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

NissanParty · 06-04-2023, 03:23 PM

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.

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...
