On the N1 Dual, it's 2.5" I believe. I have the N1 single and it's 3". One of my friends has the dual, and it's 2.5". All you have to do, is to go the auto parts store (NAPA, Auto Zone, etc.) and tell them that you need the gasket for your car and then you can trim the inside of the gasket a bit to fit your piping size. That my friend, is your best bet.
