I have a 2000 mustang V6 3.8L. I already have a K/N cold air intake and flowmaster duel exhaust. I am saving up to get a stage 2 clutch, ceramic headers, and a performance chip but i do not know which brands are better for each. What do you recommend. Also what else can I do to upgrade the performance besides and turbo or supercharger, besides those 2 ill do anything. Please, all opinions and suggestions will help.
