I remember seeing an equal length tubular manifold somewhere for the KA's. I can't remember who the hell sold it though. It was ceramic coated.
It seemed like the company's initials where IAP. They said they specialized in WRX and 240sx performance parts. The manifold that they sell is 700 bucks, but it's my ideal manifold.
does anyone know what company I'm talking about? I should have bookmarked it. I have searched for hours with no luck.

Turbo Manifold
Greetings all,
We just wanted to take a moment to cordially thank Nathan for his support and to say hi to the NICO members again.
Red240ne we now have manifolds in stock, ready to ship for the KA24DE, about 2 week turn around on the KA24E. All of our manifolds come coated, sorry if that is jacking the price up ($60), but we are the only company on the market selling our manifolds and kits with warranties. Every manifold you buy from us comes with a 1 year warranty against cracking. That and the NICO member price of $649 Shipped, makes our manifold an outstanding value.
We also wanted to let the members know that we will have an SR20DET manifold available soon. It will be equal length as well, with the same build quality and coating process and same warranty, for the same price to the members of NICO that have SR20DETs.
Nathan thanks again for your kind words and the pictures
Hope to hear from more of you soon!

Both the Tom Rice manifold and the IAP manifold are really nice, excellent quality. But, the Tom Rice is not equal length and is not coated...also, they only produce them in runs of 10, that could take a while 
The IAP is just as sturdy with it's supports on all load bearing things (turbo flange, wastegate flange).

I can't really tell what the quality of that mani is...
From the one picture, it's hard to see...but looks like weld-els slapped together with a 1/2" wide piece of steel connecting the flange to the collector.
Anyone have any other pics, maybe close-ups of the welds???
[EDIT - I just saw the other thread on this manifol with the pics...]
Why have we already determined that this is a great manifold...has anyone used it???
What about fitment???
What about it warrants a $650 price tag (and please don't sell me on the info from the site - I'd like to hear some user feedback)???
Not bashing it or saying it's not great, but making an assumtion based on just that one pic and their marketing info...we need more.

Let me know what pictures you want and I'll take them, it's sitting on the floor of my room, I can go test-fit it too when I get home, it just means I dont get to be quite as lazy as I was hoping to be. What sells me on it: I got it quickly, it is coated, its QUITE sturdy, and the welding is good, also it's black 
, and has a one year warranty, on top of that Marc at IAP was always easy to get ahold of, keeps me updated on whats going on with parts I've ordered and practically does tech support too...a refreshing experience compared to my other experience buying parts from someone (I might be out 4100 dollars AGAIN now, Visa sent me a letter saying they might have to charge it back to me again ).

ohhhhhhh, hahaha. Yea, IAP would be my first choice if I could shell out 650. 650 is half of what I was expecting to pay total, so I don't think that's gonna work.

I don't particularly like using braces on any manifolds. They do not heat up and cool evenly with the rest of the manifold and in many cases may actually be the cause of cracking. Manifolds typically crack because of uneven amount of heat in different parts of the manifold. Some of it is not critical and the ones that are can easily be fixed so that it can be allowed to expand at different rates without putting stress on the rest of the manifold.
While manifolds shouldn't be assigned the duty of holding up an excessive amount of weight, a good manifold without supports should be able to hold up a turbo and pehaps a small load from the exhaust. I say loads and not weight because the weight of the exhaust should be supported by proper hangers. More stress can be seen my poorly designed systems as a result of heat expansion in the exhaust system. A good hanger system that allows the exhaust to expand rearward is best. So no solid exhaust mounts(without rubber hangers) should be used. If you must mount an exhaust solid to the chassis, a flex pipe should be used somewhere after the turbo.
Greetings all,
I just wanted to say thanks again to everyone who has purchased from us and also thanks to all of you for discussing our products on here. We strive to continually update our products based on user feedback, so please, as always, keep it coming!
C-kwik,You bring up a few valid points and I just wanted to address them so maybe as to put your mind at ease a bit. The top support which connects to the turbo flange is welded to the head flange ONLY. We did this, not because the manifold wouldn't support a turbo, far from it. It is there because as I agree with some of your points and we ARE backing our manifolds with warranties, it simply adds some extra support. The support on the wastegate flange is welded to the collector, not an individual runner for precisely the reasons you stated, elsewhere it may have had adverse effects. This support was placed again for longevity. We did massive research on different types of manifolds, feedback from people that had used them and what problems they had incurred. We heard several people complain that the wastegate tube over time cracked and broke completely off in some cases, causing some very unpleasant results as you all can imagine. Wastegates have some weight to them, and when it just hangs there, vibrations occur, then you add heat into the mix and you have a crack. That was unacceptable to us. As we see where your thoughts are on heat distribution, we feel the small amount of varying temperature has little to no effect on the manifold. With the heat coming from both the head and the turbo, the ENTIRE manifold is heated up very quickly, and the small amount of differential is inconsquential. I hope this answers at least the reasoning behind the supports.
LT_Z:
The manifold comes in black or gray only at this time. We are looking into other colors, but I can say for sure that I doubt silver will be considered. I am sorry for that, but the silver we tested had a really bad look to it. Maybe if we find another product that looks better, we will consider it in the future, especially if that's what you guys want. Everything we do is for our customers because without you, we don't exist.
Orion:
Just a note on fitment. The head flange is actually port matched, so if you wanted to for some reason run it upside down it would still fit. The fitment is, in one word, perfect. Just ask Nathan after he tries his Also, I don't view what you say as 'bashing'. It's feedback and I don't blame anyone who wants more, especially from users, before contemplating a $650 expenditure. As always, thanks for your concerns and honesty:thumbup
Thanks again all!

I would guess that the wastegate pipe failure was more a result of poor dumppipe design. Since a dumppipe heats up only when the wastegate is open, it cycles through expansion and contraction much more often and can cause cracking very quickly. A bellow, flexpipe, or even a swage connection can probably solve this, but since you're only selling the manifold, you have little control of what they do with this.
As far as the manifold heating up quickly, yes, it does, but not all of it is at the same temperature. The head flange will likely be much cooler most of the time as it has no direct contact with the exhaust gases and is being cooled through contact with the head. The bracing itself would also be cooler since it is surrounded by cooler air on all sides and would heat up slower since the heat into it would be the result of conductive heat which takes time.
Not to say that your manifold is bad for having this. I was just responding to Nathan's assumptions that bracing is good. Since you are providing a warranty, I doubt I would as worried about the cracking being an issue since you would be replacing it anyways.
Lastly, as far as the port match as a bottom mount, you may want to double check this. If your ports are wide enought to cover the port in either configuration, fine, but if the ports on your mani are an exact match, it will not match if you bottom mount it. The port of the KA is not centered between the studs. Just hold two exhaust mani gaskets up to each other with one of them upside down. With the holes for the studs lined up the ports will be off by about 1/4 inch.
