you haven't been listening very hard. being that there are only 3 manufacturers, searching for "header" would have given you all the info you needed. awr is race proven. racing mazda's is a modified mx-6 header, and ractive is brand new. no dyno's on the ractive. no dyno's on the racing mazda. dyno by equinox on the awr.
