Custom duals to y pipe

No carb heat....But the Dutra duals are like that, they just run 2 fronts (with a universal flange), or the cheaper system is a Dutra front and a DIY chopped rear.
Diymirage: "...i wonder if it would flow better if you bought a second manifold and cut the front of that one aswell, and installed it on the back 3 cylinders?..."
Wouldn't fit. The mount bosses are opposite on each side of carb.
