thats awesome, after you install them, make sure to wipe them down with denatured alcohol to remove all the oil and gunk from your hands, ect. so that they color nicely

[xs94st]

where do u get the denatured alcohol from??

all i have is vodka!

[95CelicaST]

What are you going to do about the small ~3" section that needs to be lengthened in order to fit?

[playr158]

Denatured alcohol you should be able to buy from Home Depot, Autobody shop, Paint shop.

[xs94st]

What are you going to do about the small ~3" section that needs to be lengthened in order to fit?

lotsa muffler shops around here. pretty much every corner

oh, n thanks playr!

[95CelicaST]

So you're installing it and then driving open header to an exhaust shop right after? Or a couple weeks down the road? What?

[xs94st]

i can get it fabbed today. i already hit up the shop nearby n said they'd help me out. doesnt really get busy so should be done fairly quickly

imma just hook up the header n downpipe n just hang the old precat piping on my car. its like less than a block away..if i had to, id just push it downhill

[xs94st]

okay.

the bolts goin to the cat are rusted on.

ne kinda stuff that would help remove some rust?

[tonytutino]

lol thats also another reason i let the shop do it for me :-p
easiest way i think is to just spray the hell out of them with some WD-40, let it set a few hours then have at it. that should work

[playr158]

use PB blaster is better

[xs94st]

aiite..i douched it in wd40..gonna let it sit for a while..gonna make dinner or somethin..if that dont work, i'll try n go get that PB blaster stuff..i shoulda pickd that up, i used it b4..

[Bitter]

**** that, just grind the heads off and punch them out. they're not coming off without breaking, trust me!


you'll love the topend boost you get from the header, 2nd and 3rd gear are much more fun with it than before.

[shadycrew31]

umm 2nd PB Blaster.. if worse comes to worse grind off the bolts like he said. you may also want to consider replacing your gasgets, and definatly replace your exhaust manifold gasket.

[xs94st]

yea..since i dont have a die grinder, imma go drive to my friends place tomorrow n use it to cut them suckas off..

however, when i look closely at the cat/precat flanges, the entire thing looks rusted over. i might just cut the whole flange off n just get another pipe piece to stick in

thanks for the help guys!

no pics today cuz im pissd at myself for not checkn all dis first :|

mines been wrapped for over a year without problems, and ive driven it long and hard during the year. 3500 rpm for 2 hours on the highway, 2nd gear romps around twisties, commuting, heavy traffic, etc. not a single problem with it.

yes, use new gaskets for the exhaust. get a new gasket for the cat flange as well if they do a flange for the other end of the header. they may just weld it right to the cat! honestly, dont dick around with anything other than grinding the heads of the bolts off. if theyre that rusty they're not going to be in any shape to be reused.

[Harold_Fastwaker]

where you get the header from?

I asked around on Ebay and all the sellers tell me its a direct bolt on, and that no 3 inch pipe is needed...I bought my header the other day for 65 shipped just waiting for it to come....should i wrap it? i hear wrapping causes cracks, how else can you dissapate the heat...and not bake the hood (i have a CF hood...)

As far as wrapping goes. Most of the bad cases come from people using SS Autochrome and the other Chinese knock offs.

[xs94st]

got em on today.

will post pics luego..tired.

my CEL didnt even come on when i test drove without both o2 sensors..wtf..

neways, im glad there will be no CEL even with one o2 sensor in.

[playr158]

actually it doesn't come from cheap parts (although that is a factor)

wrap keeps moisture in and causes premature rusting.

[Batman722]

got em on today.

will post pics luego..tired.

my CEL didnt even come on when i test drove without both o2 sensors..wtf..

neways, im glad there will be no CEL even with one o2 sensor in.

the 02 code is a 2 detection trip. It means that if it has bad readings 2x in a row in between warm up and cool down cycles then it will trip. Then it shuts it off and stores the code. Don't worry, the CEL will come on without an 02 in there.

[mobsterk]

i got those headers from ebay... but they didnt aling to the block.. is that the way all headers are for celicas?? do i have to do some kind of custom work on them!?!?

[xs94st]

here we go..

before:


after:




the soundclip of my muffler needs to be updated..cuz rite now its effin loud..considerin i have no resonator either.

i dug around furiously n got the silencer installd..cept now it sounds like a bumblebee cuz of increased exhaustflow without the silencer, it sounds beast

[xs94st]

yea, i know everythin is pretty dirty..it will be cleand soon

just need a couple hours to make everythin perfect inside n out

[frosty]

use PB blaster is better

YEAH FOR PB!!!!!

Nice headers, I didn't read where you said how much you paid for them, how much?


As for wrapping, I was under an impresion that said to change out the wraps everynow and then.

I;m guessing it won't but will the heatshield go back on with those headers?

