Yeah. I figured so - just was wondering about whether new is still available. I probably should file all this under “if it ain’t broke don’t fix it”. The CT already sounds mild and not too offensive and adds a little bit of aggressiveness.
Thanks.
Keep in mind that factory exhaust is HEAVY.

Good point. I was out on a cruise tonight and the CT does sound like it was made for the car. I’m just OCD about OEM but I see that there are so many with aftermarket exhaust I’ll probably just leave it alone.
Crazy heavy. I finally got around to installing a Comptech exhaust on my NSX. I kept my factory exhaust and put in basement, what a workout carrying that thing down there.
I'm an OEM plus type of owner, I like JDM parts and some low key period correct mods. As long as they are reversible. The NSX is just so quiet, needed to wake it up.
NSX-R exhaust is louder and freer flowing. And it's OEM. 
Still heavy as F though.

I am not sure there was a specific NSX-R exhaust. In the parts catalog 18030-SL0-J00 is shown as the exhaust fitted to the NSX-R. It also is fitted to other E-NA1 chassis, however.NSX-R exhaust is louder and freer flowing. And it's OEM.

I recently ordered and received 18030-SL0-J00. I'll get it fitted up in a couple of weeks and see what the performance is like. It will be attached to Pride headers and Pride high-flow cats.
Honda may have conformed it to other models. Like the 95 NSX-T (JDM) uses it. I was just watching the NA1 NSX-R Best Motoring special and Uehara said that the exhaust was "improved" for the R when he was discussing power with Gan San. It looks like all NA1 "regular" NSXs used the A00 version of the muffler until Frame 130000-140001, which I think roughly corresponds to 1995-ish
The NA2 cars use different versions too.
"Regular" NSX NA2 - J71
Type-S/S-Zero - J70
NA2 NSX-R - J20
FWIW - here is a picture of 18030-SL0-J00 for the E-NA1 NSX-R which will be going on my car soon. Perhaps the internals are different than the A00 or other versions you listed. Maybe the J00 flows better. We do know that A00 required the oval tips which all North American versions received from 1991 - 1994. Beginning in 1995 the front bank inlet was changed to a 90 curve at the cat and the cats were modified accordingly.

That's so cool! I do believe the J00 has different internals and flows better. I feel like the 95+ cars have a slightly louder exhaust note compared to the battlestart galactica mufflers.
in agreement about oem. mine when purchased came with an after market exhaust and 2005 rims , but the sale included the orig rims and exhaust (yes heavy and sitting in storage) any other tasteful mods done to car I kept all original gem parts including the original leather skins when I put new leather skins on the seats, the led turn signals I kept the orig ones and modified the new set I purchased. the Williams radio I still have the oem working radio... just my quirkiness to hopefully have a complete oem car to a future owner if and when I decide to part with car not anytime soon , hopefully new owner will be happy to have those original parts.. I was also told by the tech at Acura dealership that when the y worked on my nc1 the parts that come from Acura for this vehicle are sealed similar to the way the bomb shelter food is stored, vacuum sealed and well preserved. his reasoning is so that these parts probably sitting on shelves for long time will still be viable long after they stop making parts ... he showed me when the parts arrived and it was impressive packaging
So glad I replaced my Pride exhaust with the NSX-R unit. Yes, it is heavier, however I am not chasing weight. What I really love is the lower decibel level when compared to the Pride. Nothing wrong with the Pride if you want a great sounding exhaust (especially at the upper end of the rev range), however I was looking for something less noticeable especially when you get on it.
From what I can tell the performance has not suffered and actually feels better. Maybe it is because I can drive it harder without people looking around wondering who the douche bag is with the loud exhaust.
This post reminds me that I would like to be that douchebag you are referencing….currently have a CT, wanting to get a TI Pride V2….

Life goals LOL. While I loved the sound on the track, it became too much driving around town. But I get that everyone is looking for something different. The Pride TI probably sounds as good as it looks.
“Other innovations beginning in 1995 included a new and lighter exhaust system and muffler configuration for greater efficiency and lower emissions, an OBD-II onboard diagnostic system, “improvements in the Traction Control System (TCS) and newly developed fuel injectors.
Hi, does the exhaust have prominent HONDA logos embossed on the sides etc? I'm registering an NSX in Singapore and the exhaust has to be from the factory (the car I'm importing has an aftermarket one which I need to replace). I want to make sure they will accept this exhaust as factory.
Something like this:
I’ll try and get a better picture, this is what I have. It looks similar to your picture. 
Had a quick look at the OEM exhaust hanging on my garage wall, it has the exact same lettering!
It does look like the exact same lettering even though it's partially obscured. Thanks!
Hello, sorry to burst everyone's bubble. The exhaust, 18030-SL0-J00 is the NSX-R exhaust; however, it's also not. It shares the same exhaust between 1995-1997 NSX models (even with the NSX-T). There is however, a different specific NSX-R exhaust, though I have not really heard any difference on sound from personal experience.
A00 model went from 1991-1994; then was changed to the J00 for the 92R, and further models until 1997. The only difference would really just be the tips.
