SLP makes a good can, not too loud but definitely a better sound than stock. A buddy of mine has the same sled as you with a MBRP can and it sounds great, probably a little louder than a SLP but no annoying. Sno-Stuff also makes a good can called a rumble pack, they sound awesome too, however they are pretty loud and can be annoying if you're riding down the trail for a long time.
a buddy of mine has an SLP can on his 01 xc 800 and it sounds nice not too loud and I have a dynaport can on my 02 xc 800 and they both sound nice!!
