Best exhaust - lightweight/quiet

[Rob5995]

Hi, All -
Aftermarket exhaust systems have lots of attributes. I am looking for the one that lives at the intersection of lightweight and quietness. Does anyone have any experience with this? SOS has one they like, the Endura Light, it weighs 25.8. I have no ideas what the stock exhaust weighs. Let me know what your experience is, thanks!

Endura Light drones and is fairly loud. Great sound tho.

These are older posts, but you may find them helpful:

The only two options that live at that intersection in my opinion are the Super Ti and the RFY GT V4 Titanium (Silent). Unfortunately, on the NSX lightweight usually means loud/drone. The above exhausts are really the only ones that upset that rule.

I have an SoS endura lite and it isn’t drone-y IMO. I’m pretty noise sensitive and it’s quiet ish when it’s not under load. I really really like it FWIW. Def not as cool or light as a Ti exhaust, but a solid choice imo

RFY GT exhaust 4.1 silent version. Get the Titanium version (it's full Ti) for extreme light weight. No drone, and it delivers on the silent promise (it's much quieter than my former Toda catback).

It's interesting how different people define "drone" LOL. Exhausts are so tough to describe online that way and I usually recommend people actually listen to one in real life. One man's drone is another's glorious tone!

Are you still running stock cats? I’m leaning towards this exhaust but even with the little amount of sound clips on youtube its hard to tell. The SoS description claims they reduced the drone so not sure if they ever revised the original design or its still the same

The Endura Light definitely is not as bad in the drone department as the Taitec GT-106 upon which it is based. It also has a really nice sound. But, I find it beehive - y and boomy around 2,500 rpm. My 2 cents.

If you're looking new, then Fuji Super Ti is probably the intersection of light / quiet you want (at the expense of tone).

If you're okay with searching for a used exhaust and flexible / open on budget, ARC Ti. The ARC muffler is huge - still has a nice tone to it but it's definitely pretty quiet.

@Honcho -
Thank you for the very comprehensive analysis and review of the Fujitsubo Super Ti. Based on all the information you have compiled, I am totally down for getting one. I have put in a bit of time sourcing the part, and it seems like no one has any stock - they seem to be only made to order. Options Auto said they could get one to my door in three months. Sounds great to me - heck, it's winter! Evasive Motorsports said it'll be four months. I am emailing a few other places like Nengun, and couldn't figure out the Japanese website for Hirano Tire.

It has SoS high flow cats and is supercharged. Here are a couple endura lite videos that showcase the sound inside the car under load. It doesn’t show any cruising load sounds, but really, it’s not bad. I can’t ever remember thinking that it was annoying. I bought the exhaust new in 2020. Everyone who rides in the car comments on how good it sounds

If you want to order from Hirano Tire, you need to reach out to Yossy at OOParts, Intl. He was my JDM contact for ordering from there, but these days you get just about as good of a deal using Blackhawk Japan.
