dear all,

the purpose i create this topic is to let everyone be alert and aware when you want to do your exhaust at any wai heng outlet,today i drive one of my parents car to wai heng at kota damansara to change the manifold only to 4-1 type,is a proton saga fl,new car just on the road about 1 month + only.so when i drive in,this guy fix it for me,at first when he was unscrewing the manifold nut,he accidentally drop 1 nut at the engine,i'm not sure if he picked it up or not,anyway i didnt bother much also,then he proceed to fix the manifold,i was there all the time,the car also did not move at all,then when everything is done,i paid and start my car,it was raining outside also at that time also.Then when i start the car,i heard some sound like a nut drop down,then i didnt bother,when i on the aircond,i heard a sound like a bullet shooting,then the guy at the workshop told me to stop the car,i got down,my radiator pecah already,water was leaking fast down at the floor,upon checking,we found the cause of the problem,there was a hole behind the radiator,and so that's the time when i start to ask him,so how?u have to pay me a new radiator because my car is new and impossible is my own fault,when i drive the car all the way i on my aircond also no problem,reach your workshop also no leaking,after u do the manifold then this problem got already.

the way they handle problem really not professional at all,guess what he tell me?he says maybe is the stone kena the radiator?i was like,wtf,bro come on,if stone kena it should be in front,not from behind rite?i keep telling him is the nut cucuk until the radiator got 1 lubang already,he insist is not his fault and said if u can find the nut or any scratches at the fan or have mark then i will pay,he act like a gangster towards me also,so he tell me he cannot pay for a new one because he not puas hati to pay,not his fault,he say either he ask his foreman to seal it back or he get me a 2nd hand radiator.If any of you is on my shoe,what do you think?will u accept this offer?i mean your car is only 1 month old,not even your fault,is his fault and u have to bear with it?after a while i call 1 of my friend come,he is a foreman too and upon checking by ourselves,we find out that there were actually scratches mark on the fan at the side,confirm is something hit the fan then hit the radiator,just we still couldnt find the nut,the guy tell me to leave my car there then 2moro they sent someone to fix it,but i did not want to,why?because if i leave my car there,the next day when he and his foreman check and found the nut cucuk at the radiator or drop somewhere at the engine bay,they will hide it and pretend nothing ever happen and just replace me with a old radiator.

So never ever send your car to all this wai heng shop,they really not professional at all and because they do wrong,they have to pay with own wallet they will twist and turn until no need to pay so much,if i know such thing will happen today,i rather go and do at other shop more professional and pay more a bit.He can someone say i frame him say is his fault,say the nut,even u yourself also not sure whether is the nut or not,he said,i was like the hole at the radiator is same like a size of a nut,because the new radiator will cost him few hundred,whereas seal back cost rm 100 + or 2nd hand also still cheaper so sure he will keep twisting it,really unlucky today.

What are you talking about?

he might becomes a " water fish "

not water fish lor,is his fault,he have to pay for it no matter how,2moro me and my father is going to the workshop and follow them when the tow the car to the foreman workshop,no matter how we are going to quarell with him until he pay for it.if u are on my shoe,u will not say this word he is waterfish liao,am i rite?i bet u will screw him and taruk him until maybe fight,why?simply because he cause you have no car to drive for half a day 2moro and make u have to take 1 day leave.

Update what happen again tomorrow ok?

sure,i will,i here just to warn and let u all know abt what happen so that others will be careful when selecting workshop to install anything,for your info the other 2 malay guy was also there,quite fren with him,they drove a myvi there,when they saw what happened,they totally silent and dunno what else to say but maybe perhaps quite worried with their car too cost was handled by them,if u say this is nasib,my luck no good,okay,i admit,but this 1 is 101 % confirm is when he open the nut,he dropped it somewhere,this is human mistake and not professional way of doing things,then some more talk like a gangster back,is this the way to do business?screw them man,no next time for me anymore for this bah lia workshop.

