If there is still any confusion, please see my thread for detailed photos showing the difference between the stock exhaust from a 350Z Nismo and the aftermarket S-Tune (technically the pictures show a Fujitsubo Legalis-R, which is 100% identical to the S-Tune other than the tips. The tips on the Fujitsubo are larger than those on the S-Tune).
It might have been installed on an '08, but it's not a Nissan system; regular Z, Nismo Z, or S-Tune. None of those systems have a double mid-pipe or two-inlet muffler. Can't say what it is, though.
Just to clarify all the info in this thread, the OEM system on a Nismo Z is essentially the same as on any other HR-engine 350Z - except the Nismo muffler has a stainless (semi-polished) outer shell and larger tips. The Nismo muffler will directly bolt up to any oem 350Z (or G35) mid-pipe.
The S-Tune system has a different Y-pipe and mid-pipe (larger diameter, and different shape), and a totally different muffler design. The S-Tune rear muffler will not directly bolt up to any other midpipe because its inlet is a larger diameter and it's curved differently. You can bolt an S-Tune mid-pipe to an HR Y-pipe, to use the S-Tune muffler, or you can fabricate an adapter to use an S-Tune muffler on a 350Z or Nismo Z mid-pipe, like this one:

Note the different, double-walled tips on the S-Tune. And, they're also slightly pval-shaped and tilted upwards:

Reading this thread, no one really seemed to emphasize the difference in sound each system produced. Having a 350Z Nismo, the oem exhaust that came with the car was rather dissapointing. The note was deeper, but quieter than the oem non-nismo 350Z. The typical 350Z note on the oem Nismo exhaust was muted IMO. I picked up an S-Tune exhaust and the difference in tone and loudness was night and day, in a good way. The tips on the S-Tune are a bit smaller than the oem Nismo, but nothing substantial. The S-Tune really made the non-nismo oem 350Z note more apparent and louder.
It might be the video, but the Fujistubo exhaust sounds quieter than the S-Tune. With the muffler internals different, I can't see the Fujitsubo and S-tune being the same.
Agreed the best-sounding of the 3 Nissan systems discussed here is by far the S-Tune. Not too loud, but it's deeper-toned and doesn't ever drone.
I'll disagree on the Fujitsubo sounding any different than the S-Tune, though. I've got the S-Tune on my '08, while a friend has the Fujitsubo on his '09 (roadster), and I (we) can't hear any difference.
Best thing about the Fujitsubo right now is that they can be had for a great price ($600 at some vendors), although that doesn't include a Y-pipe.
ok so look-wise how do u know if its a s-tune or stock nismo? i picked up a nismo exhaust..all i can say is the mid pipe is 3" into the muffler..its all stock..

There are so many threads w/pics here I'm not even sure why you're asking how to tell an S-Tune from the other two OEM systems. But quickly - the S-tune muffler is polished stainless steel and it has the double-walled tips (with the "NISMO" etchings), and the inlet pipe is shorter (it's just a 90-degree bend, while the OEM system muffler inlet is more of a J-shape). Finally, the S-Tune muffler also has the "WELDINA" manufacturer's tag tack-welded onto the muffler can.
So, same sound confirmed then. Are we talking quite a difference in volume?
Not a huge difference from stock, at idle or constant throttle, and no drone on the highway. Just a deeper tone, but the S-Tune is louder under when you're hard on the throttle. Law enforcement would likely think it's a stock exhaust.
Please see my thread for pics/vids regarding the OEM Nismo exhaust VS the Fujitsubo Legalis-R. The Fujitsubo Legalis-R is identical to the aftermarket Nismo S-Tune Exhaust, other than the exhaust tips. The S-Tune is the "American" relase of the exhaust. The Legalis-R is the Japanese-imported version. Outside of the tips, they are identical. The few pics above of the stock-looking y-pipe, mid-pipe and muffler are from a 370 Z.
Sorry, the mystery of OEM or S-Tune still baffles me. I've looked through so many threads and still not sure. I just want to be sure of what I have before selling it. Can you guys tell me if this is S-Tune or OEM Nismo? I think it's S-Tune but again I dont want to sell something falsely. It does have a Weldin plate on the muffler also.
