Hi everybody, I'm looking forward to change the stock cat with a sport-type cat so I need to know what are the inlet and outlet diameter measurements on my ncp13.

thank you!

It should be just under 2" iirc. The front pipe is double wall so you will have to put a few tack welds to secure the inner pipe to the outer prior to welding in the new cat. I do it all the time.
