I am pretty sure this is what the stage 1 intake looks like with two smaller cones, and
seems smaller diameter piping (edit: looking closer the piping diameter looks the same). Sounds like you currently have one so you can confirm if I am right. Looks like this
Stage 1.5 and 2 look like this. the intake runs straight the supercharger. (also check out the rest of that album

looking at the photos of the stage 1 reminds me that the stage 1.5 & 2 vents the bypass valve to atmosphere as well. not sure what that does for power.
