I have a '98 WS6 with cam, headers, and off-road Y-Pipes. My cam installer totally removed my EGR. What is the advantage with removing the EGR?

cleaning up the engine bay is probably the best argument for removing it. The end of the egr tube does stick down into the air stream so there's a tiny bit of help there. Horsepower wise the gains are very very small.

did you get tuned afterwards? There's an egr adder table that needs to be zero'd out......if not you'll get tip in knock under certain circumstances and it'll pull timing.

Pull timing? I've noticed no knock, but yes, under certain circumstances I have experienced timing loss. I have electric cutouts and there were two occasions where I did a hard roll-on in 2nd gear with cutouts open and acceleration was way less than expected.
I'm currently awaiting price quotes from a local performance shop on a clutch install and dyno tune. Should have quotes by tomorrow Noon.
