performance headers

what are the best performance header for a 89 hatch si, greddy, obx, mugen, dc....or anyother ones.

Well lets see....

I dont think mugen makes one for a d-series. Obx...eh? DC is good and greddy. I dont know what you're lookin for exactly on where you want power. Search and you'll find lots of infos.

obx's have a lot of horror stories

go with the dc 4-2-1, they have a decent header

I found a nice pair off Ebay. 100% stainless steel- no bull, cost about $105 shipped.
Shop said it was a real nice set, all the flanges sanded down real nice.
I'll have some pixs in a few days. not sure if they would fit the si.
im sure hes got somthin else

yO thats made by aerospeed! Thats even worse than OBX! Dont believe everything what they say! They bullshit just to sell.

ohh well, looks like im out...

cant wait till i get the engine swap, sobody can have these then..dam

Well atleast you didn't pay too much for them. :)

You must be high. Aerospeed sells decent stuff. I'd trust them before OBX but that's just my opinion. I've been using Aerospeed adjustable springs for 2.5 years now without a hitch with some pretty intense driving and they have never given me any problems. I also have an RS Racing Muffler made by Aerospeed and it's okay too... SS with decent welds. Don't listen to all the hype...

If you want my 2 cents, get a ceramic coated DC header because I know for a fact it'll sustain high temperatures including a fire...

i have a supersprint header, not sure ifu get them in the states, i love mine, the quality is great on it

You're only stating your opinion...fine. But heres what i've seen with my eyes....

Both are shitty products. Oh and my friend did have there coilovers and it CRACKED in 4 months after he had them installed. Trust me i wouldn't diss the products unless i've seen them fucked up. My boys obx header for the b16 cracked from the welded flange. So yeh i think that says it all.

My friend has an Aerospeed coilovers and a header. He's had them for about 8 months now and they are both still perfect. If your on a budget then I would say go with a generic name header, but if you got the $$$ please get a DC Ceramic 4-2-1 header.

yea, for the price, and the way they look, im happy, but if they crack, or somthin goes wrong, belive me they will be sending me another set!!

so go with the dc headers...which ones the ceramic or stainless whats honestly better

i've had my obx set up (header & catback) for almost 2 years and everything is fine...the catback system just needed the holes drilled bigger.

nice pic in car domain ; p next time i'm up north i'll swing by or somethin n check out the ride :)

stainless looks better but somewhere i read ceramic is better...not really sure but anything is better than stock :)

Ceramic is supposed to hold the heat in better. Which is supposed to give you more power... Definitely go for a 4-2-1 tho. 4-1 kill lower end torque. Another thing I read in a engine magazine the other day is that the length of the first 4 pipes determines where the peak of your powerband is. Longer the first section of piping, the higher rpm you will peak at. Shorter makes lower rpm.

Bisimoto is the best you can get. AN-R has a bisimoto knock off that looks really good too. Gonna cost you $500 and on up depending on which you get though.

Like I said my buddies Civic HB is pretty much almost all OBX parts, obx fuel rail, obx header, aerospeed exhaust, obx intake manifold, cosmo racing fpr, cosmo racing air-intake. All stuff off ebay for mad cheap and his shit runs like a mutha fucka! Had if for about 8months now and shits still perfect.

Yop Bisi headers are the best, I like his design and everything...when I'll get some money I'll buy one for my B16

The best of all header? I dont think so.

The best of all header? I dont think so.

so what IS the best of all header o mighty one?

SMSP. I heard nothing but good things about it. I've seen the dyno sheets from this guy who has the 00 yellow itr and got 18 whp at this place in chicago called garage kwai.

so dc ceramic or stainless..which one should i go with for a sohc d16a6 with a full catback exhaust

ceramic

For the price that Bisi costs I think it's the best in that rang, as far as those comptech,SMSP,hytech,AN-R headers goes there are all over 1300$

omg...i'd never spend that much for headers!! That money could be put into rods and pistons, or a turbo kit or something that would get u higher gains

but i guess the high end headersare for those who've already done everything else and are rich and starving for power

But its worth it ;) I know i'm gonna get me the SMSP for sure.

