It is metric so you have to use aproximates.
The outlets from the catalysts are 60mm = 2.36" (I would use 2.25" to repair)
The above outlets have an ugly slash cut and then quickly neck down to 50mm = 1.97" (use 2.0" to repair).
The 2 pipes join to form the Y and the outlet is 60mm but quickly necks down to 55mm for the center resonator. I would replace with 2.5" but definitely keep the Y part that the factory makes by squeezing each 50mm pipe into a half moon shape to make up the 60mm outlet. This section is a torque maker.
