Hi, need advice from sifus.
Driving 1.3blm, manual.
Just change my header, 4-2-1 type, midbox and muffler still stock.
Which one is the recommended setup?
1. change midbox and muffler and add bullet.
2. replace midbox with bullet, and change muffler.

Why do i get the feeling that leaving the rear muffler stock will always give you the umphh for town use and short sprint especially for auto N/A vehicle? Correct me if I'm wrong..

becoz stock muffler is s-flow. so there are more backpressure compare to a straight flow muffler. good backpressure give you good pickup.

But its quite different from what the exhaust expert says that backpressure is no good at all..
I am getting bit confused here. Anybody can enlighten me on this ?

Thanks.

hii all.. i m newbie here...... i have question about piping for my mivec.... since my mivec is turbocharged....... i hav do the piping 2.5' direct + hks drager muffler..will it consume more fuel (because heard from fren piping effect fc), and will it be very loud like gangster or ah beng car?

Backpressure is not something you want. What you want is smaller pipes for higher velocity of the exhaust gas.

The notion of backpressure is good is wrong, as it is the gas velocity that plays a part in scavenging the exhaust gas pulses out.

Usually smaller diameter pipes will have higher velocity.

proper setup wont really affect your fuel consumption bro

No issue. If all remained stock and just change rear muffler to what you've mentioned, power wise, you get better power at higher end especially you go for full pedal, but that depends on your cat con also. If cat con clog, you get bad FC. Pick up wise, you will feel it decreases. Workmanship wise, no issue on that but i need to know the size of the muffler. Worried the body too big.

Went to one of kweng's branch at puchong last week to install my exhaust. the workmanship is excellent. highly recommended. TQ.

 

[peterj]

tq.... actually i plain to do piping 2" only.. any comment? heard from ppl turbo car cant do too small piping... air might stuck at engine and coz engine no power... 1 shitting mech told me at least 2.5"

 

[peterj]
