Are these new?, OBX headers Options

I've just got a funny feeling. The don't even have them on the OBX website. They look a lot like the old Kerry Hunter design, but I've never seen them before. (IMG:style_emoticons/default/confused24.gif)

I have never seen or heard about these.

[jsayre914]

never heard of it but seems they been making them for every vehicle

That is very inexpensive, I wonder if they are any good or how well they fit.

They are known for making the worst quality parts known to man...

Their metal is far superior than standard and their welds crack.


That being said, someone try it! (IMG:style_emoticons/default/smile.gif)

The tube shape looks literally identical to my Kerry Hunter header. I wonder if lifetime manufacturer defects covers cracked welds.. It sure does look pretty though, but not pretty enough to be a POS worth $250 if the welds crack and it doesn't fit....

Obx makes a helical lsd for a lot of trannys and the ones for the suby tranny has worked for a few years just fine on the nasioc site. Also I have a set of ss wrx suby headers from ebay but I don't know for sure if they are obx but they were cheap and they are at least as good as other more expensive brand headers for the suby that I've seen. They were not equal length though. I cut them up and shortened them for one of my projects.

[BMXerror]

Yes. Well, we have to be careful of the typical Porsche car enthusiast's mindset that more expensive is better, and cheaper is crap. I've studied a bit of manufacturing engineering as a side point to my job, and if OBX does this all the time, they may have all the tooling they need on hand to produce a quality product inexpensively. Chris Foley (for example) makes an awesome product, but I'm sure most of the expense comes from the fact that his headers are all hand built, one-off units. For $250 it may be worth getting a set just to try out.

If they had been around 2 or 3 years ago when I bought my EuroRace headers, I would have bought these instead. its hard to argue with $250, unless they are total crap and fall apart on install.

Someone needs to buy them and try them. the KH header was fairly well regarded - similarly to the Eurorace.

Now that is wild... I love the idea!

This isn't a system for any particular application. It can go into any TIV powered vehicle and allows dozens of variations in exhaust system design to be compared back to back, time and time again.

We can do a 4-1 or a 4-2-1 arrangement and can then do either as a step header or conventional arrangement either on the engine dyno or chassis dyno and then gain data from real time street application as well.

We can use 1-5/8, 1-3/4, 1-7/8 or even larger primaries and secondarys and changes can be made in a matter of minutes that have in the past taken weeks to compare. When the ptimum arrangement is found for the intended RPM range and peak power output, then a prototype with those characteristics can be easily built to fit the vehicle for future production.

This system and the others we have devised like it are tools. Tools developed for ass kicking.

It's a Mr. Potato Head for a 914. Looks fun!

THAT LOOKS F'N cool!

if by some chance the metal is so mild that it rusts very quickly(which I doubt) then if could probably be repaired cheaply by a muffler shop and still come out a great value for someone who wanted a "street header"

[turnaround89]

whats the difference between a 1.7 exhaust and a 2.0, are they interchangeable, because im kind of interested in this but don't have a 2.0

No, sorry, EMPI won that prize so many times it was retired years ago.

304 stainless could have some points of minor oxidization but it wouldn't hurt anything. And not just any muffler shop could weld 304, but with the price of stainless these days that price is RIDICULOUSLY cheap. It won't stay shiny like that, but I'd say the only two risks are cracked welds and poor fit. If you can deal with those I'd say jump on it.

wasn't that award even named the EMPI? small oval globe looking thing (IMG:style_emoticons/default/wink.gif)

[Katmanken]

That's slick Jake....

With that setup, you can tune the exhaust header lengths to look for the optimum length for a particular combo of engine parts, and you can check for optimal exhaust routing in a particular chassis before you go to rigid pipes.

I'm still looking for the slide trombone fittings to vary the pulse lengths. With a coupla slides, you won't have to keep cutting the flex pipes to look for an optimum length.

Only problem I see with something like that is: the more variables you have, the more combos you have to try to get meaningful data to identify the optimum setup.

More chinese ebay parts.....

If you like doing it twice, go ahead.

I can show you photos of a perfect looking used cast iron turbo manifold over 1/4" thick that manages to warp every 8 thousand miles, even when all 12 nuts are torqued even with nordloc stainless hardware.

That is cast iron 1/4" thick. Good luck with this super thin material. I bet it is schedule 0.

Run! away from OBX!!! stay as faar away as you can from these headers
