questions about exhaust system

[weikhee86]

I just installed a centre bullet for my exhaust system. The guy at the shop said in order to extract n feel more power I need to change my stock muffler too. Is this true? Btw, if I want to modify my air intake system to open port type the guy said it is gonna cost around rm400. Is this a reasonable price?

 

[chocklee]

yeah...it's true. u might wan2 consider changing the extractor to a 4-2-1 or 4-1 also. open pot filter will cost about that amount. try KnN filter...most ppl ar using that

 

[weikhee86]

thanks for the info... which type is better? i'm driving a car with small displacement... would it affect high end torque if i change to 4-1? cos stock cars mostly uses 4-2-1 rite?

me use 4-1 but i really wished i bought 4-2-1 last time...

me use 4-1 but i really wished i bought 4-2-1 last time...

do u regretted using 4-1?? im using 4-1 rite from what i can see... if u rev your rpm.. past 4k... the power is sweet man... :) but the low end suffer a lil bit and the fuel consumption can be quite high sumtimes if u whack your here and there often

 

[weikhee86]

oic.. how's ur ride rollakid? wat is ur next project?

 

[weikhee86]

potssum,

how bad is the FC if u rev it often? tot might give 4-1 a try..

 

[potssum]

erm last time stock standard my gti can reach to 500km now after using 4-1,r3 stage2 cam,hotbits exhaust the most i can get is around 470km.... but again im satisfied with the power that i gain... in future maybe i want to try 4-2-1 they say this setup is for pickup while 4-1 is top end...

imo, if u have to rev quite high with the open pod to feel the power. at low revs, at best it performs like stock only or probably worse.

 

[weikhee86]

potssum,

in ur case it's not bad ler.. i'm driving a tiara btw. very little ppl wanna tweak tiara oso.. darn. seems like i'm da guinea pig here

markii,

i'll keep that in mind. thanks for the info. but if i didn't do the open port air intake and just do the exhaust i'll gain some power too rite?

 

[markii]

of course...maybe u can try drop-in instead of open pod. but kuching air filters i dont know why so expensive even for chapalang. last time i saw sty selling apexi open pod for 300...just the head. and then still need to buy adapter and pipe. try 4-2-1 and s flow muffler

 

[huakenny]

since u r using tiara...i guess its hard for u to get aftermarket extractor...

maybe piping + rear sports muffler is good enuf with a better flow air filter system.

u may get urself an used open port filter. 3inch knn will be great . adaptor u can customize it



:shocked:

weber and good fuel consumption just don't get well together.. sorry..

40% of the time i'm stuck in traffic jam
30% of the time traffic's moving, but just at a slow steady legal speed
20% of the time i have passenger in my car, mostly my parents or my grandpa, can't rev high.
5% of the time petrol is low and i haven't get any salary (if i got work) or just basically low on money
and only 5% of the time when i can really use the power and rev all the way.

no thanks.. i wished i'd got myself a 4-2-1

oic.. how's ur ride rollakid? wat is ur next project?

since you last heard from me:
-stripped interior and seats
-installed complete AE86 front strut with brakes
-changed steering arm to ae86's one too..
-installed adjustable trd shocks
