Does anyone know the p/n for a stage 2 screaming eagle kit that I can have installed in my 06 streetbob?

 

The closest thing I see in the SE catalog is 29775-02B the 95ci kit with 203 cams. Although it's listed for up to 05 Dynas, I'm not sure specifically why it wouldn't work for you.
Another option if you're wanting to stick with HD stuff is to piece together the pistons/cylinders/cams etc separately from the SE catalog instead of what they call the Stage 2 kit. You probably want to go with the 204 cams instead of the 203s anyway.

If you already found what your looking for never mind but if you didnt here is a link to the air cleaner

Not sure there is one kit for that. Think you'd need the SE A/C kit plus some SE slip-ons plus some SE cams like the 204s and the fitting kit.
