Most bullet cats are about 4" diameter, so if your pipes are 3" then in a perfect world you'd lose 1/2" of ground clearance. Now if you don't currently have about 5/8" of clearance above the 3" pipe where the cat/s will be located then you'll either need to clearance the undercarriage for more room, or adjust the pipe/s lower resulting in additional lose in ground clearance. The clearance issue will most likely be on the drivers side.

FYI, with short section of thick metal plumbing pipe 3-5" OD and a jack you can clearance the undercarriage, by very slowly jacking the pipe up against the body multiple times while watching, and listening to the progress.
