Guys,currently my 4G13 is using the stock exhaust system.Is it recommended to change just the extractor to 4-2-1 and the stock iswara muffler to S-flow type without changing the piping? BTW,what's the inches is the piping? One of the shop recommended me to put the bullet with swirl one. He claim that it would have a better pick up and FC improve. Is it true? I read most of the people replied here that the swirl bullet inside the hole will decrease the top speed.

If just change the extractor alone will increase hp abit?

wanna ask muffler got lifetime or not 1? need to service it ar?

but then izit recommended to put the swirl bullet?   I read past the last few pages some forumer said not good on their myvi but saga i dont know.Willing to learn more.BTW,the stock piping how many inches?

my mech told me, says that the joint between the 4-2 and the 2-1 header is leaking; would it contribute to power loss?

whats the difference btw 4-2-1 and 4-1.

dei cata, why is the material so different?

trying to promote 4-1 ar?

yea i know the shape, but what is function isit 4-1 better pickup or 4-2-1 better top speed?

hehe recap abit mah, paiseh... 

Coz im going to chop the 4-2-1 shorter...  for pickup sake...

hope this is the place to ask.. i'm looking for my first performance mod on my 4g13 satria (manual, injection)..  guessing i should start with exhaust and intake.. should i go for open pod or drop in?

and how much is the powerzone 4-2-1 extractor for 4g13/5?

low rev, now is still lagging, campro. 

its lagging not due to the exhaust system...
its the DRIVE BY WIRED system...

@_@!

luckily i haven't cut yet, the jian hang keep blame my extractor is too long...

guys i got question to ask,

my 4-1 extractor o2 sensor is below the 4 piping (near nenas)...n other extractor i see their 4 piping is small than me and their o2 sensor is hooked on one piping...what is it means?

and what's the difference between stainless steel n steels? is it for 'bling bling' purpose only ?

1. other extractor i see their 4 piping is small than me

2. what's the difference between stainless steel n steels?

3. usually what brand of extractor that using o2 sensor hooked on main piping?

thanks for the reply...

1. it's a question why others extractor piping is small than me?

2. then no need to wrap it if mine is stainless steel?

3. gen2 

any difference between chrome and non-chrome?

Oh gee Capt Obvious.. even you can do better than that..

Header wrap can cause the metal to become brittle and break like biscuit.
This guy really johnkor?
Looks nicer,prevents corrosion..but my friends chrome header now looks gold...weird,maybe the plating too thin..

Shiny surfaces reflect heat,not sure it this has any effect on the outside of the header but maybe chromed inside might be good for turbo applications?..

catabombs - but i heard ceramic coating will damage ur o2 sensor rite? ^o)

i mean it will read readings wrongly?

is it advisable to do a powerzone full exhaust setup at eneos one utama?
seems thats the only dealer powerzone has around PJ, so just wondering on the eneos workmanship there.

nono... dont get me wrong.

i got this information from other ppl also..

hmm.. i heard it damages the o2 sensor.
thats all.
