Sbp exhaust

Does anyone know the power band range of the sbp exhaust? And with this type exhaust is it like no power until your on the pipe? I have a bbr stage 4 engine stock exhaust, waiting on a offset intake to mount the hp carb. I cleaned up all the ports, and gaskets and deck the jug for good squish. But don’t want to raise ports for rpm and lose engine life. The bike runs good. I have a long steep hill at my house. It pulls this and I can maintain 25 mph up it.
