From what I can see, the exhaust manifold is shorter. Shorter distance between the exhaust port and the turbine means better response. This setup also makes for much shorter IC piping; shorter distance from the turbo outlet to the throttle body means better response. The intake is extremely short and also gets cold air; shorter pipe means less pressure drop before the compressor which reduces the pressure ratio you have to run to get the same absolute pressure in the intake manifold. Less pressure ratio/less boost means the air comes out of the turbo cooler leading to more power and also quicker response. Colder intake air also means quicker response and more power. The exhaust flow path out of the turbine housing is nice and straight followed by big gentle bends. This should have much less flow resistance compared to a stock location turbo with a much sharper 90 degree turn right after the turbine housing which increases back pressure and hurts power.