I don't see what the big deal is with the header, I mean they are a piece of metal tubing, if it crack you just weld them up and put it back on, no big deal. Tho ceramic is a different story. So if the cheap ones come in the same setup 4-2-1, why not just reinforce the welds and have the same exact product as the dc/greddy headers for cheaper?
We're talking .000032hp difference here in the header, so I can't see justifying a $500+ header unless you are going totally on aesthetics.

SMSP. I heard nothing but good things about it. I've seen the dyno sheets from this guy who has the 00 yellow itr and got 18 whp at this place in chicago called garage kwai.

Bisimoto header made something like 9whp on a STOCK d16z6. Imagine what it would do on a high compression modified motor. For the 500 price tag...I dont know what smsp sells for but I would argue the best bang for your buck is the bisimoto header. It looks badass too.

Bisimoto are the best headers IMO AnR are close but not as good as Bisi

Bisi and ANR header's are made by the same people.

Notice the similar design?

www.importreview.com (http://www.importreview.com)

CHeck out there test on different header set ups.

Ok good for you they dont test it against the bisi header so how can you say it's better or worse?

How much does it cost?

I dont really know how much they cost but i'm sayin that they've tested popular headers out there. So i figured they might've tried out bisi header. I'm not too sure though. If you think about it, why would he claim SMSP header is the best? He wouldn't be sayin that if he only tested out 3 or 4 different headers. That would be stupid. I'm not sayin bisi is bad but whatever. If its cheap then grab it.

I think this kinda gets interestings...

SMSP header are not 1300 dollars either from what the guy is sayin on the second link.

the motor made 211whp with the smsp and 217whp with the bisi header.

He cries that the smsp isnt setup for that kind of motor bla bla bla. I think that guy is a fanboy of the smsp header. I like bisi because he is real, no bullshit no ego, straight up number's and fact's.

I dunno man. I mean he did test out bisi or something alike and made 7whp more.

stated on the 1st link a guy tested out the bisi and smsp header and bisi made more hp.

I dont even know why im arguing which is better because I wouldent buy neither.

Well importbuilders is one of if not the best tuners and he tested it out against smsp. Smsp came out on top by 7whp. I'm not sayin BISI isn't bad at all, especially for "500" dollars.

The guy sound's like a big asshole I would never take my car to him.

It's funny how his tests show the smsp header putting down more power but then other people dyno the same thing and get totally different results.

Show me other results then. Like i said hes probably the best tuner out there. I hear nothing but good stuff about him and his company. I dont know why you're callin him an asshole.

Look at his replies on his forum's and just the way he type's on the graphs...

Yea if I would have built the motor it would be stronger blah blah he just comes off as hes the best and no one can touch him.

The 1st link you showed me it had someone from a shop saying the bisi header made more whp on a 1.8L motor than the smsp.

I had those prices on those 4-2-1 headers
and they were all way over 1000$ and I know
that one was obver 1300$ I can't find link now but I'll try to find it and show it to you I know they tested a few of the best headers

CYA
Bisi rulzzz :0)

Heres a pic of my header set up.. pretty nice for $ 105

Yeh but then he tested out himself and got the smsp 7whp more. Shit he only wants his customers to have the best and save money. It seems like he loves to prove ppl wrong. I mean thats what i'd do if i was a tuner. I wouldn't talk shit about other products unless if i tested it out and prove there claim is false.

I seen nothing about him testing the smsp vs the bisi header. I seen he did it against the ANR header but nothing on the bisi.....

Hold up let me find it

read the last three post on this link...

http://www.importreview.com/forums/showthread.php?s=&threadid=145&highlight=Bisi

COULD have been that one

He said it LOOKED like that one, AN-R and bisi header's look alike. He doesent even know if it was a bisi or AN-R or if it was a knock off from one of those.

You have no argument...

Thats why i said in my previous post he said he tested one like it or if it is bisi.

I have no arguement? I can care less. Its not like a presidential debate. Nobody wins anything so dont take it seriously for real.

The past couple of day's you have been arguing that smsp is better because all mighty mellowboy always has something better than everyone else.

Who says i'm better than anyone else? I've researched and i've seen one in person that put out 18whp. Theres only one all mighty and dont you dare call me that again. Seriously theres so many dickheads in here its getting out of hand. All i'm sayin is theres something better out there and makes your moneys worth. str8 up dont be an asshole. Arguement is so stupid on the internet. Its pointless.
