anyone can tell me what is the bad part if I never change my exhaust pipe that is rusted inside ? FC will increase?

adding air intake to your car,

what modifaction is needed to your engine and how much does is cost?

sooner or later ur exhaust pipe will fall off in the middle of the road....

a leaking exhaust pipe (bocor) will increase fuel consumption as well....

ur car already has an air intake....

unless u mean changing to higher flow air filter, what car/engine u driving??..

driving normal swift.

get a drop in air filter from K&N is good enough for city drive...

i just changed my exhaust.. but the sound really loud.. kind of like ah beng.

Did you go to Pakar X-os Ah Beng?

Big pipe + big* muffler = big beng.

You should opt for the ones with silencer, then won't be that loud

mine also damm loud just change middle bullet straight type and muffler straight type for my manual wira...but cruising at 130kmph the sound is so unbearable. also the fuel consumption naik also but pick up 2nd gear, 3rd gear damm good. how to solve this i prefer silence and good fuel consumption...is it the sound make me press the oil a lot and feel the power of pickup..physcology thingy sien

the other day i went to a shop cuz i am facing the same problem as blueapple. he told me to fix another thing that has s-flow or smtg like that juz before the muffler i think. i own a kancil and he said its bout RM120. does this thing really work? will the result be significant enough? what was it that he was refering to?

back to stock setup . or 1.7" pipe + s-flow muffler, as recommended for a 4g15. Not sure which engine you have. Having a straight-thru muffler definitely increases the sound level by alot.

a S-flow type muffler + center bullet should keep the noise level down, or so I'm told.. that seems to be the consensus.

i m now using a straight flow muffler and a centre bullet. now, the guy told me to add another s-flow thingy between these two. it should reduce the noise? but will it quite enuf?

yea if add 1 more s-flow will reduce the noise and don't makan petrol so much?

yea..... reduce noise...

makan petrol or not depends on ur setting....

pipe not that big la.. not like those pipe where kucing also can go in and breed.

my engine is 4g13.. also same setup as blueapple.
but if put another s-flow jsut before the muffler.. i think power sure reduce.

bro, can i ask this, normally the sound can reduce bout how many percent? roughly la...

makan petrol depends on setting?

which setting is more makan petrol and which setting will save petrol. please enlighten me

too much restriction will cause bad power and high fuel consumption... what is ur setting now??...

this i dunno how to count wor.... depends on ur s-flow inlet and outlet... pipe diameter... engine displacement... muffler... etc.....

normal one which suitable for street use...

4-2-1 extractor... original route piping... midbullet (replace ur oem midbox/catcon)... s-flow/straight flow muffler....

piping size depends on ur engine displacement and what u had modded.... what engine are u using now??

my setting now is 4 - 2 -1 extractor, mid bullet and straight flow muffler. i really like the setting now. the only thing is, scare jpj will kacau bcos of the noise. usually 1st gear when tekan only damn loud.

If u guys dont wan loud sound, dont use muffler. Use tail pipe and replace the muffler with another bullet. Sure lesser noise.

If still wan use muffler, and wan silence, then add another bullet also.. but less power la..
