I've never seen that before, unique. At first I thought this is what you were referring to

pointless.....

[Andy C]

not if i use a y pipe

[Casey]

kinda gay

[Andy C]

i just need to know if it works or not.

not what you think of the idea

get outa here casey! :pirate:

[S14Pow]

it works but i dont know about using it. all i think of when i see this is restriction, even with the butterfly open. I say dont get it unless u need to quiet down your exhaust extremely. and even so what happens when it gets stuck open or closed? my 2 cents

im making plenty of power.

im not worried about restriction.

i doubt it would get stuck but i was hoping for someone with experience with it.

Andy I wanted this as well for a while but I didn't find anyone who tried it yet. I have the same reasons if not more why I need this as well. I could care less if its STUPID OR NOT (CASEY) but for my own reasons I need/want.

let me know if you find out more dude!

[Neejay]

WRX's and EVO's run them. They wouldn't still be around if they sucked or failed often. I say go for it, but put it in the downpipe where it's at least 3".

Also, just don't get a cheap-ass one.

i doubt anyone on here has one or has used one, i say try it but of course don't leave it closed when doing high rpm or high boost. bmw does it, even though i think it's only on n/a applications (as far as i know) and its more for noise restriction than back pressure (even though i figure your not concerned about back pressure). go for it!

[Neejay]

Andy, QTP is a good brand.

it says dont close when you are running high boost.

Ive used one. Its just whats called a cutout, domestic guys been using them for decades.

Only real reason to use one is if your exhaust is relatively restrictive, but if you have a 3+inch free exhaust you might not see any real advantages, unless your making some good power.

i just want to know if its will quiet the exhaust without a y pipe.

i do have 3"

Oooooooooh, I looked at it closer, its not a cutout after all.

Actually, that looks pretty stupid if i am understanding correctly. It just goes in-line with the exhaust pipe, not as a secondary vent to the outside.

I would say it probably will quiet the exhaust but it might get stuck form h heat or carbon buildup and it is def some sort of restriction.

I dont like it.

[Andy C]

i respect your opinion.

i think i'll take your advice.

maybe i'll just throw a silencer in while i'm daily driving it.

[Slip N Slide S14]

maybe i'll just throw a silencer in while i'm daily driving it.

If all you want is sound deadening, a silencer is cheaper, and pretty reliable, thats the way to go.

[Andy C]

but i cant just open it up when i want to

thats the only thing

you know, when that mustang pulls up to you hehe

maybe its a good thing considering thats y i dont have a license anymore lol

[Slip N Slide S14]

I would almost say that with that valve in place, especially with a tuned car, it might run like crap.

[Andy C]

yeah i'll just keep my 3" and put some of that sound deadening tape around the back of the car.

i have a daily driver anyway

[Slip N Slide S14]

OR get a quieter exhaust with an electric cutout at the downpipe.

[FlatWoodsMonster]

Look on 2:45 of this vid

[Andy C]

what exhaust would u recommend?

im making 300+ hp so i need 3"

[Infinite]

there are tons of options to quiet down your exhaust without restricting flow
some people run 2 mufflers, one as a resonator, one in the normal spot
burns makes a nice low profile straight through muffler that works and sounds great

[Andy C]

i'll check it out

thanks will

[Neejay]

Ah, I reread your first post. I'd say don't bother with it. I didn't fully read the Apexi link.

Like I said and Slip N Slide, 3" downpipe + electric cutout + quieter exhaust.

[Infinite]

i'll check it out

thanks will
yup
i can help with finding and fabbing the stuff you need

the problem i've found with most cutouts is overtime the motors fail, they vbreak
butterflies vibrate loose, etc

[vqdreaming]

that twin turbo g37 in superstreet used that apex'i one, but i would just get a quiet exhaust and an electric cut out, thats what i wanna do whenever i get around to the vq swap,

[Infinite]

ok help :)
money

[Neejay]

money
hahaha

[Andy C]

how much?

[Infinite]

however much the parts cost + welding cost
duh

[Andy C]

well yeah

that was kinda my question. how much is that?

[Infinite]

well
cost of the muffler, or whatever you choose to do
cost of piping, welding time (hourly)

it all depends on what you want done

[Andy C]

i want an exhaust that can support 400hp, and is reasonably quiet, and looks good.

and sounds good.

am i asking for too much?

[Infinite]

no youre not
3 or 3.5" back
2 mufflers
you should be golden

[Andy C]

how much do ya think that'll cost me?

[Infinite]

what mufflers joo want?
i'll have to work up a price

[Andy C]

i dont know anything about mufflers.

your the pro. what do u suggest?

[Infinite]

http://burnsstainless.com/UltraliteMuffler/ultralitemuffler.html
those
if you want epic quality

[Andy C]

i forgot who i was talking to

never mind. i'll just buy one somewhere. im not spending 300$ on a muffler.

[Neejay]

hahahaha!

[Infinite]

that would be my first choice. lol
i'll look around and see what i can find :p

[Elizabeth Reed]

hm i've never heard of running two mufflers. thats interesting

[omgtofu]

if this specific one is designed not to be on a secondary pipe to dump with, and is meant to be inside the only exhaust pipe you have to restrict flow, then its pretty fucking retarded and you shouldnt do it.

[Elizabeth Reed]

hey will what about the aeroturbine mufflers? they sound good. i noticed charles on here has them on his supra

[Infinite]

they are nice pieces, huge but nice
they seem to quiet it down a bit as well

[Elizabeth Reed]

yeah im jw becasue i hate loud exhaust and im lookign for something that will keep everything quiet to a certain extent
