I'm sure there will be gains for the Nismo but it shouldn't be too significant. Some people in the forum dynoed a stock Z with the Nismo exhaust and got some gains but not as much as other aftermarket exhaust. And I'm assuming FI gains comes from smooth flow of the 2.5 inch pipe as a whole. Stock is 2 inch.
