day, at the same dyno, on the same car.
having said that im still interested to see the dyno print out of lukathers car
