the battery shop got PE ECU reader? what if didn't start the car when the O2 sensor removed? remove O2 sensor and connect back without crank start the car?

Can say so. But if u pasang extractor, u need to extend the o2sensor cable. How are u gonna extend it if ur car is still in the exhaust shop?

Hotbits also at top wat.

cannot just simply sambung the wire with cut-and-sambung? or that wire is special wire?

hotbit already branded wor...

sambung straight away at exhaust shop lor... dont the boss not let u diy or ask them diy for u (less than 5 minutes job) mah....

meaning to say go outside install extractor will have this issue

The o2sensor cable can be disconnected from it's socket.. Not sure how much it cost tho, but cable alone no problem la. Just dont farkup the o2sensor can d

how's the sound compared to the stock??
hahaha~~more concern to this since performance and fc is said to improved by other.

i juz reset my ecu
millage / fc has been reset to 0 , i guess this is correct way to reset ecu?
after that i did 1 round testing , the car seems abit jerk

retinted all window of my PE with cap ayam brand with 80% darkness... very regret to done with 80% darkness coz it TOO DARK, cannot see inside the car. in fact 50% will be better choice for me.

If got time can u please record your extractor sound before change bullet or mid box then post here to share. Thanks

due to the degraded of the 1st & 2nd layer of the tinted, the darkness become fair... so i applied 3rd tinted, unfortunately, the 3rd tinted too dark... i should get 50% darkness instead of 80%...

Auto car use swirl bullet better. 
you want to change yours? But need to sacrifice with the sound. Like mine extractor.   

Better acceleration but noisier. Trade off lo.

No, swirl got better acceleration but noisier. What u lose with swirl bullet, u gain with straight.

abang, pick up & acceleration ada lain ka? the straight bullet is quieter, but u lose out a bit in acceleration if compared to swirl. Can brain?

Hotbits is 2.5k to 5k rpm.my one is 5k above

looks like someone aldy get his year end BONUS

Bout RM 20-70 difference per tyre of the same model.

I don't quite get ur question.

With bullet (quality bullet, 5Zigen), it can help muffle the exhaust noise and at the same time provide a little extra backpressure.

Swirling bullet (Wegow), not much sound insulation but provides ample boost in acceleration due to increased exhaust flow velocity.

Without bullet of any form = decreased performance + increased noise, even factory setup comes with a mid-muffler (midbox). If u install the bullet/swirl bullet, u'll be either adding the bullet to the current setup in such a way: 4-2-1 -> (bullet here) -> midbox -> S-flow, or removing the midbox altogether and leaving only bullet in place (usual manual setup).
