Cheap manifolds cut corners on flange flatness and collector geometry. You feel it in boost response and you'll see it in cracks within a season. The 6Boost unit is designed around the GTX28 small flange — the flow path is deliberate, not approximate. If your 3RZ is going to see real heat cycles, this is the spend that pays for itself.
