OBX Mitsu Flanged Tubular Exhaust Manifold

[1gDSM4g63]

Exactly, the price you pay it what you get...

You'll probably never get a proven answer to your question on how the Pacesetter compare performance wise to other tubulars. You cannnot make an statistically comparison on the performance by one person to another person's word and I doubt anyone has gone from eBay knockoff to DNP to Pacesetter in the same car or setup.

My assumption is that Pacesetter manufacture has done the engineering and flow testing, but won't release the results for a reason. If the flow test is decent or very well without a doubt Pacesetter would release it or make it a proven fact to increase their revenue instead remaining remain their sales per manifold at 150 bucks.

I personally use the FP race manifold and I really like it. However I have yet to see one single person on this thread who actually has the manifold he is talking about to give a solid response. I would like to hear the answer to the original question, from someone who actually OWNS and USES this manifold. Anyone can make their own judgements from pictures of welds and what not on ebay or any website. But how about from someone who actually has experience using this manifold and the quality or performance of it?

The area over the collector looks very weak. Looks similar to the old Honda manifolds from ssauto, xspower & obx that used to fall apart at the collector.

 

[kawboy]

How so?

 

[Imback]

The area over the collector does not look weak in my opinion. I would like to know the thickness of the tubing though. And most of these type of mani's are mig welded then given the the pulse tig to give it the tig welded look.

16ga 321 Stainless

Thin, but also 321 not 304.

I've run 16ga 321 stainless mani's in the past, no problems

I can't seem to locate any pics but a few years back a couple honda manifolds with similar mold formed collectors completely failed due to the incredible thin molded piping used at the collector.

There's a reason AMS just released their cast collector. The collector is not only one of the most important parts of a manifold to aide flow, but also reliability.

You'd think with time the companies would learn from their mistakes but in the end there really isn't any customer support from any of the larger overseas suppliers like ssauto, xs power & obx. They just have the products made, test fit them (sometimes) and mass produce them. They aren't really concerened with the reliability and to be honest who can blame them when you're paying $120? They trade off reliability for quantity. If people buy a crap manifold ssauto & the like will sell a crap manifold weather or not it's reliable

Disclaimer: This isn't a rant about the knock offs & all that nonsense, I'm just comparing quality. I'm not claiming ebay parts and no name china parts are bad quality since there's obviously many parts that work but exhaust manifolds almost always prove to fail due to the incredible heat & obvious poor design. I also don't think you should pay $600 more for a part due to reliability but there is almost always a better solution that costs somewhere between the two (FP cast manifold).

I can almost guarantee this design WILL fail on a heavier upgraded turbo within the first year if it doesn't within the first few months.

No data. . . Just opinion. Great entry to the exhaust housing! I like the detail to aerodynamics. The same detail I see in an fp manifold. Which is NOT equal length runners, btw. Though that doesn't seam to matter much. It seams that all the good manifolds have good collector designe with plenty of length of the runner direct as straight to the turbine inlet as possible. . . There's a scientific reason for that. But no one wants to hear about that. They want to hear about what works and what doesn't. So this manifold has specific attibutes of those that work.

In that vein, tubulars in general don't handle years of abuse (excessive timing retard, long tuning periods, etc.). The 2g manifold is proven to run 9s. But I wouldn't run one on a 9second build. I never get that arguement ???

16ga 321 Stainless

Thin, but also 321 not 304.

I've run 16ga 321 stainless mani's in the past, no problems

The piping is 16 gauge 321 but I will guarantee you the collector area is thinner. The same method of manufacturing is used when making any formed pipe such as the EVO 8 & 9 o2 housing.

321 is definitely a much improved material at high temperates in comparison to 304 but it's no god send and any collector that thin is destined to fail.

Now we're getting some good feedback and info

Mangina check your PM's

BTW, I was told OBX offers a lifetime warranty on this manifold against defects. I specifically inquired and was told it covers against cracking also. The only catch is your warranty card must be filled out and sent in to OBX within 30 days of purchase, otherwise you have no warranty.

I believe, as long as it holds together, which I have no doubt believing on a 16g (A holset/o2 housing external gate setup worries me), this manifold will outperform a DNP/DNP Style and perform just as good if not better then a FP Race, while also giving you that smooth tubular sound (That you commonly loose with a cast unequal length).

Still, any real world useage of this manifold is definetly requested.

It's really difficult to gauge performance by a few pictures but as Matt suggested above, one can only speculate how the manifold will perform by comparing it's characteristics against designs that have proven to work and make power.

I'm personally not a fan of the design & I think the interior of the collector is sloppy where the runners meet and the overall runner design isn't very conventional for a equal length runner with the sharp bends before the collector.

Hopefully someone has either had some experience with the manifold & can compare it to a more reliable solution such as a ported stocker or FP mani.

bringing back an old post. this was interesting to read now since it was well over a year ago has any one happen to try out the obx manifold?

 

[Black95TSIawd]

I bought this thing recently. It looked great and was welded/constructed beautifully. It was almost as heavy as the stock manifold. However, the angle of the turbine flange is off which puts the turbo closer to the water pipe. A 16g might fit, but not my 20g. Also, the holes for the turbo bolts, I bought studs instead, are too close together. I mean the studs fit through, but the turbo almost had to be shoved up and into it. You had to cut two exhaust manifold studs as they hit the runners and my o2 housing would not bolt onto my downpipe due to the wrong angle. I sent an email to the guy I bought it from on ebay and he said their jig is the same and they've sold 6 since. I guess my 20g didn't like this manifold, but I don't understand how my o2housing doesn't fit. I took it off and put my stock mani back on and all is well.

ps. The welding and construction looked great. BUT, they need a better jig.

Thats the one I bought.

 

[ryanx99GS]

I was lookin into grabbin one of these also

 

[JMiller]

Never mind.

 

[herms99gst]

Im also looking into one of these seeing as the price is right around what i want to spend for a t3 manifold. Ive read through the discussing and i, wondering if everyone has just tried out the mitsu flanged tubular and not the t3? And would it support the weight of a Holset h1e? This turbo weighs everybit of 27lbs, so would bracing be a issue? Idk i might just buy it and see what happens. Its this dnp or punishment racings t3 and by far this price is more appealing
