Japanese Automobile Sport Muffler Association. They're an organisation in Japan who assess car exhaust system noise level.
To have an exhaust endorsed by JASMA, normally means that exhaust is reasonably quiet ! ;-)
thanks youngsyp for answering my question about the jasma tag,it seems to me that a few people on here like to think their clued up not mentioning no names,i did read up that it was to do with the exhaust volume/tone etc, after i was told it wasnt a make of exhaust but the person that told me that never left a reply after i asked them what it meant.
