I was thinking of putting in a straight flow exhaust... but then i hear a lot about back pressure importance and stuffs. please advise....

straight flo as in the box or one long straight mid section. if it's the box, keep it s-flow but with bigger internals.

straight flow as in ermm... the box where i can see tru it to the other side...

currently im on sflow and its partly see tru if angled properly (when u see it tru one hole to the other side.) Mine has a plate on the mid section. 2 inch internals. but on stock pipes.




Dotted lines is the line of sight that u can see tru it if u angle it properly. its still consider sflow?

My ride is MyVi automatic.

you can use it if you want ler, no problems 1
Just make sure got enough backpressure

why need back pressure? i read some articles in the net says that to reduce back pressure as much as possible ler... im really

s-flow muffler...

My Honda exhaust tip rustied, I changed twice but it cannot last long. The whole exhaust still okay but only the "outlet part" is rusty !! Any advise ??

A very good and easy understanding write up about exhaust system.

2nd to this. You cannot tarik long long one.. but different people have different taste.

DUmb me, but will there be any benefits changing the exhaust flow except for some noise change?

Then what do you call this type of exhaust, with a side pipe?
Whats the benefits of this type of muffer?

Can it be also classified as S-Flow muffler?

why so easy rust??... original replacement muffler arr??..
previous flood in johor, my friend's gen2 muffler rusted inside because she drove pass a floor and the water being sucked into the muffler... thats why people say driving pass a flood, gas pedal must constantly revving so that water is not sucked back into the muffler.....

changing to straight flow reduces back pressure.... good for pickup in manual cars... auto tranny cars, better stick to s-flow box...

twin loop exhaust... usually used in vtec engines....
but i dont know how it works la... so many loop will cause restriction rite??...

Heard that it works by letting the exhaust go through the muffler twice.
So the noise is filtered twice, but without actually using two mufflers and no need for restrictive silencers.

I've once used a straight flow for my previous wira (auto) and totally regretted the decision.

the oredy lousy pick-up becomes lousy-er. FC increase terribly. and worst of all, the sound is irritating.

after a few months of using it, I sold the car.

If u thinking of using a straight flow, think twice.

cheers.
