mine i changed to those like tornado ones... haha... they claim besides save fuel, also increase some hp...
my setup: capalang 4-2-1 extractor, tornado type bullet, 1.7" piping, capalang tabung at the back... my car FC damn bad compare to ori iswara setup... kinda regret but no money to mod back the ori one... haha...

how about i use back the ori wise cat con
n put the bullet to the center box place
then setting like this:
4-2-1 -> cat con -> bullet -> 1.7'piping -> ori wise muffer
is this setting help to my problem faced ?
because i can c the rpm drop very fast when change gear
or i need to change muffer to S-flow type (putra twin pipe)
any sifu advice ??

it is very depend on the brand of the muffler
but by the way u using straight piping???
if straight piping only for pick up
and the exhaust air inside the piping does not have enough pressure coz the piping is straight
therefore ur rpm drop fast compare to ori

pls correct me if i wrong

 

[ec1521]

thanks every1
my problem solved with remove the U pipe before the air filter
now the air filter box is still there but without the U pipe
actually is like open pot already (DIY)
very nice
n can feel big different in pick up
but the top speed n FC i haven't tested yet

i'm just a newbie here...
the reason why i wanna change to putra's muffer is because i don like those with noisy sound..... and i like the look of the putra or perdana's muffer....

If 4 auto one you have to put 4 x 1 extractor, not 4 x 2 x 1. The setting 4 auto car is different than the manual one lol