Erm..maybe tomorrow i'll come down and ask him. I always go to this shop, no issue at all. change my muffler few times.
Last time got issue with a stupid red EG. Now u pulak

bro,i am also his customer b4 lar,one of my fren introduce him to me 1,my proton persona also 1st time go to his shop do,no problem,i am not saying he is not nice,he's nice,i'm ok with it,barang murah,takpe,i faham,u pay this much,u get this much,but dun tell me i pay this much,to the extend until radiator pecah?when problem arise,huh,this is the time when the pistol point at each other,u say me i say u,no point,rite?the way he handle things,not pro at all,he just cincai hope can settle so that he no need pay new 1,just because he worry for his wallet,u get it?anyone also sure piss off what,new car like this happen,2moro i am going there to the workshop,after they dismantle the radiator,and if can find the nut cucuk very deep inside the radiator,i make sure he eat the whole nut,coz he was saying so big ma,impossible is the nut,not the nut 1,like trying to push the problem back to me,is this the way bro?u fikirlar sendiri.

actually already heard a few bad comment of the above shop from forum...no matter how, workmanship is important..

same goes to brothers 1,this kedai all cannot go 1 lar,do things separuh air only,when problem come out,want to speak to the manager or boss becar also tak ada,so buy or purchase at your own risk bros.

i feel sorry for you TS..

btw, changing to aftermarket extractor will void the warranty of your car rite?

Erm in fact I took my friends' Swift to Sunway branch to fix exhaust tip. I took a pic of them lifting up the car just for the sake of it. When done, I noticed a scratch on the back bumper (very obvious cos it's a white car). Initially I thought couldn't be they scratch it cos common sense they didn't touch the bumper when fix exhaust. When I look back at the pic I took earlier, found out totally no scratch at all. A bit pissed but they can't do anything so the scratch is there. Sigh..

wai heng sucks la.. try everco sunway, more expensive but problem free..easy..

I also kena last month... Next time i will warn them if they place any nut in the engine compartment... $%^&* Sealed back and service the radiator cost me RM120 afterwards.

Happened in a accessories shop. And yeah, i was like you noticed they dropped a nut/screw when disassembling my headlamp..

I didn't notice my radiator until there's a loud knock from the engine compartment and the radiator coolant smell starting to leak... there goes my radiator $%^&*(^&*(

I'm not trying to defame anything or anyone. The thing is, I wouldn't want to part with my hard-earned money with a trip down to Wai Heng. No way.
I'd rather go to Drex

Drex not doing the welding job. Hope u know that.

Added on April 10, 2011, 7:31 pmIf u're saying that his fren doing a nice job, i'll say it is not.
My rear skirt burnt coz he pull my piping and the muffler touch the skirt. But no complain. No big deal.
But still, TS case is a big issue

This post has been edited by Azuma-kun: Apr 10 2011, 07:31 PM

Imo, its happen due to the mechanic/foremen bad habit of placing the nuts on any flat surface of the engine and when the lift the car up, these nuts can move/drop.

Well to be fair, I didn't read TS' statement and I didn't know that he went there for welding job.
I was more like telling TS my position that I am not going to Wai Heng for anything, be it exhaust or welding.
Some for those Wai Yip. Of course I was under the impression that TS went there to do some exhaust-related stuff, so I'm saying that if I were to do my exhaust, I'd rather go Drex's or maybe Speedworks
Sorry yeah

That aside, I don't have confidence with those chinese ah bengs (the one I saw near my place) to do anything

We just wait for the tomorrow to see what the result.

I still think jaafar is the best in terms of workmanship n welding......they take their time but they do it right.....just my POV feel free to disagree

at Jaafar, u get what u paid la..

Been to Wei Yip Cheras main branch, no problem with their workmanship, in fact I'm quite satisfied, just that the products there are all replica/cheapo items la...

ur saga fl 1 month only.. why drive to outside fix exhaust liao ? should drive back to proton service center right ?

+1..

automatically the warranty is void now..so rugi meh

I think only the parts that have been changed is voided of warrantee? Enlighten me. But then the radiator is caused by carelessness of the exhaust guys, just get over with this and get yourself a new replacement radiator. Try to ask the exhaust guys to pay half of it at least.

i also got bad experience with wai heng.. its actually someone in garage sale who bought me there.. he is quite famous for doing replica exhaust though lol..
last time change my wira exhaust system and somehow they burned the o2 sensor.. when i drive came out black smoke they said is normal then i ok lor.. few days passed, car no power, fuel consumption crazy and damn smelly exhaust.. i find maddriver and he diagnosed is the o2 sensor fault

The main issue is not the car warranty period. But workmanship. It is true that the damage is done by the shop and they should pay for it. TS should take picture of the damage. Ask them to raise car again, take more picture. Got consumer tribunal remember? Can take to task.

http://ttpm.kpdnkk.gov.my/portal/index.php...id=50&Itemid=36

And if i want to be sarcastic, i would say...

