muffler question for turbo car

[evolancer]

hello all sifus:
i just upgraded my engine to 1.8gsr....my mechanic changed the exhaust piping to 2.5'' and oval shape muffler..the muffler tip is 4-5''(not sure)!!!im happy with the car performance but the problem is i cannot tahan the noise produced..somemore i dont like the big exhaust tip...
so i changed another type of sillent muffler but the car performance was so suxx that i had to change back to the previous one due to the restricted exhaust flow...

Any muffler that is suits for turbocharged car without generate so much noise yet the car performance not much affected??
as for the muffler outlet,wat is the best diameter(prefer small one)..
thanks

yo bro
i'm driving a gsr oso n i'm using RSR oval muffler n 2.5" for piping
u can try RSR bcoz my 1 does not produce any noise n the performance is superb
the outlet diameter for the car u can use 3"

Hi, maybe u can try adding a bullet? Or maybe u can change to a bigger muffler, should be able to tone down the sound a bit.

Just my 2 cents...

yo evolancer
RSR is a brand

[sta]

when ppl say 2.5 inch or 3 inch, means the inner or outer diameter?
if i use a measuring tape to measure is it accurate ?
bcos im afraid of buying a muffler which doesnt fit my piping.

 

[gsrTurbo9166]

it is hard to measure
for eg:
japan 2.5" is measure the inner diameter
but malaysia is measure the outer diameter
it is depend on the brand of the muffler u buy n where it from

juz drop by to Jafa exhaust shop
n tell him wat u wan
be sure that it got JASMA tag to it
coz JASMA is some kind of our JPJ that has same function in japan
if the exhaust wif JASMA tag it mean that the exhaust is approve by them n pass the noise test

The loudness of the sound produced by a muffler depends on the internal design of the muffler, not the size of it. Having a larger diameter piping allows for more exhaust gases to flow faster. As such, it depends on whether your muffler can effectively "muffle" the volume of gases effectively.

Since some mufflers can't handle this volume of gases, mid-boxes are sometimes used to aid in the sound dampening process.

But take note that theoritically, this slows downs the flow of exhaust gases and increases backpressure.

Hope this helps.

mY suggestion wouLd be
1 APEXi
2 HKS super Dagger
3 RsR

tis 3 mufLers are in mY top 3 List, and im using the RsR for mY 2.0turbos..... quite nice the sound..... but in mY opinion u stiLL cant avoid the 'bising' sound......

sumtimes mY car can be heard a miLe behind Like LorrY sound, ha ha ha, that during warming up session in the morning Loorr....

peace man....

zakie:

ya i agree,the sound level still high but not as high as those ciplak muffler gua??
how about ur car performance??feel any restriction of the exhaust flow??

Bro Evo Lancer, for turbo engine of course it will make a loud noise.
but the diff just onli the level.
may u can try HKS Super Dragger. this muffler very nice sound and the sound lower than other such as N1,Hyper etc. or maybe u can try FGK(Fujitsubo Giken) oval type and u won't regret it.
i far as i know, the diameter 3" mean the size of the outside diameter.for the 3" piping maybe the inner diameter arounf 2.8".

just my opi. correct me if i'm wrong.
