Does anyone know what the factory exhaust size is? I thought I read it's 2" from the DPF back, but just want to make sure. Bonus points if you can include all sizes used from the turbo back :p

Got my delete pipe from CB Engineering, although they do not specify diameter on the website the pipe diameter was 3" from turbo back to the Y pipe where it meets your stock or "Cat Back" aftermarket pipes.

I just measured to see for myself. You will see in these pics the 3" side is my stock CAT that connected to Turbo. The 2" 5/8 side is where DPF pipe met with Y adapter...I wonder if it's smaller from crimping or factory spec. idk.

This is exactly the kind of info I was looking for! The middle section of the pipe where the 3 bolt flange is, does it appear to be 3" as well?
