When I had my 98" build done, I had true duals with V&H slip-ons. I bought a set of Thundercones to install after the build. My indy told me I would loose a lot of low end tq with the Thundercones. So I went with the 2 to 1 Thunderheader. For me, it was a good choice.

No, your collector in the TH is in the rear end. The PC's as you call them just restrict the air from moving from the heads. Bad idea to use both of them together.
Scrap the cones idea and just go wtih the TH.
