any performance different on the stainless steel and metal piping? for example, stainless steel extractor and metal extractor.

No good meh? pickup faster. Maybe not nice during stop-n-go traffic.

Steel extractor won't rust so quickly, my dear friend. It's galvanized for a reason.

And for chrome extractors, they provide better flow (given that the whole extractor is chromed inside out, not just outside for aesthetic purposes) as chromed surface is smoother than other surfaces (galvanized steel, aluminum, ceramic, etc.).

i might be free.. wanna test ur inspira cvt okay or not?

I haven't checked the insides of these extractor, but I'm pretty sure a real, fully chromed extractor would cost a bomb.
Didn't say galvanized, but I don't know any steel extractor that's not galvanized nowadays.

Mana mau cari? If extractors are made of steel and only steel, not stainless or galvanized, it'll rust within a day or two after installation.

Supply and demand. If there's no demand for it, u think ppl would make those steel extractors?

So that's why ppl don't use steel extractors. Stainless steel extractors are noisier. Galvanized ones are less noisy. Ceramic coated ones reduces heat released into the engine bay by retaining/insulating the heat in the extractor itself only.

no la...
i dun want loud loud geh...
since i have almost all the light mod...filter, SP, LCP
next get a good extractor then tutup my water pipe for modding car.

Good Extractor... then go for FBK lo..... i think RM 390/= siap pasang...

More reason to use Esso.

400 also not expensive , RM 10 /= different...RM 10 now can eat what ? Maybe 1 McD lunch only

I also planning change the extractor. but...no $$$$$, this month Road tax insurance....haiz...........

This month eat roti putih and kari.

Haha... good idea!
Go mamak buy roti kosong, then when the fella give 'darr',
u ask the AhNeNe "Nek, boleh kasi kari ah?',
after the AhNeNe give u kari, u look at the kari it self..."Eh, sorry Nek, i mao kari ikan, ini kari ayam.' but u still put the kari ayam into ur bag. There u got another bag of kari ikan

Bear must eat Kari ikan then only good for your health.
