Even if that was the reason, it seem to happen to high end aftermarket headers as often as not.

No mater, we are still looking at a great and worthwhile project that has solid potential.

Not much point in trying to scare us away from lower cost imports.
Well said!!
No point in scaremongering us away from cheaper options if they are checked and prove to be an option for some.

I think everyone was just saying "Buyer Beware". A lot of potential owners/buyers out there lurking in Pelican Land that have little or no experience in selecting the proper equipment.

There has been no study done to compare the frequency of turbo failures and the correlation to high or low end aftermarket headers that I am aware of. Any data points listed here stand alone.
The word "cheap" has many meanings. A product can have a cheap price or be expensive but made in a cheap manner. You all are aware of the infamous P-tax.
Anti-slag is just one of our design criteria. That you never have to learn about that the hard way is a design goal.
My headers were not developed as a cheap alternative and will not compete with the likes of OBX. The engineering goal was not volume sales but quality and performance at a reasonable price. Everything Ben and I produce is made in the USA. These products help employ Americans which is important to me, especially now. It is good if you have no problem with your Asian headers, 'cause if you do you're likely on your own. I'm a phone call away.

I do want to point out that my comments were not really aimed at how someone should (or shouldn't) select a header. My comments were more aimed at what I believe might be a false correlation between headers and turbo failures. My honest belief is that poor turbo builds are WAY more common than many people think. It is, without question, the most specialized component in the equation.

Headers or turbos, there's no substitute for quality, IMO. Customer service has to be factored in as well... and Rarly8 took my email after midnight on a weekend and turned out a product for me by 7:30am Monday morning... while building the very header discussed within this thread. There's no substitute for that type of service either.

Geez you make me laugh

Correct,had no problem with my asian headers apart from cosmetic damage when i stupidly bottomed them out and hey they are still holding up and supporting the good power my car developes..

Come on... i know for a fact i am not "on my own" with having success with these and similar ones,,scores of people have had success and we all know this!

As Werk-i says its "buyer beware" and inspect everything we purchase,expensive or cheap.

Your product will sell without the scaremongering... and i look forward to seeing the final results..

Thanks for the phone call offer.lol.
Hey i might use it for cosmetic reasons but not for that "scary" turbo failure.

Good luck and wish you the best with your header option!

I did not realize that Brian nor I were scare mongering? I thought we both were explaining the reasoning of Brians designs. Oh well

Thoughts do not translate well over the internet so I will reiterate.
I am sure there are many happy OBX customers, it's a numbers game like anything else. The difference is what happens to those that DO have problems. The number of phone calls and e-mails I get to help solve cheap header issues tells me that they have little or no support after the sale.
I'm not saying call me with your OBX problems, I'm saying that I stand behind my product and I am available to aid in any way if there is a question.

Bump.

What is the current ETA for production.

I would think but didn't see it expicitly stated that they would be applicable to 964/965 turbos.

The secondary pipe is being fixtured as we type. Once finished I will verify fitment and then start bending pipes.
Those of you who e-mailed me for introductory pricing will be notified as soon as the first sets come off the line. I am working on pricing right now which is directly tied to how much of my a$$ will be hung out bankrolling a large production run.
These headers will also be available for the 911. Ben is finishing the muffler extensions for those right now. Anyone for 1.75" equal length 911 headers with heat?
Yes the turbo system was also designed for the 965. I lost my test car as the owner sadly totaled it some weeks back. I have located another so fitment verification can now resume.

Here is a picture of the 911 prototype:

Believe me Brian if anybody gets my business for headers you are at the top of the list.

Beta Header Assembly

Got the first set of Beta/production headers back from Ben. Time for some testing.





First - installation. Did this from a complete noob point of view to see what problems might be encountered in the field. Just how much can you screw it up? Well what I found was it is not as easy as it looks (imagine that!) I have built in several areas of adjustment which it seems are a double edged sword. I purposely screwed around with the bends to mis-align them to see if it all fell back into place. It does but you have to work at it. These joints are a tight fit.
Long story short it took me an hour to install the system. I now know the best way to do it and will make up an installation sheet with pictures to be included with each set.

You can see in the following pictures that:
> The stock early oil tank is retained.
> The stock late oil line is retained.
> The waste gate is near its original location and the stock lines hook up.
> The valve cover can be removed with the waste gate in place.
> Stock height ground clearance is retained.

I am going to tweek the Y-assembly just a tad to make it easier to install then we will start production!!

Inventive wastegate circuit - interesting. Does the wastegate pipe have any support or does it sit on the secondary? I can imagine after a certain amount of time that the wastegate pipe would vibrate being so long (and heavy with that monstrosity of an OEM wastegate) and possibly crack a joint. On my Marco Manzie header, he cut a piece of a pipe and welded it to the secondary so it sat "in a cradle" where I hold it in place with a stainless hose clamp. Might not sound like it, but it works well and looks good.

Yes Don that is one of the tweeks on my list. Great idea about the cradle. I figured we would just weld the WG pipe to the secondary so it does not vibrate but a cradle would work better as it retains flexibility in that arm. This system is an accumulation of ideas like that, thank you!

Nice job Brian/Ben! I’m getting close to replacing my stock setup.
What does the final configuration look like with heat welded in?

The springs holding the collectors reminds me of my 2-stroke MotoX days, well proven method!

Thanks all -
Heater boxes are next and will be bolt-on to retro fit in the field and make for easy repair or replacement.
