Although there are a few belly pans out there, they all basically fit the same way, but there are a few things that you'll need to consider.
You will need to mod the bottoms of your panels to fit this, or get some other panels.
But all bellypans are not the same, it depends if its OE from a 996R / 998S etc, but its more likely to be a aftermarket one.
Although some bellypans are actually mounted on the bike, most just hang off of the bottom of the side panels. The mounted ones can be a real pain to fit as you have to have the right brackets etc.
All of the belly pans I've had have always just been mounted to the bottom of the side panels, through the use of some DZUS fasteners etc...
Also, make sure that the belly pan will allow you to use a sidestand etc...
