I know I'm going to get a bunch of opinions but that is what I'm looking for. So as far as a pipe and air filter and rejetting goes for an 05 z400, What are your thoughts on the alba kit, and the fmf kit that alba sells?

I'v got an 03 Z400, I am runnin the full alba stainless and a K&N with no airbox lid.

works reall well for me.
