It will be OK, no reason not to be.

Btw. this is a school example how should good trubo exhaust manifold built. It's made of a 316 stainless steel 3 mm wall thick, TIG, one pass full penetration welds.

Collector:

A perfectly angled runners..

so every runner "hits" center of the turbine housing..

WG port below merging point, so all ports can discharge evenly..

A 12mm thick ported flange, cutted to let some thermal expanding without bending..

With heim joint supports (can see on previous posts), it should be very crack resistant :).

And yes, we can manufacture more of these :D. Actually, one more is in a building process, the only difference will be in the turbo flange, a T3 one.

WOW Tom, thats beautiful, soo the one for sale will it be just the manifold? or is it going to have the extra long wastegate section?

The 2nd one is for our Aussie member Matthew (arrtchiu). He will get a manifold with ext. WG port, supporting brackets and heat shield for a $1500. It's not cheap but it's built almost without a compromise.

Of course, we can do internally gated manifolds too :).
