Which JDM exhausts are JASMA certified?

[240fluke]

I have seen that some of the JDM exhausts do come with the JASMA certification stamped on the exhaust.  So which ones are certified?  I believe the JASMA certification is for noise levels in Japan (correct?).  If so, it would be interesting to see which ones are not in that category, but are being sold over here (if any).  Basically I am thinking that this list might help when deciding if an exhaust system for some people will be too loud and be over the 96dB limit of the States.

Also are there any exhaust systems being sold in the states right now that are above the noise limit?  I believe the Trust DD is over the limit and the Apex'i N1 series is right at the limit, what other ones are above the limit?

Interesting thought, however I would not rely on Jasma certs to point you in the right direction. There is no US standard 96db noise limit, it depends on your noise local ordnances. If you want to be on the safe side go with an exhaust that is CARB Legal, those will probably meet California noise standards which tend to be as strict as any.  

If you have questions about specific exhausts you would do well to either call the manufacturer (most JDM companies have us offices or distributors) or post up here and get feed back.

Well to answer your topic question, the only two I know for sure that are JASMA certified are:

HKS Dragger 2

Those are not the only two that are JASMA certified, the majority of JDM exhausts are in fact JASMA certified.

JASMA is like CARB here in the sense that pretty much every manufacturer gets certification for their product; however, CARB has nothing to do with noise pollution and your CARB paperwork outside of California is equally good for writing down girl's numbers and wiping your ass.  A court or cop outside CA could care less.

Bottom line is that whatever your state requires is law.

Most JDM exhausts are certified as uuninja was saying.  I haven't got under my car for awhile but I think my Apex Gt Spec is Jasma certified stamped.

All exhaust systems that are Jasma certified will have the stamp on it and are only sold in Japan.  Many of the exhausts that are for export do not have this certification, even though they are supposedly "JDM" exhausts.  Apex-i for example is supposed to be "JDM", but for our market it is not so because it's more "IDM"-Imported Domestic Market.  As far as differences, I believe it's only the stupid stamp that says Jasma on it, but as far as everything else, it's the same.

I do realize that JASMA certification would do ABSOLUTELY NOTHING for our cars over here. &nbsp;I was just thinking along the lines that if an exhaust did not even meet up to that standard over in Japan, then it definitely would be too loud over here. &nbsp;HOWEVER, I am sure there are exhausts out there that meet those standards and would still fail CA noise pollution laws. &nbsp;I don't know though. &nbsp;I like the reponses to the topic so far, lets see if anyone else has some more opinions on the subject &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/alien.gif" border="0" valign="absmiddle" alt=':alien:'>
