FS: 370 Nismo Exhaust

Lemers

Looks like we have some people that know the difference between the two NISMO exhuasts. Which one is better? The S-tune or the OEM off the NISMO car? What are the gains over stock on each?

I guess S-tune has somewhat better in performance Just seeing the appearance, it tells so

SE

To my knowledge no one has really dynoed with the two different variations to get a really good idea of what the power gains are with each, so this is just my opinion:

The stock Nismo Z exhaust is a H/X pipe design...almost a true dual design. Typically these are good for low/mid range torque and power gains.

The Nismo S-tune variation follows the stock Y-pipe design with bigger piping and a different muffler. There are better alternatives to this.

Since we're talking actual USABLE power, I would say that the stock Nismo Z is definitely better than the S-tune exhaust due to the differences in pipe design.
