dps 650 upgrades?

Im wondering what size tires i can run on my dps 650 with a RDC spacer kit, and what kind of tires i should run, im planning on doing mostly creating my own trails and also something good enough so if i do run into some mud or marshes i can easily keep my self out of trouble. also im wondering what kinds of exhausts are out there for my 650 i want something to give the bike a nicer sound but nothing extremely loud as my neighbours love to call the police for every little reason…. any advise or help would be greatly appreciated!!
