"As for the power gained with the Alpha header or the 1320 header, I believe that is really going to depend on what other mods have been done to your Slingshot. We will be running a test of the Alpha vs. the 1320 with our supercharger kit this Saturday to see if there is any difference and will post up that info when we get done. It is not going to be completely relavant to a naturally aspirated setup, but will show if there is any difference at the flows of the supercharger kit.
Hope that helps,"

Wow, thank you for your help Dave, i currently only have the Alpha CAI installed. Was looking at the DDM short shifter vs the Alpha short shifter, people seemed to love the DDM short throw, so that's what I am going to go with, along with the Headers and exhaust.
