You apparently understand the meaning of elucidate, but do not wish to do so.

I was merely asking to what "the quiet one" referred.
Are you asking about an aftermarket exhaust that is quieter than stock? To my knowledge all the aftermarket exhausts available for the RX-8 (other than something custom made to be extremely quiet) are louder than stock. Mine is probably the quietest of the bunch.

Thanks Bob,
That is what I was looking for......the quietest of the bunch.
You did do a nice job.

Kind regards,

I have a custom system made by Spintech in Riverside, Calif.
They will be making it as a regular production model.
I think it is quieter than the other aftermarket systems, but a little louder than stock with a different tone.
I am awaiting a call from Spintech to do some dyno tests.

I just wanted to post a couple of video clips that I took of my 8 getting some dyno time after the installation of my RX8Store Exhaust. They were originally digital video that I transferred into an mpeg, so the video quality isn't the greatest but you'll enjoy the sounds I'm sure.

Jason & Xavier from the RX8Store as well as Sea Ray (all the way from Kentucky) were there for the fun. Special thanks to RX-8Freehk who put these into a format that the forum would take. There is one more video that is still trying to make it's way back from Germany where Freehk is at but enjoy these for now.

That exhaust sounds nice. Not too loud.

Did they do a before dyno and if so, what kindof hp gains did it make?

Here is the third and final dyno run video for the RX8Store Exhaust. I love this view! :D

Here are some MP3's I recorded of the Hymee Catback.

Start and Idle with a small throttle blip (521KB)

Short drive with windows down (738KB)

Start, bigger throttle blips, 1st gear drive by (917KB)

Best to "Save As..." them to your hard drive.

And there is before and after dyno tests on this thread:

Hey guys< I am about to order the Borla system. It appears to me for cost $600 roughly and performance which is a supposed 12hp gain I read in another post it make sense. The fact that borla exhaust sounds deep and throaty I love the idea. Please can anyon etell me otherwise? Chime in please!

I would be very dubious of any catback system that claims 12HP! There is honestly not that much there to be gained.

BTW - Here is a pic of the recent Rotary Engine Track Day:



There are 7 RX-8's in the photo, and 4 of them have the my Hymee Enhanced "Cat Back".

We measured one of these at an honest 2kW which is about 3HP. That is in-line with what Racing Beat claim for theirs.

Cheers,
Hymee.

What about Mazdaspeed's exhaust? What are the specs on that? Which is exhaust sounds good and loud when you step on it but isn't always overbearingm someone mentioned to me HKS ?

Any information on the weight of all the currently available aftermarket exhaust system. Thanks

Hymee

iTrader: (1)

The shipped weight of the Hymee system is 17kg. So take off a few kilograms for the big carton and all the bubble wrap.

Cheers,
Hymee.

why cant i see all of the rx8store exhausts? i ordered that exhaust yestrday and havent heard a clip yet. does anyone know why i cant see them?

bobclevenger

On the first page of this thread there is a summary.
On it there is an entry for the RX8store exhaust.
Click on "more info" to see it.
If you want to HEAR it, I have bad news.
Unfortunately the link to the sound file does not work any more. I assume that RX8store has removed it from their server, but I don't know.

Any info on the Tanabe?

bobclevenger

I have none.
