Third, what you have built yourself is a fine set of Crossover headers and you are right on the money. Those could dump anywhere and yours look spot on. That style never had the cool sound of the firing order 180 degree style but I always thought they sounded better than those weed-burner zoomies. Not only that, they are a whole lot easier to mount than 180's on the 1:1 or model car. Keep building, It's looking cool.
