[Boyboy]

[Qr25vet]

stock muffler not so bad but with straight thru rear muffler....damn loud....I got no choice cos my rear muffler semi flow one....so since the center muffler bracket broken liao thought heck might as well remove the center muffler altogether....

hi qr25vet!

 

wat u hv said izzit the downpipe middle section which hv a muffler box?

if u remove it and become straight thru would there be any improvement on performance?

[Boyboy]

[Qr25vet]

imoprove maybe if u're using a stock muffler which is not operated...if u're using an Auto...forget it

Removing or adding mufflers wont do much but change the way your exhaust sounds. If you are worried about the restrictive nature of the stock exhaust system, remove the catalytic converter. The catalytic converter, or CAT for short, is a stubby looking canister located after your header for N/A cars or DP for turbo cars and usually has an O2 bung on it. The CAT itself is the single most restrictice part of any exhaust system. Removing it will greatly improve flow, but contribute to green house gases.

 

N/A vehicles respond very mildly to bolt-on modifications.

hi guys!

 

i would like to noe the difference between exhuast manifold 4-2-1 and 4-1?

 

could someone enlighten mi wat is their difference? thnks!

[BlueSi]

4-2-1 or 4-1 are exhaust manifold, or header configuration for a inline 4 cylinder N/A motor. 4-2-1 simply means 4 pipe exiting your motor merges into 2 pipes and then into 1, while 4-1 means 4 pipes merges into 1.

 

Some ppl claim to have better torque output with the 4-2-1 configuration while others claim to get better top end power with the 4-1 pieces.

 

You probably wont be able to tell the difference if your motor is not upgraded and tuned inside out.
