370z Nismo stock exhaust = r-tune B0100-370CB ??
 

So I saw on z1 they have the Nismo r-tuned exhaust. There are videos of it, it sounds nice and loud.

That is NOT what my stock NISMO exhaust sounds like at all. Also it says it has "Nismo" etched into it or something, mine doesn't.

Is part number B0100-370CB the stock exhaust that comes with the Nismo 370z? Did I get shafted? I bought my car used, did the previous owner put the normal non-Nismo exhaust on or what? It is very quiet. And the exhaust tips aren't blue. What gives?

Edit: Is this a genuine r-tune exhaust? The tips are blue so I think they have been heat treated, but the way the tips are attached looks different than pictures of the r-tune exhaust on z1. https://www.ebay.com/itm/285291562795

I have an update, I took some pictures. I heard some people say the R-Tune exhaust is what comes stock on Nismo cars. Is that true or not? Here are pictures of my exhaust, it is definitely not the r-tune exhaust. The tips do say Nismo on them but it is a single muffler.

Also I saw this black stuff on my exhaust but it is not oil, some was wet and I touched it, it was just dirty water... runoff from somewhere drains there? Or is something screwed up? I thought it was the rear diff bushing at first. I don't know.

I was looking for a true dual exhaust system. I drove a new Nismo, and yes it was as quiet as mine was. I talked to the people at Nismo and they told me the R-Tune was different and it had he H pipe I wanted. I ordered one and had the dealer install it.

It is a huge difference than stock! It is louder but not obnoxiously so. It makes a beautiful sound. I love to put my foot in it. The sound makes it much more enjoyable to drive. It is quiet at cruise. And the tips do have NISMO on them.

Thanks!!! I would love it because I want to keep my car "stock", nismo aftermarket is close enough to stock for me!

Does the ebay link I posted look like a fake one? It looks slightly different than official pics of the r-tune exhaust I can find online.

I should have put this in the exhaust thread, dang it

You have the correct part number.
B0100-CB is the system I got.

The one on ebay looks different, I have determined that the seller is incorrect/misinformed.

Looks like I can get a genuine one for about $1400 new, I will think about it for a few days!

Nevermind, the one I saw for sale is from a defunct/non-functioning abandoned website. Well dang. If anyone knows of one for sale let me know.

Thats you differential main bushing failed. It has silicone gel inside the rubber isolator. Once the rubber cracks/tears, the fluid comes out. You can see it running down your diff as well.

Same thing happened on my G37 and on every car with this diff. Why did they use this bushing...
