This clamp mounts to the rubber hanger in the center of the exhaust and supports your center pipe by the rear bulkhead.
There is two different sizes depending on your exhaust - the one for the 948/1098CGs fits a 1.25" exhaust, while the 1098CC/1275 one fits a 1.5" exhaust.
You can get the rubber mount that connects to this clamp here.
