I thought it was a 2.25" system, but I measured the outer circumference which was 6". Now, my maths isnt brilliant but is diameter circumference/pi? If so that makes the diameter about 2"?
Is that the bore size?

that's small if that's the case, 6" circumference = 1.91" diameter (bore)
you'd be looking at an outer circumference of around 7" for a 2.25" system
