How Good is the OEM Nismo Exhaust?

Not good, adds +/- 4WHP, if you trust the accuracy of the dyno.

The Nismo S-Tune actually adds HP, conveniently, I have one for sale

The Nismo exhaust flows better but not much better than the stock Nissan 370Z OEM exhaust the difference is only 4-5 whp on a dyno. The sound and tone difference is minimal too. Replace your whole exhaust system if you have the extra coin to do it. From the headers back or the test pipes back. Aftermarket exhausts will flow much better depending on their configuration and design. Exhaust parts for the Nissan 370Z are expensive comparing to other vehicles.
