i hav queries for exhaust pro answer me o comment me

i'm driving a satria neo 1.6 auto
recently i juz changed my exhaust system
4-2-1 extractor, 2 stainless steel mid box, HKS super drager 2'' inlet/4" outlet semi S-flow
piping wif 1.7"
but i stil not satisfy wif the power
the 4-2-1 is connected like "1" & "4", then "2" & "3" (if u get what i mean)

Hi bro, im not sure if my opinion is expert or not, but i'll try.

Refer to this MYVI 4-2-1 (S.Steel):

U can see that 4-1,2-3 design is most common. Manifold pipes sized 1.6". So, extractor is not really the root cause of power loss. Well, I will not say power loss the right word, as i can see that your setup is okay BUT power will be much felt at higher rpm about 5k-6krpm (FC is affected :) ). HKS SUPER DRAGER Semi S-FLOW?? Provide me a picture. Semi S-Flow like MUGEN TWIN LOOP style? If yes, then fully understand that you wanted back your pick up power. AUTO tranny has problem with keeping the right pressure.

First, Get a good S-FLOW muffler. AFAIK, 3 pipes designed inside of the SFLOW is the best to keep delta-pressure (pick up power retained). Another point i felt that needs to be improved is the center box. Is that straight flow? Any filters? U need filter to keep pressure for pick up. Piping size, if 1.7" diameter, alright for low end torque purpose..i would say JUST NICE!

Anymore hesitations, call me then.

Thanks & Best Regards,

Not S-Flow. AFAIK, HKS SUPER DRAGER isn't s-flow at all. The design goes like this becoz it is meant to create bassy sound. Besides, it is too big for your car. What is the inlet size? 2.5"? I saw the outlet of the muffler is roughly 2.5" (i dont mean the tailpipe). So, basically your car losing pressure. Time for you to get a proper s-flow model muffler bro and center box (make sure u have extra filter inside). That's my 2 cents.

Hi bro, WIRA 1.8 Auto. Let me get some info first.

Where you usually drive in? City or Highway?
Which one is your main concern... FC?POWER?SOUND?
Lastly, the way u drive the car... u like to go high revving (more than 4k-5k often?)

Sorry to ask u so many things... I just wanna know why u wanna modify exhaust before i can give my humble suggestion to u.. :)

mmmhhh...i usually drive in city n a bit of highway...
im concern bout the FC and Sound...sound like the Satria R3
i dont really like high revving...jus mainly bout 3-4k...sumtimes only about 5-6k...
so what u suggest?

 

[kweng84]

If sound and FC are ur concern, I recommend Straight flow muffler with filtered center box replacing ur center system. Another setup, straight flow center box with sport sflow (japanese route design..3 pipes). My 2 cents.
