I have a hayabusa 04 model. I put 2 slip-on scorpions on an the bike won't
idle properly it speeds up and down. It also pops back in the air box. What can I do to fix this problem?

I have the same problem on my 04 GSX-R600. I bolted on a D&D and immediately noticed the lopey idle. I figured it was a combo of less back pressure (you can see right through that thing, just like the old cherry-bomb mufflers!) and needing to be remapped. I have a power commander on the way.
