sorr not emissions.... seems like its a sound thing

JASMA

Often owners may find 'JASMA' stamped on an aftermarket exhaust that was on their car when they bought it. JASMA is not a exhaust manufacturer, its some sort of organisation that certifies exhausts meet noise standards etc. It stands for Japanese Automobile Sports Muffler Association.

I had Trust MX on my car, and it's quite loud compared to standard exhaust, but I like it after a while. It's pretty quiet when you cruise. The deep bass roar is when you accelerate around 2000rpm, by 2500rpm+ it's quiet again.

Nice.

well, I got a kakimoto cat back, but the muffler was replaced with an american made N1 copy. I got front and dump pipes as well.

Got it tested yesterday for noise and with silencer I'm JUST bordering on legal (90-91db I'm getting, limit is 90).

Without silencer I got 92-93db.

With silencer was @ 3,200RPM

Without was around 3,000RPM
