4 is where the bolts go in, it's what holds your headers on.
2 is the rubber grommet that holds a bolt that goes under the bike.
3 is your servo valve, the cables go up under the seat and are connected to a motor. At lower RPM's the servo valve closes and gives more torque. In higher rpm's it opens to allow more airflow.
1 see above
5 looks like the washer on number 2, and there's another one that comes in from the back side.
There are gaskets listed on the OEM diagram... part # 18291-MN4-920
I would pull the headers and see if the gaskets are all there. Couldn't hurt, but make sure you get the torque right putting them back on.
