Not to say as hard as possible la, just hard enough for ur car to slow down as fast as possible, but not hard enough o lock ur tyres.

My exhaust sound no metal noise la.

Yeah u can change the mid and rear first.. Like me.. XD.. My setup is 1 12" swirling wegow bullet, 9" straight flow insulated secondary bullet, and probably Greddy Racing Ti-C s-flow muffler / FGK fujitsubo..

Brake as hard as possible without locking the tires..

Huh? Budget 500? I need u to tell me what exactly u need... Then I'll see what I can do to make the most out of ur RM 500..

If u just want a good noise out of ur car, go change Mugen's Looped VTEC muffler.. At first I wanted that exhaust, but think think dont want lah.. Cos I wanna stay low profile.. But it sounds REALLY nice.. Eargasm...

Honestly speaking, I'm a performance & ICE oriented person, not so much on aesthetics. So yes, a replaced muffler will sound louder & nicer, but doesn't give much improvements to the car's performance. U might gain a little bit on the top end. Just a wee bit, probably negligible.

4-2-1, swirling bullet, midbox & s-flow gives best performance, but u'll get a bit metal noise due to the thin wall of swirling bullet. Piping remain stock.

That's the whole exhaust system already yes, s-flow is the muffler. As for brand, if ur budget limits u then u can go for those ayam brand stuffs. Piping remain stock.

For RM500 and u want to change the mid and rear only.. Go for 1 12" swirl bullet (will have some tin sound effect when accelerating only, cruising time wont have sound), 1 midbox as resonator to help reduce the sound and 1 s-flow muffler to improve back pressure and increase top speed.. swirl bullet goes for around 180, midbox 150, s-flow a good one around 250, total 580 loh..

Pick or no pick also have to pay ma.. So since u're paying already why not just go n choose, rite?

Yup. That's true.
If you din pick any number, it's free..
usually I pick the number self by travelling to wangsa maju JPJ and choose the number

Need to. U're still paying JPJ RM 250 for the registration. And u're allowed to choose ur own number, or take random number at ur will. Of cos, don't talk about those VIP or highly sought after numbers lah, those definitely u need to pay extra or tender earlier.
U tell ur SA u go JPJ to pick urself. The RM 300 ur SA is charging u is runner's fees. If u wanna choose nice numbers like Wxx 238, 338, 888, 8888 all the cliché nice numbers, u will have to pay them extra.

Well...if your SA provides good service, he could help you to avoid unwanted no. (such as 4) for free...but u will get random no.s lo...if you are not particular and want to save 300

If you choose current number like 5xxx it's cheaper
If you want jump number like to 9xxx you need to pay more.. forget how much already..
That one it's included for buying car ma..
Just number only you need to pay again..
I thought they charge because need pay JPJ for the number and runner fee is only RM 10.. 

That means they're getting into a new cycle. Go get the documents ready n go straight to JPJ to get ur number now. If u're lucky u might be able to get what number u want AND save that RM 300.

Perhaps when u asked him the number was still on the previous cycle. U can still get 3 digit plate now if u want, but only the rejects, and I guess by now it should've entered the 1xxx mark already. If u want ur 7xxx number, go to the counter n tell them. U have to pay RM 50-100 extra if I'm not mistaken.

He outdated already izit?
Or the number you give him dont have already?

There are no Is, Os & Zs in our plates. Zs are reserved for the army.

Should be the previous one.
Didn't buy but come out straight number damn sakit wan leh..
2 months? My car is WUP, registered in November, & it's WVJ now. If 2 months is how long it takes to complete a circle, we wouldn't be past WUS by now.

Bunch of crap ur SA makes up to earn a bit extra. U can get a number that u want before the current cycle actually reach that number, but provided that it's of the same cycle, and u pay that little bit extra.

Wth? need wait 2months but now WVJ?
When he told you that and which SA you went?
Special tak sakit sangat.. 
Some agent really tak boleh tahan one.. 

Go jpj take a picture of the running number on the e-board then show it to him. WVH my a**.

Oh.. if that number you then ok..
If dont want, just kasi marah only..
It happen to my SA, but different thing.

Meet who? Ur SA?
