    hahaha, not really. just a log manifold. if i remember correctly, you're going to buy some of those old style headers they run at bonneville and reverse them, correct?

    Well thanks ! Did u happen to notice that the discharge to my turbo is the same size as your air inlet ?? Glad you mounted that thing so close to the motor ! I bet it would have SO much LAG ...
