I had the HKS Dual Dragger system, and it had a HKS Tag on the Jasma Label so if yours hasnt it may well be the Apexi,

JASMA is the people on Japan who say what the legal noise limit is for a exhaust.

if it meet the JASMA standard its a quiet one.

you want one that fails big time!

Kind of true. JASMA actually stands for (I believe) ... Japanese Aftermarket Sports Muffler Association - their job is to regulate and test aftermarket exhaust systems to make sure they meet certain standards. The only two standards I have seen on systems are...

JASMA SR - Safety Road (or something like that) means its a road-oriented system that is below "acceptable" noise levels.

JASMA RO - Race Only (proper exhausts) class is for out and out Race exhausts, Trust Power EVO 2, HKS Drag systems etc.

Generally speaking non-JASMA exhausts are made by the smaller exhaust makers (Fujitsubo RSR, Kakimoto, Veilside et al) and doesnt mean its loud or quiet, just means its untested

Hope this clears things up.
