i'm trying to pick one of the two for my b16 with i/h/e. my future plans are to do a b20 or ls bottom end build up and ofcourse head work. the vibrant is stainless steel 4-2-1 w/ 2.5" collector and the DC sports is 4-1 w/ 2.5" collect (it's also freshly jet coated). both headers are brand new and in same price range. which one should i get and what's the diff bettween 4-1 and 4-2-1 again? is it torque,midrange and topend...i know some of you are gonna suggest hytec or rmf blah blah blah...but it's for what i have right now and my buget. thanks for ur help.

 

when you help your self it will feel great. thats a Question that you could look up on hear. it all depends on how you want to drive and wat not.
i would go with the 4-1 header. i hear the vibrants arnt that good. dont know why just wat i heard.

 

I just got a DC stainless 4-1 header and did the 2.5" collector mod. Not sure how much power it makes over the stock header. If I would of had the cash(425) I would have gone with a profab, but for less than 1/2 the cost (I bought the header used for 100, then the colllector mod & fixing the dents on the bottom was another 110) I like it a lot.

 

If you're going to swap your short block, might as well just wait and buy a nice header after your b20 upgrade. stock isn't all that bad...patience is a virtue

 

I have a used DC 4-1 with 2.5" collector mod. no dents or anything. hit me up ill hook u up.

what's profab's their site? where are they located?

 

the Vibrant is 10 times better quality and makes good power. it also has much better ground clearance than the DC 4-1. my boy made over 200whp on a built 18c1 and BC3+'s with the Vibrant j-spec 4-2-1.

 

if your gonna spend $400 u might as well save up some more cash n go with rmf, smsp, toda, rage, etc..... it's just a couple more hundred dollars depending on which header u go with.

 

DC 4-1 Vibrant 4-1 Vibrant 4-2-1

 

j/w, why would the Vibrant 4-1 be than the 4-2-1 ?

 

the 4-1 doesn't retain enough back pressure to make good torque on a small displacement motor. I have an ls/vtec with a gsr header on it that out performs the jdm itr/d-c sports/ and a few others just because of compression and back pressure.

It is more complex than back pressure. look at this link it has some good stuff. Dan

No its not peak #s mean diddly squat, I also would like to see a 17 hp gain with just a header.

Also how it goes under the curve.

 

search for the thread. they put it on a b16a crx that had only an aem short ram. 17 was peak yes BUT he listed the gains throughout the pwer band and it was something crazy like 10hp at the vtec point. it gains from 1800rpms and up. hell ill find the thread. stand-by.....

 

and here we have it...

131hp to 148hp. most of the gains are from 6k and on but it clearly gained everywhere.

my buddy ran a DC 4-1 with a 2.5 collector back in the day, it ran super hard...

If you want a b16 header go with a TODA..but if you want a header for a B20 go with a DTR custom header..
