first off why ? is the question you ask yourself . if you have a fairly moded 5.0 ,you would still ask this question . If your dynoed at 350 hp then maybe . If not , don't give yourself headaces . cause you don't need any ( and we could go into this forever ) if headers are your cure ! unequal length , there are many , anymore than $160 ,your paying to much . and the ease of install