"Why the hell did u change the manifold when u should only change the muffler to change the sound?" What kind of power increase u think u going to get? And on a car only a month old??

But i already passed this phase. I'm a guy who have spend RM750 on Wai Heng before. Got problems here and there. Last spend additional RM300 and problems fixed. U gotta learn that with Wai Heng, Wei Yip and such, they all sell "under packed" exhaust mufflers. And also incorrectly matched pipe diameter with steel wall thickness. This 2 enough to know any system they make will fail in many ways.

actually my dad complaint the car no power,fc very high and u know....proton ma,i already told him from day 1,if u plan to buy this car,be prepared to mod it,coz no power and high fc + many problems 1.Then after they get the car,they complaint this and that lor,then my dad say screw the waranty lar,just mod it,then now the car only changed the manifold and add 1 voltage stabilizer.some more actually before i come i gave a call,i asked 4-2-1 how much?he said rm 150,then when i reach there,he giveme a 4-1,and tell me 4-2-1 more expensive,i was like,a bit pissed,but then,still can use also and can feel the power so i didnt bother much.

i purposely took emergency leave 2moro to settle this prob coz my dad have been screwing me up,coz is a new car and this ppl do wrong still dun admit,serious,if i find the nut stuck at the radiator 2moro i sure ask him to eat it then no need talk so much,just pay for a new radiator.if anyone of you plan to go there,pls think properly,is it worth it?when problem arise,they might not want to pay and push back the prob to u,luckily my radiator pecah right inside his shop,imagine i reverse and drive less than 500m pecah dy sure he say not his fault,u drive drive the batu hit from inside?so stupid answer he give me,tell me the stone hit from behind the radiator,if he is pro enough,sure he knows normally those car outside the bumper there the radiator got lubang coz kena stone and etc,but inside layer all very nice 1,no sense at all.

Annnndddddd.... ur solution to mod rest in the hands of an exhaust shop..... ARE U INSANE OR WHAT? When i did mine my car was 30 years old. No risk. 1.3L car what do u expect? My god people nowdays......

Any photos on the leak radiator?

no pickup, why you put 4-1. Worsen the situation. If i were you, i'd go wor hotbitz 4-2-1. At least its proven horsepower gain from those cap ayam extractor.

+1

Well said.

Rather go for Hotbitz or Powerzone or the R3 also better than those cap ayam...

bro,if everyone got $$$ to pay for rm 400 + manifold then nvm,the prob is my dad just wanted some pick up and better driving,so i thought just a cap ayam exhaust is ok,i already said,is okay if the barang is cheap,i dont mind,but the workmanship really tak boleh,somemore last time when i mod my persona i can still go back and claim at proton,no issue at all,just talk nicely to the sc only can settle already.If i want to claim this radiator frm proton,i think maybe can,i can just ask them to install back the original manifold and try to claim back proton,but alot of work lor.

imagine just because of the warranty then u dun mod anything,have to bear with the car no power,no pick up,makan minyak for few years?at least i think after changing manifold / air filter + throttle sensitive adjustment the car is much better than stock now.i know sure alot of u saying,why buy this car at the 1st place?reason is because is cheap,cheaper than other car,is a bargain,my dad bought it a baseline auto for my sis to drive.anyway 2moro 9.30 am have to be there,drive the car to the workshop then c what's the situation,open the radiator,check then confirm dy will taruk him kau kau,i'll try to take a pic 2moro for you guys to see k.

No offense but for RM400 budget changing to lightened crank pulley will help more for pickup...

Good luck on your claim, previously also had some bad experience with Wai Heng, bad welding job, exhaust leaking after a month. The car also became noisy and no power after changing exhaust at Wai Heng. Beware that they will put your cataylst converter away, and hope you forget to claim it back. These 2nd hand catalyst converter can sell for RM80+.

You or your sister who drive the car?

not to say warranty or what la. Sometimes mod car also have to be smart la, I also use alot type of extractor before. I waste almost 1k on extractor setup then went to powerzone. for tuned extractor.

What i am saying is that, why you put 4-1 extractor if your problem is pickup and fc? 4-1 is for high revving, while 4-2-1 is for street setting where torque is gain. Anyways. I also have alot of bad experience with waiheng/weiyip/chinaman exhaust shop. Thats why i never touch my exhaust anymore. Sick of it ad. Good luck on your claim and future modding.

