Tri-Y Headers for torque?

Pete had tri-y's on his willys?

I like home brewed solutions... What would happen if the center two cylinders were connected, numbers 2&4, and then1&6, so there are 3 sets of 2 cylinders.. and each is connected.. then the three collectors merge into one...?
You're trying to maintain a wide power band, and good from down low, right?
So the big thing will be velocity out of the exhaust ports. The least cheats and the smoothest bends. When the tubes start to joint, try not to go bigger than needed.
