OK....I have finally got some extra time on my hands and have decided to port a dsm exhaust manifold. Most of the guys that know me, know I port Evo intake and exhaust manifolds. Several of these cars are in the low 11's and 10's. This is the first dsm manifold.

My question is....There is a divider at the turbo flange, Does it play any roll? I am planning on cutting this out and knife edge everything inside. I got some new porting tools that allow me to go around corners. So I should be able to port all the runners 100%.

Let me know what you guys think.....
