Get the cardboard tube from a toilet roll, measure the diameter then cut it at an angle you will see that the measurement along the angle is much greater, but the tube is still the same size!!! The toilet roll would still fit over it!!! End of lesson.

You are not taking a true measurement, it is cut at an angle the sharper the angle the longer it will appear top be, if it was cut square across it would be and is 64mm dia! 50 years in engineering, trust me!!
so a 64mm exhaust will fit?
so far ive tried a 64mm exhaust and a 70 mm exhaust both are too small
