Never seen that done on a stock manifold before and as you say it will only work on the two outer cylinders.
Actually will not make any difference to the performance of the wastegate i would have thought. Once the desired boost pressure is reached the wastegate will still open in the same manner as it would if working off all ports.
Interesting though what they have done to that manifold especially with the thicknesser plate added.
The only thing i would do if i were you would be to port the wastegate apperture as it looks to be very restrictive, would also port the manifold aswell (as its obviously running a large turbo) and match it to the exhaust ports in the head.
Have you got a pic of the entire manifold?
