JASMA certified exhausts are those approved street legal in Japan, so the sound should be quite low.

not necessarily low la bro.... i was using a jasma approved 5zigen border and it was friggin loud tongue.gif

Jasma is more like a Sirim for exhausts in Japan....thats it. they kinda make sure it keeps to the noise level (which im guessing they set the bar pretty high laugh.gif ) and also emissions standards. and of course quality control la.

I just asked for the price for removing the cat, and he charges me RM200 including a central bullet for replacing the cat. It is resobably priced? Btw, bro Soulfly did mentioned that adding more than bullet in our exhaust setup is not neccessary. So should i just replacemy cat with a normal exhaust pipe of the same width? unsure.gif

what brand is that bullet eh?i installed a zenden in my car for only RM110 (bullet RM90, installation RM20)..replacing the cat wif a normal pipe of the same diameter resulted in a higher noise for my car...

if you're running carb, changing the air filter will not affect your fuel system.

but does the original proton extractor is quite short and a little bit less in term of its diameter,how come it is equall ? anyway is it true or not...a smooth gas flow in the exhaust system will help a smooth gear change ?

Hi,

Just did the 4-2-1 extractor and midbox in Wei Yip in Cheras.
I leave the piping /muffler later on do.
Why is Wei Yip not good har...wondering..are they cheating?

who had stock kancil 660 here? mind i ask about whether change to whole piping to 1.5" and center bullet + muffle help in performance? i was very wondering cos the car is simple under power a lot and if anything done was not really correct then i will suffer from it =further more......

no matter how u mod it, kancil 660 is really seriously underpowered. it's just a normal commuting car, not worth to mod. better save the money for something else.... think wise.
