i already bought the k&n jet kit and pod filter, i guess its going to be a stage 3 kit im going to install.  i have a few questions if anyone can answer them that would be cool.
1. do i need full sport exhuast to have a stage 3?
2. is it safe to have a stage 3 kit?

nope dont need the full exhaust you will just be jetting it leaner than if you did have a V&H or simular.

Stage 3 kit is as safe as changing your own oil...

hahahahahah  
you learn by doing, i guess
oh man do i feel stupid

how many people run a stage 3 in there bikes?

Most people are cheap and just buy the jets. Also a bit more tested I dunno many with the dynojet kit that have posted thier specs for it yet.