Must teach this kind shop who cheap people money, why not you go complain and take him to tribunal court

400 for a crank pulley worth it ???
400 ???

ur solution to bad fc, bad power etc is by changing exhaust.. very the pandai

Improve the fc by changing the way you drive. FOC

if changing manifold can save fc i think proton ppl should have deployed this method long time ago, unless u are probably smarter than those proton dudes.

smart guys really get it.

u dun do anything,the car also makan minyak,at least u mod the car,change the exhaust,the car feel powerful therefor u dun have to tekan so much and in the end might save petrol.even my own persona i mod the full exhaust now my car have power and more save petrol than b4,totally more smooth and not like dun want to go when tekan.

by the way this car is for my sis,so just a light mod will do.yesterday when i drove the car to park somewhere else i already can feel the power is more smooth and easy to rev.later a while more i am going there to settle this shitz...

---

Added on April 11, 2011, 8:00 ambro,for your info proton normal cars didnt change any manifold,but their r3 model did,that is why the model from r3 cars all have their exhaust changed.Also for your info if u mod the manifold,you will be also throwing the catalyst converter,which is restricting the gasses from going out fast,in term will lead u to better performance,just like a water pipe,u open,then the water flow,if u put a filter or something to block at the middle,the water will flow out quite slow,not fast enough,like is clogged.also bro,if proton can change the manifold for all their standard cars then R3 can closed down dy,same goes to other exhaust shop out there,rite?anyway i always also never think that the proton dude is smart,they are so dumb,if they are smart their cars wouldnt have so much problem and complaint.

Warranty only void for the extractor lah.. Dont say u change extractor they go void the whole car warranty.


Btw for TS, some advise for u as we Personarians have been experiencing with so far (same case for saga FL cos the engine are technically the same)

1) modding the extractor ONLY voids the extractor part. Wont void the whole engine.
2) If want to claim warranty go to COSE. Damn easy to claim even if u mod ur car.. Install 17" rims also can claim for replacement discbrakes. XD
3) U want more low end torque go for Hotbits. U want high end power go for Powerzone. Hotbits the pipe diameter are smaller => faster gas flow => better low end torque. But top end power will be somewhat restricted compared to Powerzone. Powerzone extractor does not improve pick up much. Marginal increase, but top speed increases alot.. We are talking of reaching 220kmh here in Persona 1.6 IAFM with light mods.
4) IF and ONLY IF u have 4k lah.. Mb ur budget lesser, I can list the stuffs to upgrade in the following order.
1) Denso 0.4mm Spark plug
2) Works Engineering Drop-in Air filter
3) Grounding cable (VS barely gives u much improvements except smoother shifts at high speed)
4) Full exhaust set up. Extractor first if u dont have the budget. Then 2 swirl bullet or 1 swirl + 1 mid box followed by S-flow.
5) lightened crank pulley
6) lightened cam pulley

For engine maintenance
1) Caltex Havoline / Castrol Edge / Castrol Magnatec. Please dont use Shell Helix Ultra/HX7 .
2) AMSoil ATF
3) The correct brand of petrol. For best power Caltex > Esso > BHP > Petronas(this was tested with old Primax, the new Xtra fuel has not been tested yet). Shell cannot pakai at all. For best FC Petronas Xtra > Caltex > Esso > BHP.

These are all tried and tested by LYNPPC members as we all become white mouse and test different setup for best FC and performance. XD
LYNPPC - We kinda spam quite a lot there.

You should have kept the car stock standard and drive around for few months before modding. As car still new, engine still tight and FC will be higher. FC will be better after 10000km and 2 service.

ori exhaust is restricted that y better save fuel.

if u mean better power then why r3 exhaust built

sorry..i'm not really sure about Proton SC procedure

hope Wai Heng will admit their mistake..

better call up the person who always promoting Wai Heng in Lyn la..

bro Kweng84..maybe he got solution for TS as his name is also at stake

Ori exhaust are restricted to comply with emission standards imposed. Restriction do reduce power, but with lesser power, higher acceleration is needed to speed up and higher amount of throttle opening is required to reach the speed intended. With better flowing exhaust, more power is produced at the same speed, so lesser acceleration is needed to maintain speed while cruising. Just my 1ringgit 90cents of opinion.

Nvm.. Knowledge is power, just sharing what i learnt here..

