free flow exhaust

[Corollaman]

Greetings tuners!

At present I have a 5A-FE in the corolla and i'm just doing some light mods to it. I freed up the intake a bit and now i'm looking at the exhaust.

What exactly is a free flow muffler? Do i have to change the whole pipe? What kinda performance gains should i expect?

What about the noise factor? Can it be relatively quiet?

And, most important, how much dineros i looking at?


Thanks,
Avin.

[roadhog]

that just mean u have no restrictions from dron't to back i just pipe
and it is very loud

it is very loud

Free flow yep..

Best you just drop 2 inch exhaust and leave the resonator and put in a barrel (not a noisy one though) 2 inch exhaust from front to back will cost about a grand or so.
Check Imraj, he can give you a good price for best quality work.

$1000 is too much............

as the man say.............check Imraj Muffler shop

[Corollaman]

^^ Where is this muffler shop located?

Also, in your opinion, do the gains justify the expenditure?

[plex]

you will gain a few hp, what you will notice is the accelaration is better.

Afaik h/i/e really helps the low end performance on toyotas

zer0xp,
En ingles por favor.

^^^ h/i/e = header/intake/exhaust

and a nice sound from the engine..

Is it true that the length of the barrel alters the frequency of the tone....while the diameter alters the noise output?

[gizmo]

was d difference between the cat back and this free flow......ent both free flow so it shudn't hav a difference rite??

imraj is located next door to southern sales car warehouse. where dey does park all the cars nah before they sell

Yup !!!!

um...SAN FERNADO WE TLAKING BOUT HERE?

yes longer the barrel lower the tone, theoretically it should be.
longer the barrel more the noise from the exhaust is exposed to the dampening.

was d difference between the cat back and this free flow......ent both free flow so it shudn't hav a difference rite??

from wat i been told from other tuners, catback is the entire aftermarket part from the downpipe to the barrel. ie downpipe, cat converter n barrel
a free flow barrel is jus that part alone

um...SAN FERNADO WE TLAKING BOUT HERE?

yeaaa cross crossing to be exact, i think

[halfbreed]

far from quiet, i put in a resonator in my once free flow system and it toned it down a bit, wasn't getting that stinky raspy sound anymore which is cool but i wanna minimise the noise coming into the car.
definitely feel the difference if yuh runnin free flow but yuh must pay a price for most any and everything.

Pallie the Southern sales warehouse he is talking about is located on Cipero Road, San Fernando. It is about 1 mile from Southern Sales by the Cross on the same road. You just head east. They do excellent work.

[Corollaman]

Cool man, I will check them out and see.

how do you all rate his work ?

[MadCrix]

9 out of 10

the reason is not 10 out of 10 is casue he not free

Downpipes only come on turbo cars, catback means: From the cat (catylytic converter) back... hence the term cat back!

Free flow means the muffler doesn't have lots of baffles and bends inside of it like stock mufflers do.

For future reference remember N/A exhaust is like this.
Header->Cat. converter-> midpipe-> axleback/tailpipe to muffler

Turbo cars:
Manifold->Turbine->Downpipe->Cat. converter-> midpipe-> axleback/tailpipe to muffler

^^^ yup Jim's got it on spot right thurr

my thing is, I kinda VERY fedup of the drone of my exhaust, I wanna put back in the silencer but knowing that I'll be adding a restriction, my idea is to upgrade the piping to about 2.5" from manifold go back, add a resonator and barrel with 2.5 inlet....u know those fancy-shmancy barrels with the silencer insert nuh

is 2.5" overdoing it?
or will 2" be sufficient to null de effects of reinstalling the silencer?

[Jimbo]

your exhaust is an entire system and it is only as efficient as its smallest point... if you still runnin the 1.5 SOHC carb and you want some kind of efficiency with minimal noise then stay at 2" and get a 2" stock muffler like from a stock SiR

[Greypatch]

top post jimbo...

we should archive sheit like dis

[bleedingfreak]

From an SiR? I cornfuzzed...

[Jimbo]

Thanks Patch, I try...

Bleedingfreak, a SiR's stock exhaust system is 2" in diameter, even the muffler is 2" so if you want a decent 2" flow with minimal or non-existant noise, then get one,
any clearer?

I thought he had a Toyota
