buying muffler / extractor

[EVO3gsr]

Can I trade in my old extractor? So changing muffler is for the sound only? No other effect is it? If I change my extractor do I need to change the center bullet also?

old extractor send to junkyard....

changing muffler for better air flow...differ muffler gv u differ sound

changing extractor itself sun need change bullet

what will happen?

What will happen if u put in 4-2-1 extractor, 1.75-2.0 inches pipe with muffler and resonator into a 'not modded at all engine' ? will it give bad or good?

hmm,

1> 4-2-1 extractor will help u. im using wei yip cap ayam $70 for my 4g13 did improve a little...

2>1.75" -2" piping depend on wat engine u using. 1.3-1.5cc dun go above 2". 1.75" will be good enuff for everyday driving below 4krpm most the time....2" if u wanna 'drag' sometimes

hmm, yeah, actually got calculations wanso see what pipe suitable for you, like myself, im using a 1.3 16V engine, setup of the piping i use trial and error wan

from engine => extractor 4-2-1 => 1.7" piping => midbox(straight flow) => mid box(straight flow) => 2.0" piping => muffler tip :D => out to atmosphere arleady...

sound okie larr....power, got larr, butthen car still slow bai... :( but not recommended if using auto larr...auto recommended using 1.8" piping for a 1.6 car, even with straight flow, still can have abit power :D go 2.0 inch only if you have manual :D

for 1.5, think best is 1.7/1.8 also kwaa, not much diff, butthen dun go 2.0 all the way, sure die wan.... :D

hope i never make you go koo koo, rreading my post..ahaha,i also dunno wether you guys can understand what i said also anot :P ekkekeke

and erm, if you want muffler, go for s-flow for more silent setup :D straight flow are alwiz noisy, normally larrr :D

If after changing the extractor , muffler and piping ... But sparkplugs , air filter are stock ones... Will it affect the overall ? like, make it not so good or something..

i changed my car extractor, muffler and S-flow... running on stock filter and normal plugs... can say got some difference lar... rpm climbs more smoothly... doesnt have those lagging or lost of power feel...

 

[gavan]

nope, its perfecetly okie :D cause as long as your air-filter is not dirty or doesnt ristrict that much of air-flow, should be a problem :D plugs as long as it fires properly, its not a problem either :D

So, What exzos system should match with "Iswara Aeroback"? All is stock spec.

for muffler...try to search at 'engine n performance' forum if u r lazy to visit chop shops....

for extractor....u may get Powerzone one....got i cant think other brand..ahaha

anyway....ekzos system gotta match wit ur car performance....it is beter for u to list out wat ur car model,engine cc, n wat mods hv been done.....

 

[SkYwAlKeR]

i think a 4-2-1 extractor... S-piping which is not over 2" in diameter... bigger muffler... coz i heard from my foreman, he said small small muffler usually used in modded kancil isnt suitable... plus, it increases FC, as he claims la..
