Diamond Perf.............answer to the inside diameter?

I'm sure it's me being vague with my questions. Inside diameter of the 4 pipes within the manifold.

So why are these used on other 1000hp supercharged racing engines with great results?

Actually, there is someone on OSO that has big blower motors and running our exhaust. He says they work great.
