Also too, the service guy said I would get 20 HP going with the stage 1 kit and this type of set up as far as 2 into 1 from stock everything and slip on Screamin Eagles. That seems A lot to me. If I had to guess I would say 8-10 HP. Anyone with this set up; what king of HP increase did you get?

I have the D&Ds with standard baffle plenty loud for me, love them.

I gained roughly 8HP with the AC and pipe upgrade. The rest came from the cam upgrade. I would take the bike to someone who knows how to tune it with one of the better FULL tuning devices. SEPST, TTS, PV. A lot of experienced tuners (not dealers) will tune 90% of your engine in closed loop using smaller bungs and then the remaining 10% in open loop using larger bungs if available so if you've got both that's a huge plus for you and your tuner.
