From what I have heard, SMSP has one of the best Header for Honda's. They are kinda pricey, don't know about compared to the BisiMoto, but I have heard nothing but good about them.

I have only used a HP Racing header, and since I never drove the car with a stock manifold, I can't really say anything about performance with it. And I can't really say anything the sound since my exhaust is cut off behind the drivers seat since its a race car.
