Tubular Manifold performance question..

your 2g manifold probably wont crack so its really not worth worrying about.

my 2g mani is cracked, right in the top middle... thats why im shopping around

Just thought I would put my two cents in. If you are willing to spend $400 on a tubular header, I got mine from dsmparts.com, great deal, great price, even better is the incredible look under the hood. The SS look only lasts the first time it gets hot, then it starts to turn colors.
My performance side is probably 10-20hp, but a considerable, and I mean consderable spool up rate. I would say maybe %20 or more faster spool. Is it really worth the $400? Its expensive but it looks great, spools faster, and gives you a little more ponies.

As for fit, I got mine, fits great, ported to 7cm to match my turbo. No problems what so ever. IMO I would go with a tubular header, but that is because I have one and love it.

Here's an even better link about the SS Auto Chrome header on the 'other' forum.

http://dsmtalk.com/forums/showthread.php?threadid=112780

It has some good theory on exhaust scavange effects and how they go out the window towards the end of the discussion.

Personally, I'd say stick with a 2g or Evo manni. I have a DNP and while I do like it, I really can't say it was worth the money. I can't say if it affected spool time since I changed turbo's at the same time (POS 14b

) But once I get my car up and running again I'm gonna do expiramenting w/ it vs. a stock one... If I can find another considering I gave my 1g away.

As far as melting things under the hood

I have not seen any negative affects from it. But it is noticealby hotter under there now...

Ohh and I don't know what kinda crack the guy above me is smoking but they are 495 from DSMpart.com.... http://www.dsmparts.com/dsm_turbo_manifold.htm
Same place I got mine from over a year ago.

And what are you basing 10-20+ hp on?? Butt-dyno or something actually measureable?

Wobble · Mar 1, 2004

how the heck did you bling the shit out of that valve cover like that?? MY EYES!!

69_luv · Mar 1, 2004

Your right, sorry I paid $489 I think for my tubular header, not $400. And yes my valve cover is bling bling. I polished my auto trans as well. I will have pics of that posted as soon as possible. As for the DNP header, yes it was expensive but I did notice HP and Spool. Go for it if you have the turbo allready and can afford the header. Its a work of art under the hood. Yes its much hotter though, I wish I would have bought the GT C/F hood, with the vents, instead of the OEM.

any dyno numbers to back up that 10-20 hp? when you pay a considerable amount for a part, the butt dyno tends to be a little bias

I've been running this mani for a little while now, and I will agree that it definitely sets off the engine bay. I also noticed faster spool up. the heat is also noticeable, so I may decide to get it coated. Looking at makes it hard to do that though.

DN did a outstanding job on this manifold. Luckily for me I have a 3SI friend here that knows Don got me a great deal on one.

SSAutochrome headers are worse in my opinion than the pace setter header. I have seen and used both and they both suck monkey balls, however the SSAutochrome one is worse.

Lets put it this way, that manifold is made by OBX in Taiwan for under $60 U.S. landed. Their factory offered to make our honda manifolds for us. :barf:

Yeah right buddy. Don't you have some cheap cameras to make or something?

Also I would like to point out the SFP manifold is mild steel... but it wont break.

It really depends on how you design the manifold moreso than the material.

The SFP is a really nice peice but for 100 dollars more you could get one made of stainless from DNP.

do the DNP's come with any kind of warranty?

What kind of warranty could you get with that :confused:

Their products are so damn good, that really isn't an isuue, unless someone else screws it up.

Sorry, but in comparison to DNs, that looks like total crap. :thumbdown

i dont think these should give any hp, just aid with spool up time.

69_luv · Mar 2, 2004

I don't think there is a warranty on the DNP. With the cost you would think they would have something. I think that if you had the header, and it cracked where one of the tig welds was and said something, who knows.

By the way that alien header is pretty sick, I like the angles. A little spread out for my taste though, I like the tight wraps on the DNP.

Somebody asked on the dyno, and all I can say is that with the stock mani I didn't dyno, and haven't had a chance to get it on the dyno with the new header yet. I can feel a difference, in both spool and more go go juice. So yeah I guess my butt dyno will have to do. I will get dyno sheets in as soon as I go through my break in period on the new trans and turbo.

The Alien manifold would be tight if it was only competative with DNP for pricing. Shyte, for 800 bux, you should at least get it polished!

they are both gonna discolor when they heat up anyways

True, but anyone who is serious about buying the manifold will get it ceramic coated... I wish DNP wouldn't polish thier manifolds to cut costs for that reason...

those SSautochrome manifolds are shit, at least the ones the made from hondas. they would crack within weeks or days if you didnt add extra braces to support the turbo, and even then they would still crack. not to mention the horrible wastegate placement they had that caused serious boost creep problems..the quality did look decent but they just didnt hold up..unless they have made some changes to the making and or design, i cant see them being much better for dsms either

unfortunately the saying you get what you pay for seems like it fits pretty well with manifolds...you might also check out the south florida performance manifold. they arent as bling as the SS manifolds but they work great.

I concur, the ones made for hondas are crap.

DSMJim · Mar 2, 2004

OK here are pictures of an OBX Honda manifold from SSAutochrome. You can let me know if you want one of these on your car.
