Diameter exhaust clamp XJ900S Diversion

[Nickdylan92]

Hi Guys,

Normally I would go and measure this for myself but it's not my bike and I have to order exhaust clamps.

So my question is:
Can anyone tell me the diameter of the exhaustclamps of the downpipes to the collector. And the clamp dimeter which holds the muffler to the pipe coming from the collector.

Thanks in advance
