I'm unaware of any brake upgrades for the raptor. I threw a set of $100 pads in the front and that helped a lot, with a good bleed job and good fluid. If you want to get radical, you can experiment with different size master cylinders to suit your needs

You can change to steel braided lines, change out the rotors and pads. Those are the easiest things. There are brembo kits available for the rear. You may be able to fit brembo calipers on the front; may require custom spindles.

Anyone has any input on this? I know the old YFZ450 calipers bolt into the raptor, but i don't see anyone selling any actual bigger/better calipers for it.

A rear Brembo brake kit is available from Cuervo Racing.

I'm not aware of anything for the front. HOWEVER, if you are very talented there is a fix. Look where the caliper rides on the rotor. It is about 1/4in from the outer edge. With a move in the caliper position to this edge it would be the same as installing bigger rotor kits. This can be accomplished in different ways. Fabricate different mounting plates or drill out the mounting holes and install offset bushings.

Another idea is to change the size of the master cylinders. It's been a long time since I've played with hydraulics, but IIRC, if you decrease the size of the master it increases the pressure to the wheel cylinders.
