I saw this on eBay and they said it is a Nismo r-tuned exhaust. But when I compare it to pictures elsewhere there are a few differences, mainly in the exhaust tips. They are blued and look like they are attached differently. I don't see a clamp on them.
They could have used a torch to blue the metal but I am not sure about the rest. I don't want to buy a fake one. I did ask the seller but they have not answered yet. They sell a lot of stuff so they may not know for sure.
