Info on JASMA Exhausts

[Eug]

Just wondering if anyone knows anything about Jasma

Exhausts or where I might find some...

Everyone I've asked has no idea, and the websites

are all Japanese (which I'm no good at)

Thanks in advance

btw. the badge number on this particular exhaust is.

JASMA

051

96-000 509

JASMA I believe is just an emissions or quality standard in japan, not an actual brand. Many people get confused on this.

[NA_R33]

From what i have been told Jasma is every Jap exaust, they all come out of the same factory. Although i have also read what Gordon said about it as well so i dont know.

[dAVE]

What predator said... if it doesnt have jasma printed on it then it hasn't passed their testing.

JASMA = Japan Automotive Sports Muffler Association.

It's a standard that; if the muffler is constructed accordingly, they company making the muffler can weld on the JASMA badge. It's all about quality control, JASMA exhausts have to meet a 96db limit, amongst other things.

[BHDave]

I'm with Rezz, the 96db rating will be on a stock car with only the exhaust changed on it though.

Stick on a big turbo with a back cut exhaust turbine and say goodbye to your 96db car.

My Fujitsubo is Jasma rated at being quieter than stock - except between 4000 and 6000 RPM. Just where the EPA test it

The Fujitsubo site has good Jasma info - as well as dB ratings for all products - even sound samples!

hmm... so can anyone help me identify this 'thing'

thnx.

[Bass Junky]

Maybe HKS twin, but I would think they would have a HKS tab on it.

thnx.

Your exhaust is an HKS Dual Dragger... it's a bit of a dated exhaust, I think they stopped production.

are Blitz exhausts Jasma? coz mine is super loud and its just a catback

[Blitz]

I should send you photos of mine Rezz, mines also a dual system like the one above with no visible markings.

[Eug]

Thanks Rezz... do u know whether its any good? or shud i sell it..

what do u suggest?

thnx again!

[Rezz]

Bam: Blitz are JASMA Members... is your car modified much?

Nick: Post away dude

[Rezz]

Thanks Rezz... do u know whether its any good? or shud i sell it..

what do u suggest?

thnx again!

If it was my exhaust, I'd give it a good buffing and get it all shiny, and run it on the car for a while... I can't say that the Dual Dragger are THAT common, so in that case I'd hang on to it, unless of course you don't fancy the dual canisters...

[G0DF4Th3R]

Rezz - nope, like i said its just a catback... however when the silencers in, it sounds like a Camry

[Eug]

JASMA approved exhausts run under 96dB for stocko cars right?

Have u had any or know of any experience with the dual drager?

I cant get any info on it, thus dont know whether or not its worth

it getting it fitted... Dual Canisters are fine, performance wise is more

important imo

[Rezz]

The HKS Dual Dragger came about because of some ground clearance issues with the normal Super Dragger muffler on some cars, also at the time, the dual canisters were the "in" thing... most of the big-name manufacturers had their own "Dual type" mufflers. I wouldn't think performance would be any worse than a usual Super Dragger exhaust system, although it'd be a bit heavier.

If performance is the important thing, the only thing I'd do is sell the Dual Dragger and get a Titanium exhaust (any brand)... the weight saving alone is worth it IMO.

Looks Very nice

[uneekwahn]

Apexi made one called the Dual N1 and Kakimoto also make a dual system.

Bam: Yes, Blitz are JASMA, I have the same exhaust as yours and its got the JASMA badge on it.
