Well im in the process of building a ls vtec right now with ctr pistons/ type r head etc etc. i currently have a dc 4-2-1 header for it but i would like to pick up a different header that would flow a lot better..

wat do u think the best bang for the buck is? i was kinda looking into getting a bisi one but i hear there pretty hard to come by..

 

IIRC, Bisi is having a special right now on HT for his header.

 

hmm really? ill have to look for the post.. i was almost looking at just getting the RMF replica.. there fairly cheap and seem to have some good numbers

 

the narrow replica header is nice
just wish they made the drag replica for b-series

 

Consider a custom...

 

Consider a search it has only been asked 6 gazillion times!

 

"Best" would be something made specifically for your application, not off the shelf.

PS - You will make more power using JDM P30's or PR3's instead of PCT pistons.

 

i would chose the bisi ased on there having a sale and great quality header and outstanding customer service

 

The Bisi units can be considered custom, though I don't know how in-depth it goes. I have one for my SOHC and it's pretty nice, although I didn't get some of the modifications I wanted; but for the price you can't really complain(I'm going to assume the only changes are runner length which are optimized specifically for the setup you give them on the sheet).

 

bruns spec header
SSR(danny tran is the man)

 

If you are not going to get a custom header, just search for the threads on header comparison tests.

 

jerry built tri y

 

Exospeed has an awesome header as well. Its a little pricey at around a grandish.

 

SSR might help you out

 

My fault. I meant SixSigma. Sorry I got the shops confused. Their race header, side exit is $950.

 

well i made my decision and i went and orderd a RMF narrow replica header today.. i couldnt beat the price and the dyno numbers i have seen.. thank you for everyone replying

 

best head giver is your mom

 

haha f@ck you brian

 

I had a tri y on my b18c5. It worked out, put sat way to low to the ground. I now have a rmf narrow header and it sits nice and seems to flow well.

 

the "best" header is one that is designed not ony for your "specific" motor/setup but also for your "specific" needs/goals as well.

if you have a daily driver then a tri y will yeild the best midrange performance

if your looking for top end power for drag racing then a 4-1 header will make the best peak numbers

 

hytech replica header OH my god!!! my car improved everything, even had output the DC 4-1 in peak power and 4-2-1 are not for peak power!
as you in USA say "the best bang for buck"

sorry for my english I am from Argentina.

 

i have a Mugen header, but im lookin to get a ASP header
ASP is a shop in WA, state

 

i just orderd the RMF narrow replica header.. i got a good deal on it but i paid for it last week and i sent him a pm the other day askin for a tracking number and he hasnt replied :/ i hope nothing fishy is going on
