I've seen people throw db readings around a bit as some sort of descriptor of exhaust volume; I wouldn't put any stock in them. The measurements haven't been done in the same manner from person to person and exhaust to exhaust.

The Amuse is loud, but not 125db loud, unless your ear is in the tip. Realistic peak interior db level is high 80's low 90's, which is still very very loud. The Spoon and J's exhausts are similar.

I agree, it's very very sweet both visually and aurally. I might still spring for one of those if my N-1 makes me nuts in the long run.

The Amuse db's I quoted were a-b'd against a stock system from two different lengths from the tip.

This is why I only mentioned what the Amuse was measured at and no other. Irregardless of how others measure their own systems, if one guy puts sound measuring devices a standard distance from an OEM muffler tip and then does the same for the Amuse system (as was done in this case) I think the effort and the results speak for themselves. The Amuse db'd at 125 and you say it's not really that high because realistic levels inside the car would be more like 80-90db's but an exhaust that, when compared to others, is measurably louder at the tip (irregardless of any particular db level) will accordingly, be louder than those same systems inside the car...it's all relative.

The Amuse is loud, but not 125db loud, unless your ear is in the tip.
Perhaps it would help to describe the Amuse as being 10-15db's louder than a normal aftermarket cat-back for the S2K.

My Tanabe is fairly loud during WOT but nowhere near Amuse-levels. I can't imagine how annoying having something THAT loud would be resonating in and around town, it would almost make the VTEC sound not worth it for the headaches created getting there!

 

Russ,
The only exhaust I've seen quoted at or near 125 db was the Veilside - perhaps you could show me where you got that reading for the Amuse?

In all the reading I've done of people's exhaust measurements, almost never is it mentioned at what distance they were measuring from, under what conditions (driving by, stationary, etc.), and what speed/load/rpm range. All these things have a huge effect on the outcome.

The only two measurements that matter are in-car (stock:79-81 db, Amuse: 81-83 at light throttle, 90-91 at heavy throttle) and at 50 feet. I wasn't over the 92db limit at Laguna Seca, and to my knowledge haven't ever been over 90db at the local autocross. Both venues measure at 50 feet.

My point is that until folks start taking measurements more scientifically, the numbers that have been thrown around to describe exhaust volumes are not valid and should not weigh too heavily in people's decision making process.

Oh, and "irregardless" isn't a word, irrespective of how often it gets used.

Cheers,
--Jason

I got the Spoon N1 racing exhaust and its amazing irritating but also amazing addictive, I can't say if I love it or hate it but in all seriousness I got the spoon exhaust without the silencer, it has a bassy sound to it from 1k-4k and from 5k-9k the sound changes from rumbling bass to a screaming F1-like sound, its hard to explain, when HondaS2K8888 gets the video up of my exhaust you'll see what I mean. If you dont like LOUD then stick to dual. Who needs subs when you got bassy punch like the spoon exhaust

[B]No experience with this yet but, a local shop in town here has one that is supposedly proven to give you some good HP and TQ gains.

 

Hi all,

I have a Spoon N1 exhaust and I like the fact that you can put on the silencers and have a dramatic decrease in the exhaust volume. I usually drive around with the silencers on during the weekdays and I take them off during the weekend cruises.

I noticed a slight change in the driving behaviour of my S2K and the most welcome improvement is that it does not hesitate now during stop and go traffic. The slight change that I noticed is that the throttle response is quicker than when I have the stock exhaust. I don't want to say that I gained some HP on this but it is definitely responds quicker on the midrange rpms.

here is a pic of my Spoon N1:


Later,

 

i have the dual R1 by amuse, i've always been interested in their single r1, but after talk in the forums that it was way too loud for daily driving, no optional silencer, that ear plugs were jokingly recommended for long trips, and further not being able to find a car to hear (i'm still looking for one! jzr?) so i decided to wait for the dual, anyhow, it's full on titanium (piping, canister, tips, resonator, structural pieces), 15lbs, estimated 4 hp gain, as for how loud it is, at idle it's silent, then roars to up vtec and silences out to engine noise above, compared to other exhuasts that i've heard, it's quieter than the hks and tanabe, but deeper and smoother, if not one of the smoothest sounding exhausts period, maybe due to that little tube that sticks out near the cat that i've been told tunes the sound of the exhuast, just like the stock set-up, as for hp claims, i've heard that they were right on with the single r1, so i have no reason to believe that the claims would be false for the dual, haven't dynoed it, but i can chirp second pretty easily even with a hardtop on, something i couldn't do before w/o, as for looks, the tips are really nice, wide, shiney and burnt a purple goldish color, as for the placement of the canisters, they stick horizontally out, i'd probalby prefer it to angle up like the hks, or side ways like the single r1 or tanabe, but at least the canisters remain under the bumper and only the tips protrude, i posted a link early if anyones interested in hearing it.. and comparing it to other systems

 

Thanks jzr!

There are 2 things I would consider when looking at how loud and exhaust is.
1) Am I going to be sent home from my racing weekend for being too loud?
2) Am I going to be able to talk to my date with the top up?

I think the most important db measurement is the db at 50ft in open air (not at 50ft in the dino room). This is what most venues use to measure sound against the limit.

An interior db reading with the top up would also be nice to see.

Saying "loud" or "not so loud" doesn't really mean much - loud is not a measurement - it's an opinion.

I was seeing these posts about 125db and thinking - wow - that's like vintage transam loud. I've heard the amuse - at laguna in fact - and it wasn't that loud. From the hot pit wall I could hear the car approach and pass - and then it would fade away. Loud would be: you can hear the car from the paddock all the way around the track. But then - that would be my opinion...
