Simas toilet flush pipe - 2 inches reducing to 1 3/4 inches

[AP77]

I am trying to fix a leaking Simas toilet, I think the flush pipe has been cut too short at the pan end.

I am struggling to find a replacement flush pipe. The existing pipe is 2 inches diameter at the cistern end and 1 3/4 inches at the pan end which seems to be rather uncommon.

I have tried the usual outlets so far but no luck so far. Anyone know where I can get one please? I assume the existing pipe is in fact the correct diameters as it has been in place since the house was built around 12 years ago.....probably been leaking a while though given the mess behind the boxing in/tiles!

Many thanks.

Those things are a pain, best if you can find (which isn't difficult) the proper thing.

Flush pipes for 2" outlets, commonly found on on concealed cisterns, are definately a thing

Thanks, yes, I can find a flush pipe with a 2 inch outlet from the cistern, but not with a 1 3/4 inch opposite end. Closest I can find is 2 inch reducing to 1 1/2 inches. Any ideas where I can get one? The toilet is made by SImas which I believe is made in Italy.
