so now I can verify that all measurings concerning Yoshimura exhaust system is that 250 and 300 is completely IDENTICAL (but the routing of course)
After working with parts of it, what is left to be mentioned is that for every number Rassie is providing above, one must keep in mind a -3mm of inside diameter...
thank you Rassie for your quick response...
