hi
i just bought a used NISMO s-tuned cat back system that came with Y-pipe, mid-pipe, and muffler. I see NISMO logo on the muffler, but is there any way that you can tell if Y-pipe and mid-pipe are Genuine since there is no mark on them. Should I bring them to the Nissan dealership to ask?

welcome any replies and comments

 

idk. But to be honest if u have a diff y pipe instead of Nismos ur better off

 

well they look the same when i saw on the website
but the thing is there is no nismo logo or something like that on the y-pipe and mid-pipe

 

Aren't Nismo S' made by Fujitsubo? If so take a look at a Legalis-R's Y-pipe and maybe that can help you confirm whether its authentic or not.

 

There used to be subtle differences (i.e., slightly different flex joints, quality of welds, slight design differences, etc) between the first replicas and the Nismo y-pipes, but now they're pretty much the same.

Honestly, with exhausts (and most non-moving parts), it doesn't matter if you have replica or authentic as they will yield the same exact gains (any difference is either negligible or within margin of error). What you need to be concerned about is quality of welds and fitment.

 

I had a Nismo on my car before. There is no marks or logo's on them.

 

I found laser-inscribed part numbers on them
thank you

 

post a pic, i can tell if it's nismo or not. especially the y pipe. it has a diff color/look/feel to it.

 

come to think of it.. my Fuji Y-pipe didnt come with any markings either.

 

i will post them when i got to my home