Btw one of our forumer went to Kweng's shop in Wangsa Maju, VERY bad experience. It shows that the shop knows nothing about the basic principles of exhaust. He went to change extractor due to raving reviews and the reputation of Kweng, on the extractor the o2 sensor is located AFTER the nanas, and the nanas is triple insulated. Since persona o2 sensor is not the preheated type, the car was terrible and acceleration was literally zero. U could floor the gas pedal and the car would just continue at its own pace without and acceleration..

exactly same case with my wira.. never trust those ah beng shop! go to reputable one!
penny wise pound foolish

These know nothing ah beng are every where not only car workshop. It happen to home lighting wiring, toilet piping n leaking as well. Langsung no basic common sense knowledge n just talk c0ck giving nonsense craps. everytime I see these ah beng, sure i ask a lot question to them before deciding to change/repair anything. I don't mind paying but must solve the issue. I am not paying for getting problems.
Sorry if I comment out of topic.
Anyway, hope TS will claim back his radiator.

or maybe TS could source out for used radiator...

you pay peanuts..you get monkey..but what did you expect man..you really do get what you pay for.

saga 1.3 is cheap, no power..bad fc...expected lah..
go wai heng is cheap, rubbish workmanship..expected lah..

haiz dont lah so butthurt.. Pay cheap things for low prices doesnt means that they can simply do shoddy work on ur car right?
I pay RM280 for steel exhaust doesnt means they can drop a nut in ur engine mah.. I wont expect the exhaust to be worth RM280 or more. But at least i expect a decent service where they installed it and give it back in usable condition.
Is it that if u pay RM500 for extractor then only the mechanic must hold the nuts somewhere safe and dont simply put in meh? Sarcastic hypokrit..

I'm not sure whether to reply in harsh manner or sarcastic manner. But the truth is:

You shouldn't modify anything related to the engine for a merely 1month old Proton Saga FL. If you buy a Proton you should be more aware about the warranty. What happens if your car breakdown when your warranty is already void? 3 years warranty went down the drain already.

Lack of power? No pickup? Perhaps you expected too much from a 1.3L sedan.

R3 redesigned the exhaust to let the engine make more power. They have never mentioned any fuel savings. Don't be smart. Any Ah Beng shop cannot make exhaust system that can "guarantee" fuel savings. If there is, their advertisment would be "Tarak tipu, kereta laju, minyak pun setuju" U get what i mean? And which exhaust company claims fuel savings from an exhaust change? What these guys do is copy other brands products and mass manufacture it with lower grade steel.

Original exhaust is the best. And do not need to teach anyone about engine pulse and cycle per combustion ok? The blardy book is so damn thick, exhaust making is a course by itself.

good one zeng... thumbs up ehehhe

Correct me if I am wrong here. For the bolded phrase, I thought is the other way round? Hotbits - increase top speed while Powerzone - increase torque hence increase pick up?

Do enlighten me. Thanks otai-otai.

although hotbits and powerzone are the more famous brand among car enthusiast what about a cheaper brand like wegow? does that consider as cap ayam anyway? I find that their stuff are well pack, mandrel bend and looks extremely fine.

i'm user of powerzone extractor..my fren was using hotbits extractor..i can sure is powerzone is for high end after tested..

THanks.. Im sure both of u are enjoying the plugs and filter..

for apple to apple comparison.. Hotbits extractor only vs Powerzone, Hotbits primary pipe has a smaller diameter to increase exhaust velocity producing the vacuum and scavenging effect on the intake valve, therefore drawing more fresh air and fuel into the combustion chamber to produce more power. However when u reach high rpm the air velocity out of the exhaust valve is high and the smaller diameter hotbits primary becomes a restriction to maintain gas flow.. However powerzone primary tube are bigger in diameter.. In effect low end torque isnt really much improve due to the primary pipe not playing a major role in scavenging, and it solely relies on the secondary tube to create the drawing effect.

As what samwongjyhhorng has mentioned. We LYNPPC did a TT session racing up genting and back down to kl last saturday. It has been proven that hotbits did have a restrictive effect on top speed but providing much better acceleration instead.

Sorry bro...have not heard bout this brand... May b others have.

Added on April 11, 2011, 9:46 pmThanks for the information. Will put Powerzone 4-2-1 extractor in my consideration list when I am ready to upgrade aftermarket extractor.

