Custom duals to y pipe

Still debating on where to connect the Y pipe at, Before or after my torque shaft Z bar, Pishta i found that article from Pete Hagenbush recommending to run the two pipes from the split manifolds 6 to 8 feet before connecting them to a Y pipe. Probably will try that out so how it works out for me keep you guys posted
there you go, they dont mention the length of the head pipes? Strange....

<edit>

"...Pete Hagenbush (sp?) was one of the engineers who helped develop the 2 barrel Super6. In an article in Allpar talking about the /6 he said splitting the exhaust in two, 1-2-3 and 4-5-6, running 2 pipes back about 6-8 feet, then re-joining them into a single exhaust out the back made a lot of power. He wanted dual exhaust on the Super6 but it was not done because of the cost..."
