I would get a set of Hooker Competition headers. They are good, and decently priced at about 165-180 depending where you get them from. Those are for the competition headers, not the supper competition. You really don't need the supper competition until you have 430+ hp. There not that much different from the regular competition headers other than pipe size and equal length.
