If you want even more ride height, you can loosen the triple clamp and slide the tubes down until they're flush with the top. You'll lose some of the quickness steering you get from the reduced trail (raising the rear reduces the trail), but raising the front even a little bit will increase your cornering clearance significantly.
Because your overall rear suspension travel does not change, you will still adjust the belt tension as per the manual. However, raising it up an inch will loosen the belt slightly, so you should have to re-tension it. That said, it's probably still within the correct range, especially if it was on the tighter side at the beginning.
Loud pipes don't save lives, they just piss off voters.
