Hai guys.i'm new in this lowyat forum.

Currently driving satria 1.3 carburetor.
My current exhaust setup is
1)Zenden 4-2-1 Extractor
2)2 inch nenas/flexi pipe
3)1.7 inch piping with 2 inch mid bullet
4)2 inch straight flow muffler

Previously i was using stock nenas/flexi which is the size is around 1.5 or 1.6 inch..
I've decided to change to bigger nenas because i scared of bottleneck in my exhaust system..
After changed to 2 inch nenas/flexi,low end tarak power already..
Should i stick with it,change to 1.7 inch nenas,or change back to stock nenas?

Thanks for reading yo.

dei..apa king laaaa..
actually,its just slightly low end power lost..
and the good side is,when the torque kicks in,fuh..
gear 3 macam nak terbang siot..

wei tauke 5770,come la test my car first..tak try tak tau maaa..sudah try hari hari mau maaa..

Dei..mana ada poison..i mau hilangkan u mia curious je..hehehehehe

Old satria 1.3 carburetor only..small ciku slow car..

Can..but my car slow ler..if got any TT i'll inform u.

OR,

U guys want to TT?
Basic Intake and Exhaust Modification TT.
Can hear lots of mufflers..

Hear your brop brop brop..

Suggestion only wei..hehe..if majority mau TT ok la we proceed..
For learning process also what..because exhaust system i think its quite subjective..

Hai bomoh.last time u tried my car with stock nenas.
Come try again with this 2 inch nenas pulak..

JOM! but...where u guys staying leh?

wei mau dyno ka? adoi next month la..this month koyak liao..

want to wait also caaaannnnnn...
confirm paling bising gila punya..

beli sudah..wei u still go for B20?

My low end torque is baaaaaaaccccckk!!!
I've changed back to previous nenas/flexi pipe.

To 4G13 owner,if ur car is stock,don't use 2 inches nenas or piping.suffer wei last few weeks with the 2 inches nenas..
wei low yat 82,come shah alam.i kasi test..

I'm from shah alam la dei..

To all who want to tembak me and say flexi pipe size doesn't matter,go ahead try to change to big size.
Even exhaust shop tembak me and say that flexi pipe doesn't matter.
But then after i explain my problem,then only they started to "oh ya la maybe got difference"
F**k la..off course got difference..if u compare the inner size of a small and big flexi pipe,big difference la..
Front portion of exhaust system pulak tu..haiz..
If anyone here want to tembak me,hold on..chill..
Go to exhaust shop,buy a flexi pipe that is bigger than ur current flexi pipe and install it.
Use it 1 month see u can tahan or not the almost no low end power..hahahaha

Dei what taiko..
Eh u confirm mau tukar piping ah? naissss...
Langkawi apa bikin? come la the 4G1series dinner..got lots of straight road there to test..hehehehehe

Before u tukar,come la test my car first.feel the low end power first..if nice for u,then change la 1.7 inch..

caaaannn..wei apa lu dah bikin kat kereta? LCP sudah ah?

I think because of he didn't drive car la..maybe he naik motor only..
His expression is priceless siot when i said "i bawak ini kereta tiap2 hari boss..mesti la i tau ada beza..1st day tukar sudah tau beza laaaaa.."
We all observe when driving..thats why we all finding the best setup within our budget..right?
Now i'm thinking of smaller pipe on the front portion..
Maybe the same pipe diameter with nenas till mid bullet..

What if bigger to smaller diameter?

Hmm..ok this one can link back to my flexi pipe/nenas story..
My current nenas actually 1.7 inch with 1.5 inch flange to mount the piping..
So the nenas itself from extractor welding point,goes smaller in diameter because of the 1.5 inch flange.
So that is where my exhaust system creates back pressure..
After the 1.5 inch flange,it is mounted to 1.7 inch piping,2 inches mid bullet,1.7 inch piping till rear 2 inches inlet straight flow muffler..
So..can u guys imagine my exhaust system?

Bila la mau reach 100hp..hahaha..never dyno before..
Bullet placement ah..i think the next thing to do is potong je the bullet..hahahaha

Yes agreed with u.the welding must be good also.cannot just tembak there to make it lekat..

dei how much per session ah? i tatau this dyno2 thing..

the carb tuning is using what? got CO or they just main pusing je the A/F screw?
