I would like one as well. Please add me to the list. Thank you very much.

Hi @gonzopancho hope you're doing well - just wanted to see if you have any idea on a rough timeline, is it 0-6 months? 6-12 months? or greater than 1 year? I've got my name down on the list for a header, but have an issue with my current manifold and don't want to move too quickly if this thing is right around the corner. Thank you!!

@PabloCruise lets put me on the list. looking great

Hi @corcel , I am sorry for the delay in replying.
W/o speaking for @gonzopancho , I can say we are in the <6 month window. We learned a lot by fitting that first prototype.
I see you are in CA, are you looking to have someone install the header? Or would you be in the DIY category?
Last question - what is the issue w/ your current manifold? I am assuming you mean you have an issue w/ your exhaust manifold?

 

[peesalot]

comin up on 2 years, any production units expected ?

 

[CruisinGA]

I switched to 3FE manifolds on my 1.5F 13 years ago but I'd buy one of these just to have in the stash when they are ready!
(i guess that means add me to the list please )

Hi Pablo,

I’m in the DIY category - my manifold has a big leak, and since I’m going to be in there already, I’m planning to swap out my California thermoreactor manifold for a federal one or a header. Thank you!

Got it, thanks.
Where in CA are you?
What year is your 40?

I think I already have you on the list, let me check!

My timeline shows @gonzopancho got a sample from @65swb45 in March of '22, in April @Dianna was kind enough to loan us a cylinder head, and by May of '22 we saw pictures of the development of tooling for the rectangular primaries.

Fast forward to late Nov when we got 2 prototypes.

We noticed a few opportunities for better fitment and are expecting a v2 prototype soon!

I am not trying to be contrary, but I don't know where the 2 years comes from? This thread started in Oct of '21.

I hope that gives everyone a little more clarity on where we are.

My bad, I was going off post dates not actual production/r&d dates, on me for not reading thouroughly.

No worries at all!
I know it’s frustrating waiting for a final product.
We are pretty excited about this, but it is definitely taking some time.
I look forward to providing updates!
Thank you for asking.

 

[gonzopancho]

The issue is how to make them fit best across the years. The prototypes made by copying the Downey/Mark’s design were too close in places.

Update coming soon.

 

[brian]

Could you make a run of the original design while this new design is fine tuned?

 

[Hugh Heifer]

I am still in

Brian, it costs thousands of dollars to make a jig; you only want to make ONE. IIRC, it cost Jim $8000 for the jig I inherited 20 years ago.

 

[peesalot]

Mark, in real world use is there a benefit to this header vs. say using 3fe manifolds ?
Whats the cost range looking like for these new headers ?

 

[desmocruiser]

I just did that with a MAF 2 piece. Sexy.

Alright agreed, I am sold!

How do I contact and find the Wizard to weld up a nice connection to the rest of the exhaust or heck, just rebuild the whole thing header to exit?
