Hi everyone at lowyat.net,

My name is Jonathan or nickname John and I live at KL Cheras, this is my first time post at lowyat.net although I been observe lowyat.net for many year until now.

Currently I owning a Proton Saga CVT 1.3 (E) from last year October, I choose Saga over Myvi because CVT, handling and larger trunk if someone ask, and I don't had any bad complains about this car accept performance and quality, you get what you pay .

P/S: I'm a aggressive driver.

Is been 6 month and my car almost reach 10k (odometer),  I'm thinking of upgrade/modify of my car and I had two option to choose:
First option:

1. All available product for Saga FLX (accept Room Bar) from Ultra Racing.

2. 15" rims with 195/50/R15 tyres.

4. ECU tuning, remove speed limit and improve FC.

3. Aftermarket high flow stock replacement air filters for Saga FLX.

5. Aftermarket high quality or braided stainless steel brake hoses.

6. Aftermarket Rear skirt diffuser.

7. Aftermarket 4-2-1 exhaust manifold with ceramic coating, keep stock catalytic.

8. Aftermarket S-flow muffler.
Second option:

1. All available product for Saga FLX (accept Room Bar) from Ultra Racing.

2. 15" rims with 195/50/R15 tyres.

4. ECU tuning, remove speed limit and improve FC.

3. Aftermarket high flow stock replacement air filters for Saga FLX.

5. Aftermarket high quality or braided stainless steel brake hoses.

6. Aftermarket Rear skirt diffuser.

7. Aftermarket 4-1 exhaust manifold with ceramic coating or stock exhaust manifold, keep stock catalytic.

8. Aftermarket Hi-flow muffler.
Optional:

Upgrade rear brake drum to brake disc.
Basically the differences of the first option and second option is exhaust system (6. & 7.), I need advice from lowyat.net Guru to know what are the pro and con from these upgrade/modify option and which aftermarket brands and what shops to get these upgrade/modify.

Thanks to anyone who read or reply this post.

Hm, I thought ECU tuning can make sense, since the factory setting should be meant for poor fuel quality. It can be tweaked for better fuel, and will give more power and/or better fuel consumption, at the cost of not being able to drive on low quality fuel.

Though it may not make much sense in Malaysia... our fuel may not be that good...

    wrong la bro

If RON 97 is 97% gasoline + 3% Pentane, then RON 102 or RON -30 is what

RON grade is a number assigned to a fuel according to it's tolerance of compression before detonation, eg. Diesel detonates easier than petrol and hence has a lower RON number than petrol.

It does not denote the % of chemicals inside the fuel.
