m3 bro, here is the place that I install the extractor:
Advance Crew Exhaust House
No.22, Jalan Emas 5/1B, Bandar Sri Damansara, 52200 Selangor Darul Ehsan.
They also sell the extractor too, but compare to zenden one; zenden got very nice out look, but the exhaust position is not match to the original one, to make it more prefect need to do minor modify abit, zenden's extractor need a half meter of pipe to fix it up.
For the Advance Crew Exhaust, I have check it very clear, the extractor for kancil they made, is more light weight then the zenden one, and the exhaust position is prefectly match, but why I'm not buying? b'cause I already buy the zenden one, so later I feel little sad and mad (at least the zenden have a good out look mah ^_^)
