This has been stated on a number of occasions throughout the years, but I don't ever recall seeing any conclusive proof to either confirm or deny it. I'm not saying it isn't true (though I have some doubt), but if anything, it would make more sense if the JDM version were 60mm OD like the vast majority of Japanese performance systems for the car.

USDM is 2.25" OD with several smaller "bottlenecks". This has been confirmed by many individuals (myself included).

probably the OD
ID:
usdm: 2.25
jdm: 2.36
jdm header collector is 2.5 guys. Same as the inlet for the jdm cat. But the rest of the system is 2.36 ID.

No, the ITR piping is about 2 inches longer than GSR piping.
The b-pipe is equivalent to the length of an LS b-pipe.
