75mm / 83mm Turbine / 1.10 A/R ? Why does a stock manifold perform better than a significantly less restrictive long tube header?

If you're only looking for 500rwhp, a 70mm t4 flange turbo will do that easy. You can find one in the $600 price range. For a DD a T6 flange turbo probably isn't the best choice for most people. Especially with a stock converter.
If you end up wanting more turbo down the road, all you'd need was the turbo itself and a new downpipe/wg setup, maybe injectors.
If you can weld/fabricate or know somebody, then run a stock manifold. After looking at building/getting the merge built, I bought a Trick hotside kit.
I wouldn't run that p.o.s. stock converter at all. There are budget single disk converters that would be a MUCH better option.

For NA, a header is better cuz your just wanting to get the exhaust out and away as fast as you can. In a turbo, you want to keep the velocity and heat IN the pipe to help spool the turbo. A long tube header has a LOT more surface area with all the individual tubes that will dissipate heat and that reduces the energy/volume of exhaust hitting the turbo. That's why log/stock manifolds perform much better in turbo applications.
