K i've done a little bit of research on the matter based on the fact that I plan to go duals soon myself. I *think* depending on the company, not sure about Flowmaster, you might be able to buy the left (drivers) side muffler from the GT kit separately so you dont have to buy an additional passenger side one. The passenger side one should be the same for the v6 and GT kits.
There are some companies that make Y pipes that attach to your current Y pipe to go to your mufflers, as far as I know these work just fine. Have a local muffler shop fab you up a custom mid-pipe, and if you want to go H, ask them to do that too. Shouldn't cost more than $250 from what I hear.
