These manifolds would be a pain in the *** for anyone wanting to install them to their GTM kit. Nothing would fit up correctly, and you would have to redo everything and buy new turbine housings.

If someone sent us the GTM manifolds, we could make bolt up replacements for them. Depending on how many people wanted them, and depending on what style, we could probably make a batch of them.

Things to consider:

More people (possible GB), brings costs down

Fabricated has less upfront investment and less initial time involved than cast, but has higher individual costs unless the volume is REALLY high, which it wouldnt be. Fabricated ones stay just as hard to make forever, where castings are easy as pie once the expensive tooling is built and refined.

Fabricated can be easily repaired by any welder if it ever cracked. Cast *can* be repaired, but nobody wants to do it or trusts it.

Cast is able to produce nicer smoother runners in tighter spaces than fabricated reasonably can. Fabricated can make very nice smooth runners and collectors but takes more space to do so.

We could also do a hybrid billet SS and fabricated manifold that would be SICK, but we would be looking at $$$.

If someone sends me the GTM manifolds, I can put the flange relationships into CAD and then we could consider options if you guys wanted.