This post has been edited by jason4883: Apr 11 2011, 09:46 PM

hehe..high rpm(from 140-180) powerzone very shiok..low rpm(0-100) then is hotbits more syiok

---

Added on April 11, 2011, 10:04 pmbut i make clear 1st at here..powerzone extractor finishing not nicer than hotbits..i means u can c d welding point from outside,but hotbits one u cant c it bcoz is weld from inside..according powerzone people told me,weld from inside will a bit affect the air flow,but no sure whether is true or not..due to tis point,many of persona club member decide to change hotbits ady..for me is ok since the powerzone people has told me tis b4 i bought it..and is under the hood,so i dun mind it lo

This post has been edited by samwongjyhhorng: Apr 11 2011, 10:04 PM

Wegow is cap malaysia one.. But the quality seems good.. Too bad its not available easily.

LOL.. U want top end power?

---

Added on April 11, 2011, 10:09 pmNo lah.. we didnt change to hotbits cos it looks better lah.. We are trying to compensate more for the Campro's poor low end torque.. At high end there we got enough power to tapau the Myvi's and vios'es on the road..

This post has been edited by ZenGTMM: Apr 11 2011, 10:09 PM

oic..sori tat i misunderstanding so i need to try whether can tapau new city or forte at 140kmh above..hehe

I believe my pick up is fast enough, with my current setup. Now looking to improve my top end power.

okay guys,sorry for my late reply,so this is the scenario,today early morning me,my dad and my mum together we bring the car back to his workshop.Then my dad was also quite steady today morning,his tone was higher and temper was more hot yesterday,he didnt taruk him this morning except for my mum which gave him a few words -->my nasib malang lor,what to do,purposely let him hear 1,then my dad told him,okay lar,now argue what also no use,u promise me u seal it back,no problem.Please do it nicely,i dun want any problem ok,he said to my dad he warranty it,if any prob then he sure jia lat 1,we sure find him.

so the car is fixed,he's also lucky coz my dad is steady and no point also if quarell,coz he wouldnt want to pay,just talk cock like aunty uncle ah,if i change a new 1 hor,my foreman say wouldnt be better than now 1,i was like,of course lar coz u not changing the original denso for me.i told him got mark and scratches at the fan there,he keep asking where where?i tried to search but couldnt find,if take the radiator out i believe sure can find the mark and nut stuck at the radiator 1,then at about 1-2pm,my dad collected the car,so far no problem,then i called him,so how?what is the problem?i think he dare not say also,he just tell me dunno wor,my foreman couldnt find the prob also,i think he knows the truth dy,he's just hiding it from me coz what i say was right.

okay,so the part with the radiator is solved at the moment i think,actually i wanted to fight with him,no matter how also fight back the new radiator,but then,my dad have this thought also,if keep on quarelling,he dun admit then will keep wasting time,in the end we suffer coz no car use.He didnt even say sorry for your info and i think he dun have the $$$ to pay lor for the new radiator,my dad was steady anyway,my mum was kindda piss off,like want to chop him into few pieces coz is a new car.okay,then my dad tested the car,currently the car only have volt stabilizer and i did ask my fren to help me adjust the throttle sensitive through the pedal there b4,air filter still standard.He told me,not much diff,maybe a bit better only,so when i came back from work today,i tested,so so only the power.

---

Added on April 12, 2011, 1:01 amafter that i took the works engineering drop in air filter from my persona and place it in the saga fl to test it,me and my dad got a suprise,the car performs very good,got v-tec sound some more,no joke,we test and test,can tarik the rpm until 6.5,pick up was very good,tested with a wira modified exhaust also near my house,can manage to potong him,i tested it with my fren standard proton persona also,guess what?my fren lost to my saga fl in term of pick up till mid.is a 4-1 manifold,i want to ask,4-1 as far as i know is for top speed or drag,but this 4-1 if add drop in air filter totally perform like a diff car,why huh?pick up damn good,no joke.

my dad says this car now can save petrol 1,coz less power,u tekan more minyak,car got power,got pick up already,feels light at pedal,no need tekan so much so sure will save petrol 1.when the car reach 3.5k rpm then like got v-tec come out dy,hehe...just tarik till almost redline all the way,i think very fast already sampai 120-130km.overall he says he is satisfied with the performance,the barang is okay,but they really not pro in handling prob only.next time no more business for wai heng liao,i will go other place and do,also i will make sure the shop trustable 1,no more tepi jalan bah lia exhaust shop.

