Haha ok, it's your money after all. But from the dynos that I've seen l don't think it's worth it.

But hey if you squeeze that stone hard enough maybe you'll get a drop of blood.

Yes it does. Sound is determined by the shape of the wave. Loudness is determined by the amplitude of the given wave, which is determined by the amount of airflow in the system. Yes, I've taken engineering classes in college.

If you're going to disregard our input, why ask for it to begin with?

Here's the thing....

I NEVER even stated it could or couldn't handle the flow/amplitude of no-cats. ""a stock muffler handling no cats" was never mentioned nor asked by me! If so, please do quote.

I was PURELY referring to "JRSC with stock exhaust" and NOTHING else!

sw20kosh changed the subject slightly and entangle being "catless + JRSC + stock exhaust" sounding like ass ...NOT ME.

It's common sense it'll sound like ass with zero cats and a stock muffler lol.


Yes.. I know sound is determined by shape, time/speed, frequency (it's actually my second job.. I've been involved in sound engineering and music for 15+ years). Loudness is just another word for amplitude. You'll be surprised how closely related sound, visual and physical matter really is (they all involve wavelengths).

I'm not disregarding your input; I listen to it and take it as very valuable info. But, it sounds like you and some others, disregard mine. I simply corrected you a little in regard to short vs long wavelengths (which maybe a typo on your part); but you can't seem to admit to that.

The stock exhaust, without cats, both rasps AND rattles. The rasp cannot be eliminated; the rattling can.

If deep, bassy exhausts are what you consider a proper exhaust, then you've never ventured into high end exhausts. Deep, baritone exhausts are universally quiet at high flow, high RPM. Think about it.

Huh? I never said I considered bassy exh proper. I actually very much dislike bassy exh. Stop projecting things.

And again, I never asked about stock muffler sound with an uncatted setup (I only mentioned JRSC + stock mufflers (WITH cats) would be an awesome quite setup).

But, thanks for the info about prone rattling with an uncatted setup.

The long wavelengths cause the baffling inside the muffler to vibrate... which is what causes the nasty rattling. It's a result of the muffler design, which was designed such to work in conjunction with existing cats on the stock car, to be as cost-effective as possible from the factory.

Now, lets take another example. I have no cats on my S2000. Zero rattling, only a mild rasp at WOT.

I think you're talking about header gains in an NA setup. Then yes, that would be like trying to squeeze the last drop perhaps.

I was talking about header gains after a JRSC kit though. Wouldn't that have much better gains vs NA?

Thanks for the info.

Yes, I do notice many stock exhausts "rattle" ..especially with age/wear. Cheap build quality makes perfect sense. It ain't even insulated after all.

I always plan to have at least 1 cat anyways (I dislike hanging out in public smelling like petrol).

Can't wait to see future vids of this.

Also can't wait to hear 3rd party reviews of JRSC owners using DT's Flash&Go and/or FlexFuel Kit/Tune.


Anyone here running JRSC + DT Flash&Go or FlexFuel?

Idk how this got blown out of proportion regarding sound/rasp/rattle...but here was my original reply/comment regarding the JRSC and stock exh. I was merely being enthusiastic about it.

Yes, I've asked several questions in this thread; but, only in regards to power, tunes, e85, upgrades, parts, headers, etc.

I did not once ask a single question regarding sound. I think that's sw20kosh's problem

No offense but can you ask your questions via pm's to the appropriate people/vendors or just call CSG/Jackson Racing? You are adding senseless clutter to a 5 star thread.

I read your posts and it makes me want to shoot myself in the face because all your questions and comments help no one, including apparently, yourself.

And since you will no doubt get all defensive and claim your posts will help out people who view this thread in the future for info....

No, it won't because people will either waste time like I did actually reading them or they will just skip over them entirely, like I should have done.

Damn, so salty.

Lets get back on topic please

[Churg]

So, if my car is already extremely loud, a supercharged setup like the JRSC would make things louder?

I'm definitely in need of more power, but probably won't upgrade to something like this for another year or so.

Only at WOT. For normal cruising volume is essentially unaffected.

Like I mentioned, only when I downshift do things get crazy.
