G37 coupe Exhaust Pipe Diameter Reference for our EX35

[AWGD8]

I finally picked up a slightly used G37xS COUPE Y-PIPE , MIDPIPE and Muffler.

Here are the actual pipe diameter (actual hole not flange) for G37 coupe.

Y-PIPE:

Y-PIPE INLET (x2) : 1 5/8" or 1.625

Y-PIPE OUTLET (x1): 2 3/8" or 2.375

MidPIPE:

MidPIPE INLET (x1) : 2 3/8" or 2.375
MidPIPE OUTLET (X2): 2"

Muffler INLET (x2) : 2 5/16" or 2.313
(Part# 20100 JL01C)

Once I install the G coupe exhaust, I will measure the stock EX35 pipe diameter.

Thanks. Interested to see. I have been considering picking up the complete magnaflow system for the g, as it is all slip fit and I could easily cut to shorten as needed. Open to just using the stock g stuff if it will fit.
