Buddy , could you get the grounding cables for us and sell it at a higher price ? With a little higher price to pay , we save the hassle and the chances of getting not-so-good and wrong wire.

Oh yea , I would like to ask does our original exhaust system comes with mid box ? I guess there's no midbox right ? I'm intended to replaced my cat-con with hotbits midbox but they said it's impossible to fit into the oem exhaust/piping and recommend to replaced the whole set-up at one go around @ 1.3k. Since they said replacing the extractor will remove the Cat-con aswell , I'm in a dilemma on which to change first.

anyone mind sharing pics of their waja engine bay with grounding done? and also wanna ask k&n drop in filters are not white in colour right? cos im not sure if my car is stock from the previous owner.

hahaha.....give me sometime (during raya holiday) to get 1 grounding wire for myself then i'll share the photo here.

Standard exhaust system comes with straight flow bullet. U can install midbox if ur rear muffler are extremely noisy.

Not necessary to get hotbits midbox, u can either get Improve bullet or Topcat bullet / midbox. And don't spent too much on bullet / midbox as it only serve to reduce the noise. In fact they can cut and weld the hotbits midbox to ur standard piping and I guess they're just trying to push the complete system to u.

ooh thanks for the pics. i think mine's still stock. ive got around 200 bucks to spend. would u guys recommend me to change air filter or get a VS and do grounding? both cost around that price rite?

Do update us when you got the grounding wire. For the Hot bits Mid-section ( should be mid box ) , they're selling it at Rm314 while Topcat midbox selling around Rm250 with installation. I guess it's better to go for Hotbits right ?

I think the best bang for performance would be Replacing the cat-converter with a Midbox/bullet or change the extractor to 4-2-1 type.
If you doesnt want to replace the cat-con yet , then get a K&N filter which cost you around Rm275.

4g18 waja dun have traction control right?
i just buang my waja yesterday, luckily nothing happen, just the wheel hit on the divider and kemek.

how much would it cost to replace cat con bro? mines a manual...so which would be better? im basically looking for more power at high rpm. im a real noob at exhaust systems..for so long i still dun understand s-flow and bullet and all their functions and differences. sorry!

No traction control, ABS, EBD, Airbag and whatsoever safety features. it is just a basic car. Unless you are driving the 4g18 premium which only has ABS and airbag.

I intend to do some MOD on my waja, which will make the FC better.. Any suggestion on what should i modifiy or add in particular accessories?
My suggestion from my fren is to add a Volt Stabilizer and change the extrator to 421... Btw, my 4g18 2004 waja is 100% original...nerver modify anything before from the previous owner...

Topcat midbox = RM250? that's way too expensive. Should not more then RM170.

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?

Everco should have increased their price then , Mr.Kingston over there quote me around Rm210 for it and around Rm250 complete with installation.
I do even ask them if they have anything better than that mid-box that he offer me and he told me that there's full stainless steel one. He doesn't recommend it to me though as I told him that I'm still a student. Thumbs up for his explaination and services.
Get back into reality , do you think I should go for Topcat mid-box or Hotbits mid-box yea ? As everyone know , both of them is quite reputable and Hotbits is the one who dyno-tuned their product before mass-production.

Lots of you guys asking whether VS will increase performance or not and from what I read , it's either no improvement at all or only slight improvement. Do this modification when you have the spare cash.

Better FC?

- Constantly check & maintain your tire pressure. Always ensure it's at it's optimum pressure.
- discreet driving. No sudden quick acceleration & cruise driving all the time.
- reduce vehicle weight. remove items or rubbish which are taking the load of the car. Skimming on the weight can reduce the load on the engine.
- if you still have cash, spend it on lighter rims or campulley.

bro so u mean u'd recommend me to replace cat con first instead of getting the new air filter? would it cost more than 300 plus workmanship? replacing cat con doesnt mean i'll get those loud exhaust noises right?

Besides that
- Using a Synthetic or Semi-Synthetic Oil
- Better Sparks with good spark plug

Everyone here will recommend to replace the cat-con first as it restrict alot of flows in your exhaust system. Removing it will definitely increate your noise level in your exhaust but by installing a Mid box , it should balance that back with a little or no increase in decibels.

As mentioned few post back , I was quoted Rm250 for the mid box with installation in Everco , maybe you should drop by and negotiate with them.

oh ok. thanks issit true for manual its better to get the midbox instead of the bullet? Everco is in sunway right?

u will get slightly noisier from ur exhaust as the air is flowing fast by now.
