Realistically you're pretty much already running a single side exhaust, unless you're running true duals. I like the look of duals on a bagger as there needs to be some balance if going out the back. Never liked the single side rear.
For the side pipe, check this out:

They look sharp and aren't obnoxious. The only downside is you don't want to be the guy on the right as you'll get hit with exhaust in the face at every light. You want them pointed up, as if you have them angled down, it blows all the dirt off the street at whoever is next to, or behind you.
p.s. You can't have that in Kali anyway. Boo.
