yeps , still using the oem 4-1 extractor and i dont think i'll replace it with 4-2-1 , maybe a tuned length of 4-1 from everco instead.

btw , muffler aint going to make any differences other than sound , right ?

seriously , my brother waja accelerator is very torquey , i check his car , engine all stock except mid section of piping changed.  *clueless
maybe inside the ecu tuned by dk tuning ?  btw , it's a 2nd hand car.

can please share how much did the tuning cost u?

Our radiator + reserve tank could use as much as 8L to 9L.
1 bottle of 1L coolant is not enough - at all to prevent rust.

To get 50 : 50 ratio , you need at least 4 bottle. 1 bottle of Motul Inugel easily set you for Rm50++ x 4 , you do the math.
Even our brother "sleepwalker" here are using 3 bottles of Inugel only.

It might be expensive to use 3 bottles , but changing coolant is every 10k. so it's still cheaper than changing engine oil. 

and btw , those coolant with Anti-freeze is not the best to use in a hot climate country like malaysia.
elton : what does danny mean by throttle cable ? the throttle cable getting lose ?

at doridori i did the following..
- 2nd hand 4-2-1 extractor from dori2 - rm150 (traded in old oem extractor)
- throttle body service - rm20
- prorallye plug cable - rm160
- ultraracing metalflow performance air filter - 160
- remove catcon n put in straight piping - rm20
- pdt tuning - rm40
- repair steering rack bush - rm50

at waiheng 
new sflow muffler - 250

sure looks like all those cost alot compare to 'flashing' but i believe my waja is ready to be flashed now instead of doing the flashing while still being in stock mode that has restrictions to the input and output of the engine..

now if only i have the $$$$ to go to steven.. 

my waja is auto so a good sflow muffler helps maintain the backpressure..

very torquey? happens to my waja too before any mods..
it is set by the ecu and changes according to how the driver drives the waja..
so its not a permanent thing.. all the 'torqness' will be lost if some one drives his waja slow for a couple of days or disconnect the battery for a few minutes.. it happened to me and the fun of driving waja was gone..

last week made some mods on the exhaust system and intake system..
now i just drive slow but the torque is there ready for use when needed..
i can feel the car jump at the slightest touch of my pedal during start stop.. 

ps - my waja is tuned by shaiful dori dori autoworks..

Me also by Shaiful..but last time at TRIAL..

I guess most of guy here have the same set-up as you , except 4-2-1 or maybe remove cat-con. more or less.

btw , the price for the pro rally plug cable really cheap there. 

after no more pus*y , feel the need to invest in good muffler to have the low rumble idling sound and loud sound when revving.  the original muffler is just too silent!

I afraid you will regret for loud muffler like me last time cos feel annoying after sometime

in my case when changing the extractor n killing the cat, my oem muffler sound like preng preng preng sound..
like c70 kapchai like that.. so funny, ppl laught hearing it!
so i had to change my oem muffler..

the waiheng muffler is good enuff n cheap..
when idling its not producing any sound like oem..
when normal driving got a small hint of bass and i consider almost as quiet as oem muffler...
when revving high rpms its bassy and not loud at all for me..
i've seen my share of loud exhaust setups and my new muffler is still considered quiet..
100% confident wont fail any jpj roadblock.. i love it!

you use loud exhaust before this? mind share what brand and how much you got it? heard that tanabe medallion sflow or mugen twin loop is not bad at all..

I assume you're talking bout the imitation twin loop and I will suggest you to avoid it
a friend of mine is using it and he said that it produces too much back-pressure, producing not enough flow thus causing the car to lose at top end

I would love to replace my exhaust to a better ones but i really concern about the sound. I spend more than 20k on the sound system and i hope the exhaust dosent spoil the sound! What i heard from elton, everco is quiet but im not sure yet! i have to ask around 1st!

one thing with everco ..before i change to everco..my cap ayam system produce petrol smell..everco said is running too rich..now with everco the exhaust smell no more petrol smell but super smelly..