[LewFX]

nice, bump up another 5hp!! total is 110 now?...your left spark plug wire looks loose

[xs94st]

yESS 110 HP OF FURY!!!!!!

lol, yea that wire is just funky, its not loose its just that square boot right there needs to be pushd on

got the headers for $51+shipping on ebay.

im gonna wrap em later, the heat shield wont attach to it.

any1 know of a good muffler that isnt very loud at all? i'll post a new vid of my car soon so yall can hear it

[playr158]

very nice!

what you need to do is find a resonator to put into your exhaust system, i remember not having one it was horribly loud.

muffler won't make too much difference on overall Db level.

[xs94st]

alritey, im sure that will make a big difference. any1 know where i can geta resonator can from? maybe the junkyard today after work..

[95CelicaST]

Any exhaust shop can hook you up with a resonator.

As for muffler.. go with a GReddy SP2 style. Looks good, not all flashy, and won't attract much attention.

[mobsterk]

those headers look just like mine, lol i guess imma have to drill them!! i talk to the guy that sale them to me on ebay.. and he said i can return them but im pretty sure is goin to be the same problem if i buy aother set of headers

[Komail]

[xs94st]

its gonna be short. u have to bore out the holes in the header to make em fit as well.

[mobsterk]

hey those are the same headers i bought!! GOOD luck buddy!! lol
yeah u have to bore them out!!

oh yeah!! what u might want to do, when u head to the muffler shop..tell the dudes to cut the pice of pipe where the 2nd o2 sensor is.. so they can weld it to the new pipe..

[Bitter]

same as what i got as well, but you got an extra gasket that i didnt! mine just came with the head and section gaskets, not the 3rd one for the cat flange. lucky ****er.

[mobsterk]

i got the same gaskets and everything!

[Komail]

Yea, um also I have a 1997 ST, I think my upper o2 sensor thingy is diffrent too....i talked to an exhaust guy, he said he can weld an o2 sensor bung into the upper o2 sensor place...gonna cost like 80 dollars

[xs94st]

it looks fine in the picture..all u do is use a 12mm deep socket rachet n loosen up the o2 sensor on your existing headers n then use the same nuts for fitting it to the new header. the only things you would have to weld are the extra piping to the cat n the 2nd o2 sensor bung.

is it the second o2 sensor (on the downpipe) that you are talking about?

[xs94st]

http://youtube.com/watch?v=0WQkjy86Ruk

theres a vid clip of my exhaust with the headers installed

i revvd to 4500rpm

[Komail]

Like my upper o2 sensor is diffrent, i have a 97, I think that 94-95 had 2 nuts, and 96-97 had just a screw in o2 sensor...

I already know about the lower o2 sensor...

[punkuup5150]

is the increase in power and soudn worth the trouble of doing this? i mean my cast iron exahust manifold is cracked im guessing from server hea to cold which i dont understand sincei live in the valley here in cali i bought the celli that way but im not sure if its worth all the work to do this so i can have a set of headers on my 97 st a lil xtra power would be awsome but the hassel im not sure if its worth it and this is coming from the guy whos goign to be doing all his own bodywork and paint the car once i get the paint in stupid special colors take forever to have come in. esp if your getting a backdoor hook up outta a paint store hehehe. but still what should i look forward to paying for a fully finished header for the celi after all the xtra o2 ports r put on and the pipeing and such is done? just a rough estimate woudl be awsome thx

[Bitter]

sounds much like mine, click my sig to hear it. i JUST have the stock cat, resonator, and stock pipe to the back.

[CAMAricer]

Hey guys. I also got myself one of those Ebay headers. But I got one for my 97 ST. So I see that these headers are about 3 inches too short...

Anyways, so I was looking around for a resonator pipe on Ebay (to deal with the noise afterwards) and saw two different listings...one for a 94-95 ST and one for a 96-97 ST (price was different too, by like $20, same seller).
So now I'm thinking if there's a difference between these years (in terms of their exhaust system).

So here's the question. Are there differences between the exhaust systems of the 94-95 and the 96-97? Because that seems to be the case.

I haven't actually taken out my exhaust header yet to see if my Ebay one fits, but in the mean time if any of you guys know the answer to this, it'll save some of us with 96-97s some hassle and time.

[Bitter]

type of O2 sensor hookup, earlier models have a flange, latter are screw in.

[Komail]

I have the 97 ST, can i change the 02 sensor hookup from a screw to the flange? what do I need and where do I get it?

[mobsterk]

u can change it, as long as the muffler shop is willin to do some adaptations to the pipes etc

[Komail]

No, I mean convert the upper o2 sensor from a screw to flange....how would you do that...

[Bitter]

why not just return it and buy the right one?

[Komail]

why not just return it and buy the right one?

I got the header from ebay for 65 shipped...if I return it and buy the right one, thats like going to be more money and time LOL better to convert lol..

