To me, I really hate twisted bullet. By looking at the swirl flow it create alot of restriction. Come to think of the purpose to remove cat-con, we're taking away the restriction part right? Why add another restiction bullet?

So I suggest u to look for straight flow bullet. If u changed the 4-2-1 and de-cat, ur rear muffler will give an annoying metal sounds during revving. By the way, ur's is campro or 4G18?


i using 4g18 AT bro...so is better to use straight flow bullet replace catalytic converter than twisted bullet?

and is it for sure my muffler will have some metal sound?even if i change to aftermarket s-flow muffler?

alright bro...TOPCAT brand?what brand is it bro?any link to the brand or what?if i using back my ori wja muffler at the moment can right?

bro you mean TB also need ground cable ah?direct grom -ve battery or from firewall is better?

Alright bro...and i found my waja got stock ground cable connect from firewall to TB,if i change to aftermarket gound cable which is thicker abit will be better?

What mean by best grounding wire silver wires bro?how much normally will cost?just install myself can?

Ok bro,but how much will cost for 1/2 meter?and 1/2 meter is just one point only?just to connect -ve to TB a?

yup there is already one ground cable connected to the intake manifold,can i just get another good grounding cable and install together with the existing cable?mean two grounding on intake manifold?

OK,so where else can i ground to bro?can you guide me?or who have the diagram or photos can share with me where to connect these grounding cable?

thanks!

Just installed my 4-2-1 extractor and zenden twister bullet because was recommended by them for my waja 4g18 auto tranny...

is it true we need to let the ecu re-calibrate the system again after we have changed the extractor or touch the o2 sensor?

because after install i didn't feel any different...and claimed by them need drive and let ecu re-calibrate again right?

And regarding the bullet in pic below,which side should receive exhaust gases and which one is letting it out?

the one below is smooth side...they put it as the gases out,and inlet for exhaust in is opposite it..mean quite restriction right?

bro i did it rm250 included installation...

radiator fan only work when our car temperature reach 80-90c...to cool down our car temperature...if your radiator fan isn't working all the time you will realize your car temperature will keep increase lo..sifus here please correct me if wrong ya!hehe...

Oic..hehe..but just feel a little improvement only..lol..yup 250 is for 4-2-1 extractor and zenden twister bullet to replace my cat-con..done at kepong waiheng..they claimed that their extractor all are made from mandrel bend machine,and said by the boss too..

nono i stay wangsa maju...bought zenden bullet and extractor with ken20(the one selling in marketplace zerotohundred) and go there with him...the shop is near carrefour..

and about the everco midbox do you have details about it?hehe..

i also noob about exhaust thingy..haha...waja stock got midbox also after the cat-con,the one bullet i change is to replace the cat-con..mean still got another stock midbox there..hehe

Halo any waja owner here..mind answer my question?hehe

Is it recommended to re-set ecu by taking out the -ve battery terminal and install back after we have changed to aftermarket 4-2-1 extractor?because o2sensor have relocated?

is it necessary to do so?or just drive and let the ecu re-learn it back?

my car 4g18 year 2002 at...hehe

hope to get the answer here....

ok..so our ecu will self re-learn back a?just drive as usual right?

oh..alright bro!thanks!

Bro what ecu does waja 4g18 year2002 using?

and it is self-learn type?

my meter stated there vdo,is it vdo ecu?

what the difference between vdo ans mitsu ecu?

alright..will try to take a look later!hehe...

budget constraint and non avaiability of 3rd party parts (no supplier for OEM parts)

proton quoted ridiculous prices, so i planned to smoke my headlamps

the 5-button costs about rm250, which price i think is unjustifiable for a simple thing

the gated shift is rm600+ - didn't get it too since i am savin gmoneuy for LED tail lamps (aka m5 style?)
from my previous exp of burnt ECU, proton says there is only 2 ECU available - the Mitsubishi (for 4g18p engines) and Siemens (for campro s4hbla bla bla engine)

yeahh.. at the moment, the cps part r to high.. nyway i just install cps starter, just very nice sound while start..
very like it...

[/quote]

haha how much you change to cps starter bro?including installation price?

beside from different sound,still got different cps starter compared to waja 4g18 one?what the sound?so nice ka?hehe..
