2 HONDA NSXs: The Lion's Roar Duel

In this video, we pit two aftermarket exhausts for the Honda NSX against each other: the Science of Speed (SOS) from the USA and the Racing Yamamoto exhaust from Japan. It's a showdown of American engineering versus Japanese craftsmanship, and both systems roar like lions! Watch the video to hear them in action and decide which sound you prefer. Don't miss it!

Why not sound sample under load?

[@DRBLUESNYC]

Great suggestion. We will defintively do that next. Thank you fro the feedback and the suggestion. ANy other suggestions for this video? Best regards and drive safely!

[@TBoneSan]

@@DRBLUESNYC Otherwise great! Keep up the good work

[@fredericberthou]

La première est tellement meilleure 👌🥰

Taitec GT LIGHTWEIGHT w/o cats and headers is also frightening

[@jdmnuggets]

Love the idea of this video guys, but ya really missed the mark lol. Call this ver 1.0? Can we get cold and warm start in the open aswell as a parking garage and more importantly some drive by towards and away from the camera with a mix of some deceleration? You have a unique opportunity to film two nsx 😮. I have a jdm 1990 na1 nsx with a full texas pride v2 exhuast, headers, test pipes and muffler. The sound was so rowdy i had to install high flow cats to cut down the rasp, it now sounds freaking amazing. Much love from new Zealand

Dude - that is GREAT idea! Will do!!!

You need rolling shots and fly by shots at full acceleration. Idle sound is just one small parameter of exhaust sound. You also need interior shot going at city speeds (50km/h) in 3rd or 4th to see if there's any unwanted low frequency resonance ("boomy" sound). FWIW the RFY sounds more refined and I think at full acceleration (up to 8K+ redline) it will sound divine, also because he's got the RFY headers too. Stock NA1 headers are a joke, honestly, they were done that way in order to limit the power to 270hp. Side note: which RFY exhaust is it ? They have a lot of different models.

[@DRBLUESNYC]

100% correct on all counts! Thank YOU for the recommendations. RFY is definitively more refined, and SOS - more raw. We will ask Andy to pitch in his explanation of the version.

[@dadoke76]

The rolling/outside shots are in the pipeline! The RFY exhaust is the GT Exhaust 4 (silent version). I also have the silencers instead of the cats, with the test pipes the sound became too raspy. For me this is the perfect exhaust actually, the sound is always present, but it's not intrusive. I have one drive by clip, enjoy kzbin.info/www/bejne/rIKvipuBqcaLnpI

[@LegendaryGauntlet]

@@dadoke76 I have the same exhaust then :) RFY headers, SARD cats, RTY GT4 silent. Was wondering because it sounded very familiar... BTW i had a full Toda line before, and it had that 2.5K rpm drone :/ But otherwise a very nice sound.

If your "best sounding NSX exhaust" video doesn't include the Taitec GT009, that converts your headers into an equal-length 6-2-1 (high-frequency V12 sound), then you're missing out. See BAUXITER1 old videos for examples with several header combos: kzbin.info/www/bejne/hICtiatmesyLh6M

[@jdmnuggets]

Taitec sounds wild yeah but you're info as far as i know is off. Taitec gt009 is a 2 to 1 single exit cat back exhuast/muffler, not a set of equal length headers. The video you referenced he is running dc headers, which are basically identical to the pride exhuast headers that im running. Most of that insane sound is literally the single exit 2 to 1 muffler by taitec. My understanding is the exhuast note wasn't the goal of that muffler but was a by product of saving weight ( cause race car )going to a single exit.

[@DRBLUESNYC]

That TAITEC does sound great. A more "track" kinda of sound. I also love it, but personally prefer the SOS, deep growl sound that gets aggressive only when pushed. THank YOU for watching and best regards from Dr Blues!

[@egeg-nr4qs]

​@@jdmnuggets GT009 was made to mimic the 6-2-1 header used on the 2009 Super GT NSX race cars (hence the name GT009). I see what you're saying, but it's not really a catback. Especially since it bolts directly to the headers (deletes the cats). It's a tuned equal-length/diameter header extension that converts any existing headers into 6-2-1 (with an almost non-existent muffler). If your existing headers are equal length, it will become a high frequency even-fire screamer.

I am with you! Thanks for watching!
