Depending on the torque band that u prefer, u can mess around a bit with the exhaust setups. Get the swirling bullet with hotbits extractor, u'll never regret it & ur low end torque band changes tremendously.. LCP helps, air filter helps from 3k RPM onwards, or u can go straight for Cold Air Intake. Carbon air intake will help as well, but this requires the dismantling of ur original airbox and replacing it with a open-pod air filter, as well as building a heat shield around it. This works very well to improve low end torque, but high end ur car will suffer kaw kaw..

Once I used the wrong setup (wrong bullets & extractor) on my PE's exhaust system, I went to Duke, press till habis my top speed 160 only. Low end power cannot be felt at all. So it was practically useless, that setup. My car's idling became very bad during cold start due to improper placement of O2sensor, and it scared the shit out of me a couple of time when I step on the accelerator pedal & there's no response. This is because the O2Sensor works with the presence of heat & exhaust gas, and so the exhaust shop fella placed the sensor AFTER the flexipipe (a.K.a nenas), causing the O2sensor to not be able to get any readings during cold start & wet weather because the flexipipe sort of insulated/separated the heat from the extractor & the sensor.

What I did was I revamped the whole exhaust system, chunked away the cap ayam extractor, plonked in a Hotbits' extractor with the O2sensor at the intersection of the 2nd & 3rd pipe, a swirling bullet, and a midbox. Tested the power after that, damn impressed. Then I replaced the original muffler with an aftermarket S-flow, been happy with the power ever since till it's now passed into Zeng's car.

ur setup is for manual wow...Zeng just plug n play can suit his Auto??
btw, ur setup is how much? FC drop or increase after tat?
i heard Zeng car is very silent with this setup. i like silent assassin= +

Nope.. Stock also my top speed 205.. Depends whether ur balls is made of steel, titanium or platinum.. Max I go 215 nia.. With a bit more mods can push it to 230 I'm very sure, but enough la.. Now I'm a sane driver, everyday max speed 110 nia..

Zeng got your monster setup

Yesterday afternoon just back home from KL and i off engine for a while the turn the key to ON i can hear the fluid sucking sound from outside my car, i knew it was the fuel pump cause evey time when we turn the Key ON the sound from behind was the fuel pump ready to pump and feed, but yeaterday the sound i hear was like those sucking fluid sound from empty container but my fuel level are half tank and double confirm my km meter are yet to reach the refuel level. I try few time On and OFF the sound are same. The sound are scary me, but this moning i am not notice this, any one having this sound before. One thig i notice the last 2 tank of petrol my FC improved around 0.5L/km but performance not effected, i am very worried it was the earlier sign of fuel pump GG

U sure it's fluid sucking sound & not ur radiator fan sound? If u drive very fast or accelerate very constantly then ur engine bay will be very hot.. Then ur radiator have to work overtime to cool it down.. But what I can suggest is u can check ur engine radiator water level, and then the reserve tank water level to check that it's adequate..

fan sound and water sound are easy to differentiate and it came from behind not front, One thig i notice the last 2 tank of petrol my FC improved around 0.5L/km but performance not effected, i am very worried it was the earlier sign of fuel pump GG

Hehe.. Sleeper car.. Ppl cucuk me on highway or LDP that time then i unleash the POWAARRRR!!

Hmm..u described the sound as 'sucking water from an empty tank'.. So unless ur tank is empty, it couldn't possibly make that noise. Unless ur pump upside down la.. I will try to look into this then find a tentative answer as to why this happened & the solution to it..

time for u to transplant a manual lah..

But compared to stock,the sound not that much different is it? Any difference when change the muffler in terms of power?

i have try to convinced them the problem..but the mechanic said the new generation of prsona elegance already have the rubber tube hose.. hohohoh..

ok i wil...

I am not sure....i seldom wind down the window, while i turn the key on yesterday afternoon was hot so i wind down the window and heard the sound, maybe you guys help to check the sound out at your PE also.

haha... dun sapu ppl lar...

Got difference.. The note is slightly deeper & bassy..

The muffler affects a lot as it's the last piece in the exhaust system that creates backpressure. Without backpressure our auto PE will have bad top end power..

Slightly bassy sound.. But when moving above 2k rpm it will sound almost exactly like stock..

I think what u heard was some kind of electronic sound whirrrrrr like that right? U can only hear it when u wind down the window or when u preparing to start ur car in a dead night.

haha. serious or not?

Serious bout wat?

Fella with M3 telling u that.. U believe or not??

Aiyo dilemma now.. Dunno where to get engine oil.. Need to go for next service in 100km ady.. Sien..

tesco?