---

Added on April 12, 2011, 1:09 ambro,trust me,no matter how long you service,the car still will be the same,not much diff 1,already alot of ppl complaining proton cars very high fc,some ppl after mod get better fc?believe it or not?i got a malay fren,drive satria neo auto,no cps no nothing,normal campro,his mod is 4-2-1 exhaust,piping 2 inch,no muffler some more,middle i dunno lar,maybe 2 bullet,then use open port air filter,cam pulley,crank pully,ems 1 pro neo from works,his car can get near to 500km for full tank,that also he got tekan sometimes like racing mode,how to explain that?

bro,no offence k,i am ok with the ori exhaust,but what i am seeking here is a more smooth drive in the city especially with jam and etc.okay now we make a example,car 1,standard,car 2 mod air filter and manifold,if this 2 cars climb genting hill together,u think which car more power?more save petrol?letme tell u,i have experience it b4 myself,if u drive a standard car,sure no power,especially with the campro lagging at low end,even with iafm is crap,trust me,in the end,u keep tekan minyak,drop gear to 3,or maybe gear 2 ( this is for automatic k,both car 1 and 2 ) when u reach the last few corners.Whereas for car 2,u will feel the improvement,easy to climb hill,using d,all the way up,only until u reach more than halfway u might need to drop to gear 3,depends ok but still u only tekan a bit minyak the car u feel can climb,not like car 1,have to tekan and tekan also no go 1,jia lat lor like that,the minyak all wasted coz u keep tekan and tekan ma,no power,i've tried it,the after and b4 mod feel up to genting and the fc also,that was with my persona,with 4 ppl in it.

I like your question.

[quote=ZenGTMM,Apr 11 2011, 11:35 AM]
Ori exhaust are restricted to comply with emission standards imposed. Restriction do reduce power, but with lesser power, higher acceleration is needed to speed up and higher amount of throttle opening is required to reach the speed intended. With better flowing exhaust, more power is produced at the same speed, so lesser acceleration is needed to maintain speed while cruising. Just my 1ringgit 90cents of opinion.
Nvm.. Knowledge is power, just sharing what i learnt here..

bro i agree with u,coz the ori exhaust is restricted,that's why boh power,not smooth enough.my own proton persona also with 4-2-1,piping 2 inch and 2 bullet + s-flow muffler,much better than b4,no regret,really.Just this time so unlucky with the saga fl

+1+1

I would said exhaust setup will be the last modification and depends on your driving style. I wish i can get some branded exhaust like Tanabe, HKS which calculation by professional but unfortunately its impossible.

The diameter of exhaust pipe, angle, distance, sensor locating, resonator & etc will cause different result. But this is not very important for most malaysian & most important is the price are cheap or reasonable.

Andy... u veli veli bad boy hahahahaha

Geezzzz i seriously need to find exhaust shop coz my extractor pecah edi need to repair... Went to Jaafar... he say need to put the car there for a day or 2 coz need to cabut the whole thingy....

Works engineering drop in air filter has got some good publicity out of this shit. LOL.

Though TS said no joke but i think it'll be quite a serious joke to say that a mere drop in air filter will make the car perform differently. LOL....
Man....vtec power? WAh...i believe it man.

vtec power? hahahaha
don't overestimate performance air filter.
And....ur saga fl got a headstart as compared to your frd's persona may be very well due to your car's lighter weight..........

bolded for lulz

lulzzz... TS, so your Saga can go over 190km/h or not???

Bro; if u read k&n or simota web; u can see that they guarantee performance increase with their drop in filter when compared to stock oem cotton; i myself can atest to that

ts is so funny. fyi, it was the campro 1.3 iafm sound which is more like a 'whining' sound in higher rpm.
as time goes by, the sound will become louder until your iafm(module) need to be replaced.
and its normal for campro auto engine to rev up to 6.5k especially when going uphill before gear change.
btw, even the campro cps cam opening does not produce any sound like vtec or nissan's n1.

put it on dyno, as in proper dyno machine instead of using your butt to dyno...


butt dyno will always give an increased power feel due to the money that you have spent...

Thats because cps only have variable lift on the intake, vtec got both on the intake and exhaust, hence the unique pranggg exhaust sound.

I reckon at least 1-2 hp increase on the dyno? LOL......
that is still improvement in performance

1 or 2hp is hard to consider improved because dyno always had static tolerance result.
to detect such a small amount u need to run 5 times on stock and run 5 times after that... so the average will tells u something... but make sure u dyno in a place that really have good air recirculation else every run they will just add the loss tolerance to it...

just my 2 cent of experience..
