We'll see I will have it on the dyno before too long and thats the same build I have done. The Gen V Manifold help in a big way through the mid range. I picked up 30ftlbs through the middle of the power band so I am interested to see how these headers and catback compare to the American Racing Headers I had on before.
I will dyno this setup and the only thing left to do will be porting the stock heads.
