new can am l570 upgrades

Just wondering what everyone suggests for upgrades to a base machine? I’ve already added the radiator splash guards, moose hand guards, and a home made plastic skid. What should be my next upgrade? Clutch kit? Exhaust? Do I need a tuner if I buy a slip in exhaust? What’s the best all around performance tire? I’d like something a tad more aggressive but not full blown tractor treads?
