I have heard its better to put a turbo on a single exhaust because it harnesses the power of the turbo moreso? anybody else heard that? right now I have a full 2.5 dual hks exhaust and am debating supercharging or perhaps putting on a turbo, anybody know if the supercharger would be more efficient with the dual exhaust or does it matter?

 

It depends on several things, how big is the turbo exhaust housing? Is it single? Is it twin? You want to size your exhaust to your turbo.
