not about the wastegate issue but about the "flowing faster through a BIG oval than through 2 pipes, with an obstruction in the middle". If the total circumference of the two smaller pipes is more than the single oval pipe then the amount of restriction is less with the two pipes. Also, gas velocity is higher (and the pressure is lower) in a smaller diameter pipe so two of these small (remember total circumference) pipes should result in better scavenging. BTW, you have an interesting history with SAABs.
