Hi shinjite,soulfly,pacer and guys, cat-back exhaust? wowo...thats too extreme man..your car will sound like real Mini Bus. LOL wink.gif Many muscle cars use that design, it makes me look outside of my house when they pass by. I thought why so late still got mini bus 1...haha;) no offense to those members who using cat-back. Performance wise, thumbs up thumbs up. Respect for those with turbos. Sounds awesome!!

Zenden? if any of your cars can fit in Zenden 421 extractor, i say go ahead while stock lasts. Just like today, I am getting the 10th piece of extractor from kent20 to satisfy one of my customer's demand for extractor while the other 9 customers are very satisfied with the stuff. Dont worry that you will lose little of your low end power, you will gain a lot in middle end and high end. The power kicks in around 3k-4krpm if you're using stock exhaust system for manual cars. Change your s-flow muffler to straight flow to gain back your low end power. For nice solid sound, of coz' get Monza or FGK(Fujitsubo) and better exhaust flow. Get bullet to replace your stock midbox. Thats the best out of your exhaust system with a final touch on your pipings. oooOOooo...JUst my RM0.01 from my pocket anyway smile.gif Look for me if you need any stuff..giving u all best price la..( sorry coz doing some promotions here, LOL:) )

Twin Loop? Mugen imitation ..price about RM500 with installation...Pics below:
MUGEN TWIN LOOP (IMITATION)
MUGEN TWIN LOOP 2

Effect: Top End power and creates sufficient back pressure for auto cars especially with vtec.

*of coz if got money, get the original one...hmm...

howie: still cant decide ar..i understand what u worrying about...anyway, i guess the best exhaust for stock 660 manual is using single exhaust path with 1.6" piping and straight flow muffler...since ur air intake is open pod(air sucked faster), it will be great if ur outflow is done as well...else, it will be like dragon got head but no tail...

soulfly: howie has done a lot on his car , i guess he wont be selling that car but only buy a new car...his kancil is a rare species with self-tuned ICE system...hehe:) maybe gf drives that kancil and he buy a monster car biggrin.gif

I change my exhaust system.
However still feel low pick-up power.
So I wanted to change the air filter to improve performance.
Any idea?
My car is 1.5 Wira manual.
4-2-1 ext with midbox,1.7" piping and straight-muffler.
Pls advice!

exhaust no problem wor bro..ur pick up should have improved... if stock air intake, then i suggest go for open pod with nice CAI setup ...ELSE, go for drop in, no need pening kepala... just my 2 cents..

sonic_darkknight: what is ur budget? and how much you pay for a whole system of WISE include installation? if 2nd hand, how long it has been used? Well, if WiSE whole system fits nicely to you iswara and it is cheaper than 400 bucks, i say go ahead. However, as far as i know, the ori piping route of WiSE is different from iswara piping route but the extractor should fit nicely. Need to check it out. Let me know k?

hi forummers,

can i ask for advise also?my car is iswara a/b manual 4g13p.seems like more reading leads me to more confusion.already running on cap ayam 4-2-1.dont quite feel the difference.my concern is pickup power so i can use higher gear at low speed,also to ease hill climbing.whats the best exhaust setup for my car?is it possible to have lower fc with certain setup?same fc is ok but let the new setup not increase my fc.

*cap ayam 421 extractor


Bro, myself is a 4g13p aeroback iswara owner. So, if u would like to gain on pick up, it's simple.

1.EXTRACTOR 421
2.THROW AWAY ORIGINAL MIDBOX , REPLACE IT WITH A NEW BULLET/MIDBOX(2" will do)
3.CHANGE YOUR STOCK SFLOW MUFFLER TO STRAIGHT FLOW,(I RECOMMEND MONZA BIG SIZE..SOUNDS LOW BASS AND QUIET IF U R USING THE MIDBOX I RECOMMEND)
4.1.7" FULL PIPING/ SEMI PIPING...BOTH GIVES U DIFFERENT FEELING WHEN DRIVING..

*FC is depends on ur right foot..as long as your setup is correct and no wrong way of modding, it should give u better FC becoz restriction is less and negative backpressure for your manual tranny increases fuel efficiency...

Now that i've removed the kucing from my exhaust, i plan to install a 4-2-1 exhaust header in the future. The question is, do i need to change the whole piping to complement the new header?
*
It is not compulsory. Changing the whole piping to a bigger inlet size will smoothen ur ride in high ends. But, it also depends to the end muffler u r using. If u r using straight flow, it is recommended to change ur piping size as well.

You mean by changing the header or the piping that might affects the fc? The header that i wanted is the one from powerzone smile.gif

nah.. i dont think he means that..but headers depend on individuals. Everyone's driving style isn't the same, u might wanna rev until 3krpm and shifts...but some will like to revv till 6krpm and shifts...So, the power needed at different rpm band needs different header designs.

Piping won't really affect your FC if you mod the piping to bigger size but remain in the correct range of inlet size. Try not getting sizes which is not suitable and my opinion would be changing to +15% would be the best. However, if you've modded the system to TOTAL straight flow, then, i would think it is compulsory for you to go for bigger piping but not too big like i have mentioned, this is to increase your HP or top speed. Like wise, if you're on SFLOW setup(swirling bullet/sflow muffler/4-1 extractor), i would say NO to piping size increment. Just my 2 cents afterall biggrin.gif

what is the best setup for kancil 660?

If change 3-1 extractor have any effect?

Bro, stock design is already 3-1. However, changing to a bigger inlet one will help in better pick up power.
