I think if you took a ruler/set of calipers to it, you could figure it out. What are you trying to do/prove anyway?
 
collector size is outer diameter is 63.5mm but you would also have to minus the same differences due to the reducer as well.

You could technically make a 96spec downpipe by chopping off the EK4 collector, but the 2-1 section on the 96spec/B16B is smoother.
