Yup. I wait until the indicator move up..

My S-Flow Muffler

...I thought seat belt should be fastened at ALL TIMES when u're driving? No wonder we can see so many superman cases on ondscene...
Have u been secretly modding ur car without telling us?

The jerking, it happens only during cold start rite?

I feel for myself that:
(1) PE M Line (Auto) brake is really not makan. Is this case for all PE?
    Anyone with M Line Auto with powerful brake (without midify)?
(2) The light at the meter, is it always ON all the time?
(3) Can hear the 'metal sound' coming fr the backseat on uneven road.
(4) The tire pressure fr factory is really powerful, +/-40psi.
And finally,
(5) I heard a "English speaking lady's voice" coming fr inside the car, where did she come fr?

It happen to me three days morning already..
Tomorrow morning will test again..

Thanks bro. 
Got improve. I change full exhaust system. I am using auto. 6.5k rpm switch gear. Can feel pickup increase a lot.

If he can record it and still don't know where it came from, this is a job for Ghostbusters. 
Be careful now that it is near Ghost Festival. 

Is there any female voiced Transformer?

Ok la. long term investment ma. Yeah adding mid box will further reduce the sound. Mine long term just a bit louder than stock sound lo. LOL

That is hard to record bro. After 3k rpm i only hear engine sound. LOL 

Yup. 6days more my car officially 2years old

better make sure everything is OK..... mine damm FCUK.. cause ngam ngam 2 years.. IAFM rosak and the power stering got sound.. manage claim power sterring ... but IAFM... GG

Mine is Apexi S-flow muffler. I think the price is RM350. i am not sure cos the seller quote me full exhaust system. LOL

My car will be 3 years old 10 more days.
just sent my car to SC to claim for IAFM. 

I got snap. need to dig out in my phone.  My service coming soon. Will take a clear photos of all my modding stuffs.

Yeah i use D drive and full throttle can go to 6.5k for 1st and 2nd gear.

my one cannot lo even full throttle..will change once hit 6.1k rpm..fast dig out from ur phone,wanna knw ur mid setup lo..my one bullet and midbox distance onli around 4inch..is it can cause the sound more louder?

My uncle's S-class got alarm warning sound everytime he drive past a speed limit sign.

Cornering it depends.. Certain corner especially the flyover will have rubber in middle of the each road which joints the road.. when u make corner and u pass by the rubber (black color), there will be slight shake and ur car will bump a bit. At this point u feel its not smooth...

If no rubber and make a corner, it definitely will smooth... max i made corner so far was 80km/h which the corner a but sharp also..

I agree with you. Its just made for stylish....

Itu manual lah.. ppl talking bout auto here.. 
If u were to turbocharged ur car, u can actually maintain ur FC around the same region but increase hp.. But when u install high cam in ur car.. Straightaway say bye bye to ur FC... There is no such thing as good FC and high powered NA engine.. In NA engines u either choose low end torque or high end power.. In turbo charged cars u can use staged boost setup.. So u can have low end boost with VGT or BBT and extra boost when u reach the high end part.

The tech talk was about piston compression.. NA must use high comp to get high power.. Turbocharged must use low comp, or not engine will knock or blow.. With NA engine and high cam MUST use RON97 or higher.. Turbocharged can still use RON95..
GSR terbalik can.. But nowadays GSR and Mivec engines all around 10-15years old ady.. No point getting those engines.. The tech is too old and not efficient anymore..
huh? facing which way? what u mean?
But u get an old engine, unknown mileage, and lots of hidden 'goodies'... I personally favour getting a good car with a good base engine and mod it off from there.. Furthermore nowadays GSR and Mivec CK engines are getting more and more expensive ady.. in 2002 u can get a GSR terbalik 1.8 for only RM3k. Now the same engine with higher mileage is going for around 8-10k at least.. not including installation..
Nope no chance of better FC.. when u install high cam ur low end speed will have very high FC.. around 1.5-2L/100km higher..
True also.. Campro engines are long stroke.. meant for turbocharging more than NA.. Efficient NA engines with high horsepower are not long stroke engines.. For example K20A and F20C engines.. they have bigger bore than stroke ratio.. and they have high horsepower per litre >100bhp:1000cc.. Long stroke engines are suited for turbo application more like RB26DETT, GSR 1.8T etc. U can see that these engines are very durable as the longer stroke helps to clear more vacuum in the combustion chamber for a longer period, allowing the air and fuel to mix more evenly b4 combustion.. and there are alot more other stuffs as well..
BOT got anti-lag system now mah.. Nowadays continental car boost kicks in at around 1.8k-2k RPM.. Full boost by 3k RPM and the full boost of around 1bar can hold on till the end of the rev.. In msia all those kucing kucing modders pakai GSR 1.8T, Mivec CK kind of engines where got good and effecient? those are considered the 2nd generation of turbocharged engines only.. Nowadays turbo engines are at their 5th evolution process ady..
