3 inch maybe? are you talking about a full blown race car? or a street/drag spec car? and why?

....ummm 3" that is one HUGE manifold...

I would imagine the interior circumference is around 1 inch and 1 1/2.

if you have a manifold measure the diameter of the exhaust ports on the motor. Those pipes are pretty close to that size.

Just shoot the company an email and they will know. My guess is around 1.25".
