JASMA or Japan Auto Sports Muffler Association, is more like our SEMA then Carb...meant more for noise levels than emissions. If you have a header with a Jasma plaque, then it could be GReddy, Mugen, 5zigen, Fujitubo, etc.....either way, it's Legit!

SEMA has absolutely nothing to do with any of this and nor does it make a header "legit". It is Japan's version of our CARB system for exhaust components. It is a company that regulates whether or not a specific product meets the requirements to be allowed for street use.Originally Posted by bigjussin
