So I've been thinking about going out to one of the many fabricators in my area and since i Live in Vegas theres a good few of them. Since theres been no update in the quest for a quality made header for the aveo I figured id go to some shops and see how much theyd charge to make one up.
I pretty much just need to know what the basic specifications would be for a proper peformance header. Any and all help would be appreciated.
