Bro,

For high end power, 2.2" piping - midbox(straightflow) - SFLOW muffler (what type depends on your ride).

For good low end torque, use back original piping size , 2" piping - bullet(straightflow) - StraightFlow muffler(Titanium Muffler will look good :) )

If remaining top end power but adding a bit of low end torque, 2.2" piping - bullet(straightflow) - StraightFlow muffler (preferbly N1 Style)

Bro, u mean after the 'nenas' one whole straight piping back to JASMA muffler?? If yes, is yours a turbo car with 2.5" or 3" piping? It will not too loud for turbo cars to use such setting. Biasa setup for turbo.

ok i preffer the 3rd one....for StraightFlow muffler (preferbly N1 Style) which one better between ur FGK muffler and ur Titanium muffler? seen ur FGK look smaller than titanium one, did this FGK can gv me good performance without loud sound?

Bro, FGK 2" available only for now. You should go for 2.5" mufflers.

need some opinion all sifu,

i owned myV 1.0SR.
wat da most suitable setup for me ?!

extrator + 1 bullet + original muffle ?
extrator + 2 bullet (reduce noise) + original muffle ?
extrator only ?!

i want not too loud sound and not very high fc also

hobcai: just my 2 cents...

MANUAL SETUP
1. Change extractor (without the CAT)
2. Change bullet (current one is empty, so throw !)
3. Back piping (change to 1.6", ori is 1.5")
4. Take away the S-Flow muffler (replace with not loud straight flow muffler)

Waaa.... :cry_smile: Kweng, u never told me abt dis thread...nice info bro...keep it up :_:

Been digging the Internet for a while to see whether if I can do calculation for my Kancil 850EZi EFI exhaust system size from extractor down to tthe tailpipes...

Here's what I've got so far...hope it gives u guys help

Thanks to FlameFox for dis links...some of the infos might suprise you for e.g.

1. You can make 4-1 extractor without loss in midrange torque!
2. Backpressure is not good, even ur driving an NA car wif Auto trans!

Furthermore, if you guys want to get a bit technical, u can try these calculators

1. Exhaust Header Length Computation By Bowling & Grippo
2. Calculate What Intake valve OD Would Be From RPM and CID.
3. Calculate what exhaust valve OD would be if you were maxing out the size of the Intake valve OD.

So far I've computed the followng
The gory details also can be seen at http://victorylibrary.com/mopar/header-tech-c.htm

Sorry if my post is too long...just that there too much infos on these sites that I can absorb, maybe sifus here can digest further hehehe

hallo all...

my Mivec 1.6 manual is currently using 2.3 piping..stock manifold and downpipe, changed the center bullet and using loud (but not so loud la) muffler (taken from my fren Civic) with 2.5 outlet.

thinking about the manifold and dowpipe...should i keep it stock or change it?

btw...i`m also using HKS Superflow.

Thanks all.
