Nope. It was morning, early in the morning like 6 plus. I left early cos I thought just nice will reach there at 10. Mana tau 1 & 1/2 hour sampai d sweat.gif
Increase horsepower. Actually, if u can find a way to channel fresh outside air directly in front of the open pod air filter, ur top speed wont drop. The reason top speed drop is because air flow not optimized.
632grams to be exact. It's a myth that 4-1 can only be used for manual cars. If u understand how 4-1 works, then u'll understand why i say this.

The reason why 4-1 is not recommended for auto transmission cars is because ur low end torque will suffer. On auto cars, all we want to improve is the low end torque. As for manual cars, u're free to shift ur gear at whatever RPM u like, and there are 5 gears to play with. And also, with the catcon removed, there are much less restriction and this change can be instantly felt in manual cars. That is why the torque loss is not so noticeable. As for top end, both auto and manual benefits from it due to the design of the extractor. For auto cars, the loss in low end will cause the RPM to climb much more slower to 3-4K RPM, then from there the pickup will kick in.

Our stock exhaust setup is 4-catcon-1. Which is indirectly a 4-1 system as well. There is another way if u wan cheap performance: remove the catcon from the stock extractor and connect it to the rest of the system with extra pipings. Cheap (costs only around RM 50-80 for workmanship + pipe), quiet (everything else stock, slightly, VERY VERY slightly louder than stock due to increased flow), and hassle free (u can always keep the catcon & plug it back in case u dun feel like damaging the environment further).

Also, did any of u guys know that the cat-con is basically useless after 100k KMs? Means u're actually supposed to replace the catcon every 100k KMs, and it's not cheap. The elements in cat-con that converts the CO to CO2 will eventually be burnt till nothing left, and then u'll have to replace it in order to further 'conserve' the environment. By right u wouldn't die from CO poisoning if u plug a tube to ur exhaust tip and pull it into the car, then lock urself in it with the engine running (PROVIDED THAT UR CATCON IS WORKING, DONT TRY THIS AT HOME). Not to say that u wont die, u WILL eventually die (provided that ur car is airtight) from oxygen deprivation, but not CO poisoning.

Also to add, the catalytic converter lifespan will shorten from long period of idling due to overheating. Just another point for u environment-lover guys to take note.

I dun quite recommend installing LCP before doing exhaust mods. The power loss is very slightly only lah, but if aftermarket exhaust is installed u wont feel this..

Paint yourself lar using touchup paint. Bumper is not metal, so won't karat. I also scratch front bumper on the lower side, have to use touchup paint....mmm...what brand is it...got it from Giant and the paint is the exact color code for my silver. Also gotten City alabaster city and black pearl exact code for that. General silver sure different color but touch-up paint with exact color code normally quite similar.

if kena body which is metal element, touch-up paint can work? i got 15cm scar on my car body... sad.gif

if kena metal then better u use sand paper kosok the scar 1st... removed the rusted area then only apply paint.
if u terus apply paint on it, i'm afraid after some time if it rusted even worst will become bullet hole shocking.gif

think to send to paint shop to repaint it...

If the cut is very deep and you have the dough, you can repaint thru workshop. If your scratch is at door, chances are you have to paint whole door, abd RM200-300 or so. Since new car, paint door straight, if older car with slightly faded paint, have to paint BOTH the door and part of front/back side body to maintain same color look.

Note that the sealent they use (gold oil in chinese) can be of multiple quality. Some ppl quote cheap cheap, of course gold oil use cheap cheap wan. There're gold oil that cost RM50 and there's some that cost RM200...don't know how to differentiate but supposedly good oil will keep paint vibrant and protected for long time and won't fade out. That is besides the cost of 2K paint.

kena at back side... near the petrol cap there...