[xs94st]

ey komail u want it to be a screw in not a flange? u can have a muffler shop weld on a a flat piece over the existing flange on the downpipe n then get a hexnut the appropriate size, drill a hole in the flat piece, then weld that hexnut ontop. then, just screw in the o2 sensor.


also, is to every1 in general, is it bad that my CEL has not yet gone on despite the fact i dont have a 2nd o2 sensor in at all? i just unplugged it from the harness..

[Komail]

I think its called an O2 bung, i can have that welded in to make it work out...

[Komail]

What were you guys saying when you have to BORE out holes in the header to make it fit? I was kinda confused on that part...thanks for the feedback, I have pics to take...lol

yea, when i tried to put my header on (directly onto the head bolts) it would not line up all the way. i had to bore it out a lil bit in each one so that the bolts would all get through. it was still a snug fit, i just used the nuts for the header to tighten it onto the head.

My second minor issue is that I have a slight rub/vibration from the midpipe touching the crossmember part of the frame, I think I will bend something and make it fit a little later.

theres the original support that held the downpipe in place (made of rubber, held in a couple of bolts) just get rid of the rubber and weld a small bar there (on the metal part of the rubber support) and onto the downpipe. should be snug.

Since I have a screw in type and the header is for a flange type. How can I make this work? my friend suggested to cover the flange hole and drill a new hole with a o2 sensor bung. Where can you buy a cover for the flange?

just have the muffler shop (or whatever shop) find a scrap piece from somewhere that is rather thick and able to weld on. have them weld it into place n then drill the hole so that u can place the o2 sensor inside.

[FortuneCookie]

About the 2 types of O2 sensors. I'm pretty sure that you can buy an open flange type sensor from autozone that should plug and play into your header flange.

[LewFX]

i remember using copper hi temp sillicone in between the header and downpipe to seal it better than that gasket

[Bitter]

the gasket that came with mine was just fine and i've had it apart and back together a couple times. just have to snug it down good so it seals well.


my leaky issue is the flex section, its raspy as hell

[xs94st]

okay.

since installing the header, i've been hearing this sorta ringing sound.

at first, i thought it must be some loose nuts/bolts in the downpipe.

tightened them, started driving n the sound is mainly when im accelerating from 20-40mph.

i then thought it was hitting my crossmember (maybe crappy install by myself or the muffler shop didnt weld the downpipe support well enough)

took it back to the shop and there is a decent amount of clearance between the downpipe n crossmember. (around a centimeter) and unless my motor mounts are complete crap, it shouldnt be hitting there.

then i thought about the rusty bolts that i loosened on the cat. i tightened em n added some hi temp adhesive to 'em.

when gettin out from under the car, i saw the DP support that is welded on the new DP. it is fairly long, about 1-2 inches and an inch and a half wide with 2 holes in it. i was wondering, would that be causing the ringing? considering that there is alot of force on the DP there, would it vibrate that piece enough to create resonance?

im gonna remove it but i duno when because its a tite fit and i dont have any portable cutting tools besides a craphacksaw.

any suggestions, ideas?

thanks guys!

-xavier

[mobsterk]

if u take it to a muffler shop to installed everything u lookin around 250-300 dllrs...

[xs94st]

o, i already have it all installed..

just asking about the problems as in the ringing noise that is coming from the piping.

possibly the flex pipe cuz bitter said it was raspy, perhaps mine is defective..i saw some metallic strands sticking out sooooo..i duno.

it is an ebay header.

ic komail, at least its not just me.

im going to see what i can do bout this.

i duno if my main header gasket is leaking or not, i'm gonna have to run some seafoam or somethin thru..if it is, imma just get a new gasket at toyota along with the clear tundra courtesy lights for meh doors

so the where do u suspect the hissing is coming from? the flex pipe or perhaps just the header gasket?

[Komail]

for the hissing, start your car up, and put it about 2 feet up on a hoist....then kinda feel around for any leaks, also check for black stains on the gaskets....i had some staining on my main header gasket...other than that everything else is good, slight power increases from 2-3 shift as well....same gas mpg...

[Bitter]

disable fuel and spark (pull pcm fuse), plug the exhaust with rags, crank the engine over a couple times while someone sprays with soapy water on all joints and welds.

[celicadude04]

So do you need to have the 2nd o2 sensor installed or just leave it off?

[Bitter]

your engine light will probably come on with it uninstaled...may come on with it installed as well. if the header is replacing the precat then yea you'll have a ligth on and need to use a fouler to trick the light off.

[celicadude04]

My exhaust goes Header to Straight-Pipe to Resonator to Muffler(no catalytic converters). My car is 94 st OBD-1. So my question is: should I have the exhuast shop weld a bung in my header for the second o2 sensor or leave it off and get a fouler?

[Bitter]

what happened to the cat?
