i think the exhaust tips are the same as the Q60 red sport
They may well look and be the same, I'm more interested in what is just before them.
I can't possibly believe that the exhaust configuration in the photograph (ie no real muffler) would pass any possible noise test without some sort of a valve
Hopefully we will get a photo showing inside of the exhaust tips, although I'm not holding my breath as I cant see any signs of one

The VR30's sound is very docile on the Q cars. This muffler setup may very well be factory to give the Z a bit more aggressive, sporty sound.

The use of Tenneco is a departure from the Calsonic-sourced (or HKS for the Nismo trims) factory muffler sections seen on the more recent 370Zs. It's possible this is for the pre-production cars only, or this could be something entirely (the overall exhaust setup) to eek out a bit more juice from the factory to put the Z a step above the Q cars in HP ratings.

...and hopefully a step above the zupr4 too. nissan has such a great chance to deliver a knockout punch, i sure hope they take their best shot!

why not?? the zupr4 passed its sound test with all kinds of pops, gurgles and fart noises...

If I had to choose I'd rather the exhaust generated a better sound rather than an additional 5 hp, on a car this powerful that few hp is never going to be noticed except on drag strip timing slips. IMO 400 hp is more than enough for the street, I would have preferred 350 with 300 lbs of lard removed from the chassis....

I wonder how Nissan addressed weight distribution. From the looks of this picture the performance trim will not only not have that big heavy muffler but omit the spare tire most likely and then coupled with all the extra weight up front.

You reckon we will get a spare tire….very few cars come with them these days

You might be right... on the spec sheet it only states Tire repair kit as Standard. I've been rolling without a spare for a long time because my car originally came with RFT's and no spare, so I didn't even really think about it.

Do y'all have noise regulations in Oz?
Usually it's the EU with strict regulations, since the Z won't be sold in EU I reckon Nissan can make the Z more vocal.

Nissan already officially stated the power for both trims. Exactly the same as the RS Q's.

Yeah we do, the limit is supposed to be 90 decibels ….but there are plenty that get away with more.
Surprising that y'all have those regulations. My Australian friends used to tell me about all of the epic Australian market vehicles, I think Commodore, Falcon, Utes, mostly rwd with cool engines.... I guess times have changed

The new exhaust design appears to be some kind of helmholtz resonater / sound canceling design. The length of the "H" connection between the two exhaust ports is purposeful to eliminate unwanted frequencies in a certain band. LOTS of thoughts go into that and this exhaust looks much lighter than prior models.

Interesting yet i see way to many similarities between this and the Z34 version. Nothing wrong with just making incremental improvements to a design that made a LOT of us happy over the year.
