I'm going to be stretching the collector length out at least 2 inches if i can help it as well to further enhance the low end without going far enough to kill the top end. I know the bends are more exaggerated than the F.I. but i don't expect them to make as much power either. I'm trying to make the Injen cold air intake of the header market. It won't work as well but at least it will work.
