Bang Sound When Shifting?

[amirrzz]

hello guys..i was driving my 2007 yaris 1.3 last night (kinda slow) when this crazy 2003/2004 yaris overtake me with a bang sound (it sounds more like 'BAK') +flame coming out from his exhaust when he shifted...i love the sound, i love to see the flame and i am pretty sure that that car is NA.......

SO PLEASE ANY1, teach me how to produce that sound and flame...

What model Yaris was it? Where abouts were you, may have been someone on here. Haven't heard of a flame comming out of a Yaris exhaust before though, maybe they had a Flamethrower Kit, you can buy them online if you were interested in getting flames. (How safe they are, I don't know)

I stand corrected, although it seems to sort of set itself on fire rather than make a 'blowtorch' jet.

yeah but thats a !Removed! flamer kit in that video...

you could make flames with a full exhaust system and if the car was slightly overfueling but you dont really want it to over fuel. mine pops between changes and i only took the centre box out. obviously no flames....yet

May have been decatted, and it also depends on engine mods.

[amirrzz]

its not the same as in the video...it somehow created a 'pop' or 'bang' sound w minor 'ball' flame..if u get what i mean..

does that mean that i have to buy a new full stainless steel exhaust system from the manifold? whats the center box? and how do i make it overfuel?

[Jason.s]

well you can if you wanted to, it helps yeah. the centre box ie the resonator box after the cat is what i took out.

overfueling sometimes happens when it gets mapped. more fuel bigger bang and sometimes they`d increase the fueling a little too much, like more fuel going in that air. not on purpose obviously but it happens.

owh ok..tq 4d info..one last question..is there any electronic controller for increasing the fuel?

[Jason.s]

yeah theres one or two air/fuel mixers, apexi and power enterprise do them. £200+ then getting it set up

[amirrzz]

i checked on the apexi products jz now and i saw this new Apexi SAFC NEO..Can i use this product? thx

[Jason.s]

aslong as its the vvti one and not the vtec one

[Woody27]

Yes you can use the AFC neo and just dont use the VTEC functions obviously. The only vvt-i specific controller is the Camcon by Power Enterprise.

ok,i dont know whether this is good or not..but yesterday i went to the HKS, blitz, as well as C-one dealers n i asked if they have an exhaust system for my 2007 yaris..unfortunately they said 'no'...and they told me that the 'pop' sound will never come out eventho i have a full exhaust system from the manifold and overfuel it.. one of them told me that new cars nowadays are using direct injection, the compressed air will not bleed to make inefficient burning eventho we use aftermarket fuel regulator because new toyota or even hyundai engine 'have no backflow'...what is he talking about? i dont know what this mean or maybe i heard it wrongly... so please any1, is this true?

btw jason, do you think it is enough to produce the sound if i use aftermarket fuel regulator, camcon + took out the resonator box w/o changing the whole exhaust system? N is the sound coming from ur exhaust that loud? jz wana know because i dont want my car to sound like an elephant on the street..

[Jason.s]

if he means brand new then i dont know but if he means new as in since 2000 then thats crap.

to be honest i wouldnt know if it would, have no experience with different regulators or the camcon. i didnt think my exhaust will pop or burble a little by just taking out the middle box but it sure as hell does now quite a bit, even when stone cold it pops between changes quite a bit. my exhaust isnt that loud no. certainly louder compared to standard and a lot raspier but not loud.

theres the box gone and new pipe in

nasty resonator out

a little clip there but sounds different in person and now its bedded in

[yazburner]

that vidoes wicked, you cars squats as u rev it

i want one soo bad

someone give me a well paid job please?

[amirrzz]

oh man..thats one of the coolest sound ive ever heard from a yaris thats one of a kind and thats good enough for me..but ill still surely try the camcon and and fuel regulator to see and hear the difference...

thnks for the reply bro

[Jason.s]

that vidoes wicked, you cars squats as u rev it

its actually the fumes blowing the phone lol

sure you can try those bits and see what it does. expensive though just for some popping. cost me £6.89 for a 2meter bit of pipe to replace the resonator..bargain lol
