If a header manufacture wishes to copy my design and give me a royalty for each set produced, they are welcome to borrow them next winter for measuring and duplicating. Of course all my secrets are exposed here so I doubt that would happen.

But as for me making another set, not likely. I like to take on challenges and make things happen. I don't enjoy making the same thing twice, too many other things to enjoy taking on.

Finally back to where I started. The 4 into 1 merge collectors are complete.





I had to offset the location of the V bands as I could not get both of them side by side in the exhaust tunnel. I gave myself a little extra room as they will probably be a bit of pain to slide over the flanges as tight as they are to the sides and top of the tunnel so they are spaced a generous 2 1/4" away from each other.

In a strange way, that is kinda sexy. I guess that would oil the Tin Man's (Wizard of Oz) hinges really well

Looks like you have all the necessary measurements tooling and jigs ready to go. When are you starting production? I could be interested....

Tinmatt

Sorry, I only do one off projects. Once these are done it's off to new challenges.

Tinmatt

Back to square one.





The V bands ended up a little lower than I had hoped, even with the bottom of the seat rails. I needed the room up top to allow the clamp to slide over the flanges. In hindsight I should have gone with 2 bolt flanges but I hate gaskets and 2 3/4" V bands were only a few bucks more.

It doesn't look bulky at all under there. Cant see it being much cleaner or simpler.

SuperTom

don't see what the problem is

Sam Handwich

hmmmmm ........

Well, you definitely know more about this than me. Probably more than everyone else on here. Combined.
So if you say back to square one who am I to say otherwise.
Still, considering what you have shown us this far, we figured you could just show us a few more slick tricks.

Everyone's perception is a little different I took it as back to square one means he is going to start laying out the pipes.

Rob 02

Can you fabricate a double V flange sort of like a stockade?

Supercharged111

You won't have enough wiggle in the collector joints to be able to hang that mid pipe higher?

You're a metalworker, why not weld in a groove or slot into the tunnel plate that'll give you the room you need right at that section?

Me reading this thread:

What is a 180 header?
Ohh neat! Could it really sound that much better?
But that is a race motor, they all sound awesome.
Ohh I understand what he is doing, but wow I don't know.......

video of C5 with 180 headers plays.

Holy wow that sounds great! Please let this happen.

What is that jig for? Ohh he is starting at the heads and working back.
Ohh that is the collector! That might work!
Ohh no, that is a beautiful!
This thing is going to work!

Wow, I can't wait to hear it!!!!!!!!!

Awesome work, true engineering there.

Tinmatt

I might have a few more tricks up my sleeve, stay tuned.

Correct, working on the primaries right now.

Interesting idea. I may have to look into that if the V band clamps end up dragging.

There is some wiggle, more than I would like. But, the if I were to raise it any higher I wouldn't have room to get the V bands over the flanges.

Great minds think alike. I've been thinking of different ideas for that. One would be to make a new tunnel plate that was in a hat channel configuration. I worry it would not be as stiff as one in a single plane though. I will most likely do as you suggested and cut out a section and raise it. There is plenty of room between it and the torque tube at that location.

It is but it has a smallish cam and the same compression as the LS6. Hopefully I will get a very similar result with this set of 180 degree headers.


Once again, thanks for all the compliments and suggestions. And sorry for taking so long, hope the noise is worth the wait.

Supercharged111

So what you're saying is, wiggle room to fit v-bands is currently maxxed out? I was thinking since they're sandwiched in the jig, there may be more wiggle after they come out. Unless I'm forgetting something here.

Great job of fabrication so far!

I had to laugh at the last picture showing the weld table and the paper backed insulation.

v8srfun

That is not a issue with tig

nsogiba

Probably from grinding (most likely) or MIG

The Chev

All this talk about the insulation and no one mentioned the soda can bottom with the hose in it? I'm guessing that is from the shield gas.

Nice!
