Well there is something amiss.
You can clearly see from the turbine positions on the S58 pic I attached, that there isn't much difference in length to address to achieve an equal length system.
The airborne pic shows a big diversion by crossing one pipe over the gearbox, adding much more than the turbo spacing difference.
All the data given in this thread cannot all be true.
