Don't ask me why but when I got home from work this evening I had a look to see what exhaust I actually have on my zed.

It is a single exit jasma with the code/numbers 051 622.

I did a little search on Google and apparently 051 is the number for hks, but what is the other code/number?

I was under the understanding the jasma code is to do with noise regulations in japan not sure if you can define brand of exhaust from that code mate, someone might know it does look like a hks though.

I know there is sr and ro, which is street regulation and race only.

After searching jasma, Google kindly translated the Japanese jasma page for me which led me to the his info, but still don't know what the second number is.

cant see mine there,Fujitsubo ??

001 on the list I linked to mate

I think I posted the wrong list as I have the list you posted too!

Here's a shitty pic of my (very grubby) exhaust...

Mine says Jasma 001 and then 6 other numbers but I think I just have to note the 001. Fujitsubo.

 

Thanks for list Tomo.

So where wood the no be on the exhaust

If it has a plaque on the back box that says jasma then it should also have a number on the same plaque.
