Welcome to the Forums, Marvin.
Ian-PT-GT's Stock Air Box Mod Guide:
1. Unscrew the air tube brace and pull it out from the air box.
2. Pull out the PCV tube located on the left side of the air box.
3. Pull up the entire air box; a little tilting would make it easier to be removed. this item is held by two rubber grommets in the bottom of the box. This is done like this because is the only way you can remove the battery.
4. Now that it is outside it is very easy to work with it, open the air box and remove the air filter. You will see the two silencers, one in the box cover (white) and the other one on the bottom of the box.
5. Remove the lower silencer. The screwdriver will help you here, insert the screwdriver between the silencer and the edge of the box right in front of the gap where the silencer holds the box apply pressure on the silencer and it will unclip in one side, turn around the unit and do the same on the other side. After this is done you can pull out the unit out of the box.
6. The top silencer removal is simple. Use the same screwdriver to jam it between the silencer and the corner of the air box in order to let the little plastic tab in the silencer to slide down without breaking.
7. Install the filter back, close the air box and install the air box in the reverse way that it was removed (steps 3,2,1)
The first photo shows the location of the pieces in Steps 1-2-3 above. The second pic shows the two silencers after being removed...
