Nothing wrong with trying to maximize your potential. I'd go with the H-pipe and a low restriction muffler
If you dont want 'popping', don't run glasspacks on true duals without a resonator.
If you install a balance pipe; you may want to think about not welding it in solid. I helped a friend R&R his 700r4 and we had to sawzall his homemade exhaust system...He was kinda grumpy about it.
