Just an FYI.....

There is none, and they do not manufacture.

What you see in the store or surplus na may naka lagay na metal tag sa body ng muffler saying JASMA means that it pass the old Japan regulations, its not a brand name!

What is JASMA?

The Japanese Automotive Sports Muffler Association

Basically they certify that mufflers are compliant with the old rules that Japan had, that kept mufflers "Clean"

Kind of tags:







Now that you know, stop asking for JASMA mufflers and be specific if you want HKS, Tanabe.... etc.
