Swap 750-1100 exhaust:Same flow rate?

[buffalobill]

I'm swapping a 1127 into a 750.
I just bought an OEM Suzuki Katana 1100 exhaust system complete, very good shape for only $25.
Anyway I was comparing that to my 750 exhaust system and, by golly the muffler outlet dia. are exactly the same.
Leads me to wonder if they have the same flow rate?

I used the full Yosh exhaust that came with my 750 . Had to modify it a bit for clearance purposes , but no complaints ....

Interesting, who knows what the flow rates are outside the R & D dept.
It makes business sense to use the same muffler everywhere, and adjust the cam/carb intake tuning to suit.
But I dunno what they did.
