[quote=kazami,May 28 2009, 03:44 PM]yeah.. powerzone extractor is good cause they did R&D and it is not cheap... almost 500 for extractor only.. piping they do have but muffler im not too sure..
for powerzone stuffs... better get from them... they located at glenmarie shah alam...
as for ur air filter, i wouldnt agree about absorb cold air... cause u need heatshields and cold air intake for it to be more effective

not too sure how to explain to u for the mendrel bending... but definitely better and cost abit more...
it is up to u... air filter is much cheaper compare to full set exhaust setup

[/quote]

Beside POWERZONE, what extractor, exhaust piping, muffler and good exhaust mod services shop can you recommence to me?
One importance thing is exhaust system mod is legal in malaysia, right?

wat extractor ar?
maybe u can go ZTH to source for it..
normally exhaust shop can quote u if u want cheaper type...

ZTH is a shops or websites?
I have asked in penang that days, whole exhaust system RM400++.

including: removed catcon, added a bullet (swirl type). also just to note, i followed original piping path.



mine is 4G15 (standard proton lor). it's the fuel injection, the SVDO version
like u said, bad setup will increase FC. i think because if you tuned ur exhaust system for top-end RPM power, you will have weak power at low-mid RPM. and then imagine u drive in city 90% of the time which use only low-mid RPM range, then for sure your FC increase la, coz ur car not using the power u "added" with the new exhaust! or other case is if the exhaust shop not enuf experience, mix the wrong parts (eg straight flow for AT) those kinda things la. i also not expert, but have read horror stories about bad setups. but some car owners also la, dun care FC, dun care pwoer, just want loud exhaust sound. that's why the shops also hantam lor

i think for you, should change extractor next. is your wira using 4-2-1 now or 4-1? I think Wira SE comes with 4-2-1 (as Alvinz mentioned above), but if u are daring, just change to powerzone lor, they might have a better version of the 4-2-1 than stock. Also, change the piping to a larger one too (but not over 1.8" as bro Kazami said, too large for our stock engine)

u also drilled holes in your airbox? or u mean me? i drilled at the square box area only. the part u can remove, right before the filter.
drilled a few holes the size of 10sen each, the wall facing the side mudguard of car (hope can get less hot air ma) and also hidden from JPJ sight

i dunno my top speed now, coz i dont drive very fast on highways (seen too many collateral accidents on highways liao over the years, if expensive imported cars also crush like tin milo in highway, imagine our local cars ) so this part cant comment. anyways, my power starts to feel sluggish upon reaching 5k RPM. the exhaust shop tells me its very likely coz my muffler still using stock. I will change this one as soon as $ permits. gonna get an S-flow 3inch out twin pipe - less noisy, but good airflow for high RPMs. as for which shop, I'm in melaka lei... think tell u also no use

Added on May 28, 2009, 4:24 pmILLEGAL! but from most ppl experience, if you are not very loud, they usually let u pass la, unless that day they purposely find problem with u

Should be same model with mine one, come with 4-1 extractor (SUCK) totally no pick up at all.
I no want big muffler pipe with loud sound. I prefer solid exhaust sound with good pick up and good FC.

All type of 4-2-1 extractor will be same, right? no need much notification on it?
Change air-filter and exhaust system is illegal? I hear that only engine mod is illegal unless get approved from JPJ.

ya, i think then yours same as mine lor.
yup, totally no pickup before i changed. but now, better a bit liao, coz i can drag the RPM higher before pwoer runs out. still... i prefer if the 1st and 2nd gear can have better ratio, coz my 1st gear drag till 3k RPM already losing power 3rd is the best to pull all til 90kph then 4th

also same preference as u. i still remember i step into the exhaust shop, i told the boss that i want quiet exhaust even after mod. that's why he recommend i put a bullet (reduce noise) and also use S-flow (more quiet, but good bass). the muffler.... wait la... soon, SOON!!!
btw, just to share. due to using original muffler, my car not noisy when idle or low-rev. but once the meter reach somewhere near 3k RPM then can hear bass liao. if press till 3.5k and 4k area, very nice sound (proportionate with the torque?), i a bit no discipline, i always tekan till that zone before shifting coz i start to enjoy the sound i think i'm starting to become "ah beng" liao haha die ah

again YES, the mods to exhaust is illegal. actually JPJ hor, any modification also they can create trouble for u de la.
tats y, u modify according to the limit of the JPJ officer in your area la.

cannot ler... cant afford it... no income...

refer here got diy guide... khguan did it before...

http://khguan.fotopic.net/c900753.html

my plug cables vr dirty adi lor... no more red color... become black color adi... hahaha....

proton got speed limiter one meh??...

1. manual or auto, get drop-in air filter is good... at least u wont be suffering at normal low speeds...

2. 4-2-1 is good for low-mid torque... 4-1 is good for mid-high rpm gain... if u accelerate and upshift at 7k rpm all the gears, get 4-1 extractor... if u drive normally and upshift before 3k rpm, get 4-2-1 extractor...

mandrel bent pipings has same diameter throughout the piping length including the bends... this cannot be done with crush bent piping because as the name goes, piping is bent by crushing /forcing the pipe into an angle... end product, u will have a smaller diameter piping at bends... this smaller diameter will create bottleneck effect in ur exhaust gas flow....

mandrel bent machines are huge and blardy expensive... not commonly found in most exhaust shop... if not mistaken, mandrel bend piping involves heating up the piping and bend it slowly...


mandrel bend pipes



crush bend pipes



for ATF, yes if u alwiz drive enthusiastically...
manual gearbox, dun need...

Soli, its rev limiter, not speed limiter
Wonder what was I thinking earlier

As a conclusion, to solve my problem extrator 4-1 must change to 4-2-1.

Actually i decided go for s-flow, since it can perform in low-rev and silence as you has mention. But, one of the mech advice me straight muffler will be more better in pick up and top power. Then, it make me have to reconsider again.

Actually we no need border the brand of the extrator and exhaust piping. right?
How much you did this mod?

Added on May 28, 2009, 7:33 pmthe_catacombs, thanks for your advice.

1. After change to 4-2-1 extractor will decrease the top speed as stock 4-1 extractor?
2. Open port filter will suffering at normal low speed? Drop-in with stock-in piping and box?
3. Can you propose to me whether s-flow or straight muffler and how many inch should i go for it?

wah nicee ... look so easy . but i don have the tools! ...


its just like my condition, after roughly 3k+/- km ... goood good .. anyone here got the tools? ..

btw cata, u know about y the RPM meter will drop to 0? ..
when start engine it will go up like normal, stayed at 700+/- rpm then after awhile it will drop to 0 line ...
when accelerate it will go up woh ....

thanks for ur info & link ...
thanks khguan for the picture guide ..
