OEM exhaust differences from year to year?

[NYCNSX]

I have an OEM exhaust and a set of OEM headers that I acquired years ago, and I would like to confirm what year NSX they actually fit. The tips look like the 95-01 exhaust tips. How can I tell the difference between 95-96 exhaust/headers and 97-01 headers/exhaust?

Thanks!
Jeff

The easy part is the manifolds the NA2 have tubular individual headers...the NA1 suffered with the yugo 3 into 1 collectors....The exhausts are the same from the can to the tips,,,,,

Great image, thanks for posting. So the exhausts are interchangeable between 94-01, and there is no difference fitment or flow wise provided the adapters on the 95-96 are present right?

 

[docjohn]

correct

 

[NYCNSX]

correct

Thanks, and to confirm the headers I have pictured are NA1 headers right?
Also are the heat shields interchangeable on the NA1 and NA2 headers?

 

[docjohn]

NA1.....I don't think those shields will work.....but I am not 100% on that

There is some unclear info here. By the looks of the pictures, the OEM manifolds and exhaust are off a 95-96. I’m 110% sure of this.

97-99 and 01-05 tubular headers are slightly different in the rear bank header. The collector is short about 20mm and that length is added to turn rear bank catalytic converter.

01-05 have the LEV cats so the cats are no equal lengths like the 95-99 cats. In my experience the 97-99 OEM exhaust and 00-01 OEM exhaust both have the slant tips but the collectors won’t line up so not interchangeable.
