so how does our stock extractor fare? :rofl:

still thinking to change my muffler ornot as there is some 'tick'tick'tick' sound when shaking it (it is getting irritating:banghead:) the exhaust shop at taman sentosa near continental tyres ask me change to a stock looking but smaller box muffler for 300rm.. but my man concern is to change my extractor. :idea:

basically I wish to have a good response in throttle revving and during gear change.

How is utr shortshifter?
The stock extractor does not fare very well unfortunately. Cause its a very short extractor and leads to the cat directly. After that, the exit from the cat is very narrow (see the 90 degrees bend after the cat).

If you want to change, should change the whole set including the extractor. But I must warn you to avoid straight thru mufflers. TPs and ROV seems very active these days. Recently saw a WRX kana stopped by TP along Ang Mo Kio. Open bonnet and TP looking at the exhaust.

So, must keep it as soft and low profile as possible.

For inspections, must get workshop to do.

Power wise, as I have said, expect around 10HP. Won't fell much of a difference though.

See attached pic.. does that look press bent?
i speak with experience.. just because you dont know or havent found doesnt mean it isnt available..
custom mid section mandrel bent 2" piping for neo with 1 midbox = RM180
custom neo end section 2" piping mandrel bent = RM90
muffler - depends on what you want ranging from rm80 to rm300..
4-2-1 extractor.. imitation.. r3 or powerzone design.. rm180 if you know where to look.. cheaper if 2nd hand stuff..
i even have dyno charts for stock, full hotbits & custom setups running on my own neo..
but lets share that for another time.. :P
So are you say you can find mandrel bend custom piping for that price? Mind sharing the dyno charts?

Lol. I only like straight thru for Turbo cars. Cause it maximise power.

But I am quite keen about refdee's custom mandrel. If can custom 2.5" stainless steel will be awesome.
found a speedcircuit(or is it superstreet) replica design for neo, 4-2-1. Stainless steel type for 600rm with flexi pipe included. welding looks way better than hotbit's... thinking shld i install or to wait for turbo.. :banghead:

yes but only for satria neo's and other limited models.. the shop pre order from the factory so its mandrel bent nicely for us.. usually they make these orders for common sizes like 2".. i'm not so sure the place has ready made 2.5" custom pipings tho..

chart?

red line - full hotbits + minor mods..
blue line - full custom with piggyback.. (minor mods identical with red line run)
from my own reasoning, thats at 15hp gain which on a lightly modded neo, could never come from a piggyback alone.. so let say if i ran the hotbits full system with piggyback, i dont think i could achieve the redline figure.. so in the end, no matter how much the gain was that came from the custom system, in the end the custom system cost 50% less then the full hotbits system.. so its better hands down.. in my eyes.. :biggrin:

actually i made 3 seperate runs at 3 different time..
stock - 105hp
hotbits + minor mods(acp,lcp,TB polish,iridiums,cable plugs) - 115hp
its piggy time - 130hp :tongue:

hi,
i just got my satria neo 1.6AT (2nd hand).
then, immediately went to F1 exhaust specialist at jln genting kelang.
intent to install 4-1....but F1 guy advise me just to install their custom bullet to replace original bullet (after extractor) and to install center bullet for AT.

then I just follow his suggestion. however i still feel that the pick up is not as what i expected.

meaning they replace the catcon with a bullet??
correct me if i'm wrong but stock neo exhaust system doesnt have a bullet.. the only thing u could replace is the catcon or the midbox and for an AT, doing that doesnt do you any good.. are they really exhaust specialist?? :P

if your system is not stock then i am guessing you are on 4-2-1 with bullet and wanted to change to 4-1.. i'm confused.. :hmmmm2:

yes, my system is stock.
yes, they replace the catcon(we can see it from the bonnet top)
last owner alredey change the tabung tgh with bullet(but not suit for AT), then i'd changed it again to buulet taht suit AT.

I don't know much about crank pulleys, but what I heard is that if the tension is not properly adjusted along with snaping your timing belt, it might blow your engine causing your piston to hit your valves and bending it :smile:

You're driving neo? I suggest you get those adjustable pulleys I heard they are quite good for your campro and/or cps? :smile:
Btw I think you meant Arospeed right? You're getting the whole filter kit? I heard it's quite cheap, comes with the air ram pipe as well for around RM299?
After you install and try the open pod do share with me your experience thanks.

why? could damage the belt? or some other issues...please explain more details on it....eager to know
Stock crank pulley is carefully tuned to reduce crank distortion. aftermarket is not. you cannot just make a similar looking pulley is not
