that is my new header...can i get some suggestions and pix of 4-1 header fitment w/o getting a new crossmember...i will get one sometime..but the stock one will have to do for now

 

Hmm... I don't know much about header design but something does not seem right about those. Anyhew, for a B-Series motor I think you may have to get a BFH and make the crossmember have some clearance for a 4-1 on a B-series swap.

 

well i dunno..but if you look at the primaries....they are shorter, then at the bottom get bigger, they are made to clear a civic crossmember at opposed to an integra..will see when i get em

 

looks like it may work but may harm performance as the change in the flanging

 

Those pics suck, anyways you have to cut the cross member, do a search.

 

bling bling!

 

First thing you should do is send that header back. Next thing you should do is search, your choices of headers that will clear an EF with a swap are VERY slim.

Why should he send it back, in the advertisment it says its a dc s, if that means dc sports then its a decent header.

I could be wrong, but I don't think that's a DC. Plus, what little I know about header design tells me that tappered primaries is not a good idea.

I don't think it is either, thats why I said the ad sucks. If its not a dc sports take it back.

 

well i will be better than the stock manifold..i have seen plenty of cut crossmembers in EFs...i only paid 118.99 shipped....i have a friend with a GSR that has the hots for it. he has a DC sports 4-2-1, most 4-2-1 will fit, i am also changing to a 4 wire O2 sensor.....

Only 120, I have seen nice dc sports headers going for 140. Atleast thats how much I payed for mine was, anyways you have to cut up the cross member with a 4-1. with a 4-2-1 you won't.

 

yeah, i just want to see someone's pix..i have not seen them lately....and if all else fails...he will give me 50 bux and his header for mine

Is this true on all 4-2-1 headers???

absolutely NOT. i have a Vibrant 4-2-1 j spec header and i also have to modify my front crossmember. maybe he should have said most 2 piece 4-2-1 headers fit, but, my 1 piece 4-2-1 primaries don't merge with the secondaries until the base of the header, so, i sits very similar to a 4-1 style header.

Most will

 

well guys you are really discouraging...but eh...when i get it, i will see about fitment...and for the price.....i can stand to save up for a jimfab croxxmember.....just put it in the garage and wait!!

 

this one would be an ebay special.....118.99 shipped...got the power gain i wanted, but the noise is kinda obnoxious
x-tune brand

lol power up to 12 hp!!!!!
ya right more like 3

 

yeah i am sure that is pretty close.....i really needed this header..my **** was hell of restricted!! ITR cams....need something bigger than the B16 manifold

 

Where does it say primaries are tapered?.....................................I don't see it.

There IS a typo in the ad, the picture is a 4-1, NOT a 4-2-1 like is in the text.

 

Bah........ITR, still milder than Skunk2 stage 1 cams. I am running M20 Rocket motorsports, milder than stage 2 cams and as much as you want to run with stock compression.

any 4-1 is going to breath better than you will need with ITR cams.

 

meh...well it breaths well for me....i did not loose any power anywhere in the band...just got more over 4G RPMs...i will have to tune more later..
