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?

change abit, improve abit.. change the whole thing, improve alot lor...

recommended piping size 1.7" diameter...

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

muffler wont last forever and cannot be serviced...

but motorbike muffler can be serviced...

read back almost 10pages,
found out many victims from WH shop..

i wonder is the Product problem or workmanship problem?

I would say product problem mostly but the seller and workers are also dishonest. They are selling cheap muffler at premium prices and it doesn't even last for few months. I had a drop in my top speed - imagine a 2.4 litre car doing 170km/h MAX!

that's why , dun save a few bucks but end up changing again and again

i did get a quote from 'him' 6months ago,

this is what he recommended to me :
3-1 extractor
Center box (bullet shape..imported one)
rear muffler (imported also) but straight or sflow depends on your transmission and power u like.

The price with installation is around RM600 without piping yet. With piping is around RM750. Imported bullet and imported muffler. The piping and extractor is antirust /galvanized steel.

after see the price i almost faint,
because didn't expected so expensive just for a small car ...

since is a product quality + no good workmanship issues, i guess it will only spoil the shop reputation...
how come they still can survive and many outlets?

haha,
then how fast a 2400cc car suppose to run?

Let's be logical, how can it be 170km/h? If you're saying 200km/h then at least it's more acceptable and besides, it's my car. They have a few different shops with different names.

then what is the speed when using stock exhaust?

you still using it? or change to another brand? just curious only

then i guess WAI YIP also same with them lor?

No, Xin and Wai Heng are the same and Wai Yip is his brother or some sort but both of them are not in talking terms I heard. I've changed everything (all mufflers and piping) in another exhaust shop. Yes, it's suppose to be 200km/h+

thanks for the info.
would look for you again (your advise/recommendation) if i need to change my exhaust next time.

brother,
safety driving leh...

I only do that NSE once in a long long while. Normally I'll drive 140-160km/h at max

My new setup for iswara 1.3 ~
powerzone 4-2-1 , 2 inch piping, 2" mid round bullet ,1.75inch piping, tanabe straight flow jasma approve exhaust~
nw super silent... sound totally same like stock old silent iswara..

NVR do ur exhuast setup in wai heng ~!!!!!

Nice setup. Is that a new extractor or used?

robix86, mind telling where u did urs?
if its around PJ i wouldnt mind going to check it out.

while that jian hang sounds ok, im not willing to go all the way to batu caves.

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?

i'm not sure as i've not tried both... but my mechanic recommends me to use direct type instead of swirl type....

came back from jian hang ~_~

mid part mod abit, added spoon and midbox. Totaly plug and weld 3 times, let me test each time. Thing added 1 by 1.

my gen2 now more responsive d.
