Warranty only void for the extractor lah.. Dont say u change extractor they go void the whole car warranty.


Btw for TS, some advise for u as we Personarians have been experiencing with so far (same case for saga FL cos the engine are technically the same)

1) modding the extractor ONLY voids the extractor part. Wont void the whole engine.
2) If want to claim warranty go to COSE. Damn easy to claim even if u mod ur car.. Install 17" rims also can claim for replacement discbrakes. XD
3) U want more low end torque go for Hotbits. U want high end power go for Powerzone. Hotbits the pipe diameter are smaller => faster gas flow => better low end torque. But top end power will be somewhat restricted compared to Powerzone. Powerzone extractor does not improve pick up much. Marginal increase, but top speed increases alot.. We are talking of reaching 220kmh here in Persona 1.6 IAFM with light mods.
4) IF and ONLY IF u have 4k lah.. Mb ur budget lesser, I can list the stuffs to upgrade in the following order.
1) Denso 0.4mm Spark plug
2) Works Engineering Drop-in Air filter
3) Grounding cable (VS barely gives u much improvements except smoother shifts at high speed)
4) Full exhaust set up. Extractor first if u dont have the budget. Then 2 swirl bullet or 1 swirl + 1 mid box followed by S-flow.
5) lightened crank pulley
6) lightened cam pulley

For engine maintenance
1) Caltex Havoline / Castrol Edge / Castrol Magnatec. Please dont use Shell Helix Ultra/HX7 .
2) AMSoil ATF
3) The correct brand of petrol. For best power Caltex > Esso > BHP > Petronas(this was tested with old Primax, the new Xtra fuel has not been tested yet). Shell cannot pakai at all. For best FC Petronas Xtra > Caltex > Esso > BHP.

These are all tried and tested by LYNPPC members as we all become white mouse and test different setup for best FC and performance. XD
LYNPPC - We kinda spam quite a lot there.

Ori exhaust are restricted to comply with emission standards imposed. Restriction do reduce power, but with lesser power, higher acceleration is needed to speed up and higher amount of throttle opening is required to reach the speed intended. With better flowing exhaust, more power is produced at the same speed, so lesser acceleration is needed to maintain speed while cruising. Just my 1ringgit 90cents of opinion.

Nvm.. Knowledge is power, just sharing what i learnt here..

Btw one of our forumer went to Kweng's shop in Wangsa Maju, VERY bad experience. It shows that the shop knows nothing about the basic principles of exhaust. He went to change extractor due to raving reviews and the reputation of Kweng, on the extractor the o2 sensor is located AFTER the nanas, and the nanas is triple insulated. Since persona o2 sensor is not the preheated type, the car was terrible and acceleration was literally zero. U could floor the gas pedal and the car would just continue at its own pace without and acceleration..

haiz dont lah so butthurt.. Pay cheap things for low prices doesnt means that they can simply do shoddy work on ur car right?
I pay RM280 for steel exhaust doesnt means they can drop a nut in ur engine mah.. I wont expect the exhaust to be worth RM280 or more. But at least i expect a decent service where they installed it and give it back in usable condition.
Is it that if u pay RM500 for extractor then only the mechanic must hold the nuts somewhere safe and dont simply put in meh? Sarcastic hypokrit..

THanks.. Im sure both of u are enjoying the plugs and filter..

for apple to apple comparison.. Hotbits extractor only vs Powerzone, Hotbits primary pipe has a smaller diameter to increase exhaust velocity producing the vacuum and scavenging effect on the intake valve, therefore drawing more fresh air and fuel into the combustion chamber to produce more power. However when u reach high rpm the air velocity out of the exhaust valve is high and the smaller diameter hotbits primary becomes a restriction to maintain gas flow.. However powerzone primary tube are bigger in diameter.. In effect low end torque isnt really much improve due to the primary pipe not playing a major role in scavenging, and it solely relies on the secondary tube to create the drawing effect.

As what samwongjyhhorng has mentioned. We LYNPPC did a TT session racing up genting and back down to kl last saturday. It has been proven that hotbits did have a restrictive effect on top speed but providing much better acceleration instead.

Wegow is cap malaysia one.. But the quality seems good.. Too bad its not available easily.

LOL.. U want top end power?

Added on April 11, 2011, 10:09 pmNo lah.. we didnt change to hotbits cos it looks better lah.. We are trying to compensate more for the Campro's poor low end torque.. At high end there we got enough power to tapau the Myvi's and vios'es on the road..
