Manifold questions

[RIPSTI]

Well ive been looking at you're manifolds and have been having some questions. What are the primary sizes? they look like 1.75'' is that true and is the manifold truelly equal length, any chances of cracking or of any nature? And where is the wastegate flange? thanks guys

Primarys are 1 1/2" ID.
The manifold isnt exactly equal length but its close.
We havnt cracked a manifold yet.
We run our wastegates off of the O2 Housings.
