ok maybe this is an increditbly stupid question but here it goes. What is the difference between the differ Nismo exhausts ( Weldina, JDM, S-tune,Fujitsubo)?
S-tune is the exhaust everyone runs on the forums here, correct?
thanks for any direction. Is the Fujitsubo exhaust really superior in build quality?

The real NISMO exhaust is a cat-back system. You get everything needed from the catalytic converters back.


Items sold under other names (such as Weldina) are often just the muffler.

 

Then is that the same thing as far as a Fujitsubo exhaust system? Is it the same as Nismo or just a muffler(not a catback)? thanks again for any help.

 

As far as I've been told the Weldina is the same as the S-tune exhaust. Just made by a different company for Nissan.

 

a much better question would be the difference in piping diameters.

 

Is there a difference? Does anyone actually have one of these variations of exhaust systems?

 

I am not certain. You would have to show me a photo with description.

 

my nismo cat-back has Weldina on a plate on the muffler.

 

Same here. AFAIK, NISMO = S-tune = Weldina and Fujutsubo is a different make that is just nearly identical to the Nismo system.
