Talking about silent mufflers, IF i would to leave everything stock in front of the OEM Mufflers, then change it to a S-flow or something like an S-flow (which is quietest?), i can expect nearly no diff in sound?

What is the cost of doing the checking and can it detect a faulty MAF also or not? Do you know what is the price of a new O2 sensor, need to standby $$$.

S-flow is noisier than OEM ones for sure
But for cruising and all, close to no sound for S-flows as well, so yeah no worries ^^

what is over run??

those sound when you rev, then u let go of the gas pedal, then the braaappp sound 

it can go either way....

correct setup...gain

wrong setup... lose

well...getting the pipe size correct is one thing.. dont la go put 3" pipes on ur 1.5

alot of diff factors from pipe size... pipe bends, type of bends, muffler, centre box/bullet... amount of centre box, bullet etc could contribute to it.

best to find another car which has the same engine and find out if their exhaust setup has benefitted them

Ei friends... I am just started to use PIAA wipers by today... Any ideas can make it become safety? 

Lolx... I have posted wrong topic about the wiper here ady~ Paiseh >< Hmmm... the outlet of muffler means the hole of the muffler? But if the inlet not same size as the pipe...then how?

Can teach me how to check whether exhaust got leaking or not?

however, i have 2 questions to seek sifu wisdom:
1) after the extractor mod, need i change the rest too? (a full set up on another car yields only 2 more hp with mid -> rear pipes and mufflers changed)
2) anyhow to silent the extractor sound? wrapping or coating?

change bec wat?u means change to stock?wat the member in ZTH experience?i full throttle and the rpm will climb,but around 3sec then it will drop bec lo

familiar issue with my Civic FD1. Previous top speed 210kmj, after some other mod, mid range increase but top died at 185kmj. The air filter/air sensor is the culprit.

Just sharing, as the air/oxygen sensor is related to exhaust system.

stock materials are either cast iron (mostly) or steel. the main reason why stock extractors wont heat up the engine bay so much is coz they have heatshields on them... u will rarely see a bare stock extractor (unless pureposely removed which imho, is stupid as it works well and even looks better... stock extractors are fugly...)

aftermarket extractors wont be able to fit under those heatshields and hence are usually exposed and will dissipate the heat freely into the engine bay...so either ceramic coat (expensive) it or thermal wrap (cheap) it if ur worried.

but if u put a bare cast iron header vs steel header.. the difference in heat is negligible in regards to engine bay heat....

Oooicc... I don't know y my magma engine heatshield got link a hose to the air filter there o.O

Yup    I just get car license for two years only and I am a 17yrs old guy only... Need sifus and bros to teach me leh

bro eventhough you limit your car at 190kmh, i'm sure that you can outrun cars anytime you want to.. because of your 'siput sedut' there
as for my NA car, AT some more, i need slightly higher top end to do so, i suppose..
