That's what I figured. But single or twin scroll won't change the gate purpose TMK. Either way, they're there to prevent creep. Twin scroll is, in short, a way to distribute engine exhaust pulses. In this case, a twin scroll won't help as much because he has one long extension from the collector of the manifold to the turbo, so the exhaust gases are 'gathered' by the time they enter the turbo.
