WTA - 20V Exhaust

[hitz]

Hi all sifu's, just curious did anyone tried b4 setting up the exhaust without using and mid box and muffler.. Last time i heard that Sifu Chin tried b4 on this setup... Anyone know how is the performance compare to with complete min box and muffler setup? Also what the piping diameter if not using any muffler? Hehehehe...

im using exhaust system with no bullet..particularly because my muffler is jasma, sound not loud but got increase in pickup..if throw away muffler not sure tho...

 

[7Heaven]

throw out the muffler.... direct piping ka?
sure damn loud and decrease top speed i think....

Ya... better don't drive without exhaust... tried on my 20V BT today and sounds crazy... even got flames coming out from the exhaust! btw, mine was totally no exhaust, just 4-2-1 section only.. LOL!

 

[7Heaven]

for me the best setting for bt is use 1 center bullet and with N1 rear muffler....

wat size for piping ? 2"/2.3" ? Straight flow / S-flow muffler better?

 

[20vturbo]

7heaven,hows the performance? do u mean centre bullet+n1muffler is straight pipe setting?

 

[7Heaven]

2.3 non straight pipe setting....
performance very good, u guys can try it....

if without the center bullet, i think the performance will not so good....(my opinion la) coz almost all my 20V member also use this setting.... center bullet is a must to use on 20V....

like that ah....coz now im using twin muffler and can say that the performance was not ad and almost no sound at all.......

wat kind of center bullet should be use....beside N1 muffler is there any other option of muffler can be put in BT 20V....coz N1 mahal la....

 

[7Heaven]

twin muffler good ma, silent no noise....
im using the chop shop center bullet, outside there should selling at rm30 to rm50 only... i have no idea of other muffler, coz currently useing N1 and in track will use direct twin pipe...

I OSO THINK DIS IS GOOD SETUP LER 4 20V COZ ALMOST PIPING SET DAT CAME FROM JAPAN EITHER AE101 OR AE111 R USING DIS SETUP (1 CENTER BULLET N MUFFLER-'TABUNG TYPE')..... N D DIAMETER IS AROUND 2.3"

he he like this will go 4 it !!
been using 2' piping, mid box & S-flow muffler for past 5 year lor
time to change >_<

 

[kayy]

any disadvantages if using 2" piping rather than 2.2"?plus mated with jasma 4-2-1 xtractor, i midbox and sflow rear muffler..all in BT eng really appreciate any feedback

 

[7Heaven]

yea im mated with the jasma banana 4-2-1 extractor also, result very good with the 2.3inch, if use 2inch piping sure not so good as 2.3inch....

too small or too large also no good then 2.3inch lo...
last time using supercharged engine with 2.5inch piping also the result no so good, after changed to 2.3inch the feel is much more better then b4....
so as my opinion 2.3inch is a good setup for our NA engine....

 

[pcmoddingmy]

Bro 7Heaven, 2.3" better FC or 2" better?

 

[jabba20v]

i'm usin 20v svt a/t, removed the cat converter, the flexi... jus runnin standard
extractor wit standard piping and 2.5" N1 muffler.. kow on pick up and also
180km/h no problem but damn blady loud.....

 

[7Heaven]

Bro 7Heaven, 2.3" better FC or 2" better?

may be smaller pipe can save more fuel, but not comfirm la, coz never try 2" b4....

 

[hahaboy]

how about BT 20v with FR setup ? 2.3" seems like a bit large. according to sifu chin, 1.5" for primary 1.5m long, the 2-1 1.5" again... till the last 1 onli 2".
how abt this setup ? i ask exhaust shop make this, but he dunwan make for me, he said no power........

 

[7Heaven]

this setup might be ok for FR but FF i dunno la,
urs also FR? y dun u try also bro hehe...
ask them just do it la, tell them u pay not them pay ma kekeke....
