I used a car manifold and the outlet sawed from a truck manifold. Cut as close to the manifold body as possible. The truck outlet fit the contour of the car manifold real nice. I used a divider plate in the center that blacked about 90%(this was info from an old time hotrodder, everyone has their own opinion about percent division for the best sound). I do not have any pics right now but I will try to post some in the next few days.
