You using straight flow now or still with stock exhaust? Recommend you change to 4-2-1, replace mid box and a high flow s-flow muffler.

By harsh you mean hard or the car sink down due to soft?

Environment friendly road user, do not remove catcon or change extractor. By removing catcon, you may save 1cent/km? May be after many years you finally make up the mileage to save up the amount of money you invested in a new extractor. FYI, the catcon new 1 is RM1400. U think it through why ekzos shop keep on poisoning people to remove catcon to gain more power lar. Many ekzos shop come to my import car dealers offer us RM200 to replace our newly imported VELLFIRE catcon Guess what do they have in behind their van? You're right, truck load of slightly used catcon, some absolutely looked like new.

If only changing resonator and muffler(without replacing different size of piping), that will not affect FC much, neither performance gain much. However, the right resonator(midbox) setup can help gain much on low end torque distribution(considering without changing any other part of the exhaust system, besides of the mid). Recently, swirl flow bullet is very popular, you may give it a try. It helps smoothen the evacuation of exhaust flow.



As for the muffler, depends on what kind of design you're choosing. FC wise, it will affect. The straighter, the more high end RPM(top speed) improvement, the more fuel consuming. The smaller outlet, with more baffler silence tube, the more low end RPM improvement, better fuel saving in short distance type of city/town driving.



Got 1 good, no 2 good.

When talk about cars, don't rule out anything just yet until you found the actual culprit.

1) Check tyre pressure. Reduce to 29/28 to see whether it helps?
2) To check and see whether absorber is functioning properly, get a heavier person to use palm to push the car down. Then release quickly, see whether the car bounce right up. If it does, spring no problem. On the other hand, after the car bounce up, does it sink back down and bounce like a boat in wave(up down up down). Usually if absorber is fine, the car will bounce up not more than 2 times. At most 1.5.
3) If you switch off your aircon/radio, pay attention to your steering wheel. As and when you feel harshness like hitting a small stone or uneven road, you feel sensation from your butt, you hear gruk gruk gruk feedback from steering wheel and physically you can feel which front wheel is shaking, that lower arm bushing already koyaked.

Hope this help.

Unforgettable Christmas season. Sent my son to A&E after several days of none stop purging/vomiting and fever. Finally, he was admitted to the hospital in the afternoon in Christmas eve. Later in the evening, to found my girl was having the same thing, went to A&E again in the evening. And was admitted to the hospital as well, stay right next to the brother. By the time finish everything, I made payment of deposit to hospital, the cashier wish me Happy Christmas, baru I looked at my watch, darn I missed the count down

If you notice what's happening to my rear tyres after several round of Karak run



Sorry guys, I really need to excuse myself from Speedfest. However, if the family settled already, especially if my kids discharged from hospital already, and the mother is well enough to take care of them, then only I'll be able to join as a spectator.

I apologize if this became FFK to you, but my car condition really not allowing me to risk my life. And I hate to plow into spectators incase of any unforeseen circumstances.

Hope your kids get well soon

Take care bro.

On a side note, I took the courtesy of helping u guys to understand more on what is an ANTI ROLL BAR/SWAY BAR, how and why SOME OTHER MANUFACTURER's wouldn't work.



The right way to anti sway a car, you need something in between to SWITCH the force, reverse/twist the bar. Not getting the torsion beam in a level manner.

family more important then speedfest...
may ur children recover real soon.

Sorry to hear, YAB. Hope they get well soon

Cheer up, old boy. Hope your family get well soon.

Thanks for the exhaust tip.

BTW guys I noticed the rubber seals around the 4 doors are not entirely tapped to the body. I'm thinking of getting 3m doubletape(or equivalent) to fully tape it to the body, thinking it will reduce the wind noise and external sound?
