I would think the purpose of the 2nd O2 sensor is to read a change in exhaust gases, being that the OBDII is more strict on emissions, etc... otherwise it may throw a check engine light....

I would be interested in this header if you made it work for the 96+... it would be interesting to make it with a highflow catalytic in place of the stock odd shaped primary catalytic...

Either way, please keep us posted if you can make them work on the 96+...

Just my .02 cents...

Ok GUYS...UPDATE...

I went today and saw the completed header. Again, I will post pictures this coming Friday of it installed (from the top and of the undercarriage). This is how it is going to work...There will be a bung hole for the top o2 sensor...the second sensor for what I believe is the catalytic converter will be non existent. This is the easiest and most feasible way to go about it. I have talked to two other mechanics (a diagnostic service center and a header fabrication center). They both said that splicing the second cat sensor off the stock header into the cat a little below that one will not be a problem or throw an engine light at all. Again, I will make 100% sure that it won’t throw an engine light before I sell them to you because I will soon have it installed. How this will be done is obviously splicing the wire right above the 2nd sensor and run an extended wire to the 3rd sensor. Basically this will be tricking your motor to sense the same reading as your 3rd sensor.

The header will be heat coated with the color of your choice. Also, all gaskets will be included. Although, if you want the header to be ceramic coated that WILL be an additional cost. The heat coating may over a long period of time begin to flake (i'm just basically not guaranteeing that it will hold up for the life of the car, just so I don't have any unsatisfied customers). The only 100% sure way that you will be able to have no flaking for the life of the car is by ceramic coating, which again will cost a little extra (price specified in first post).

The best route that I think you should take is heat wrapping your header instead of ceramic coating unless you want your header a certain color. I personally am going to get mine heat coated (which they all come with the base price) plus with header wrap. From the bottom of the header I will be replacing the stock downpipe/flexpipe with an aftermarket piping equivalent to my 2.5 inch exhaust, and also be using a magnaflow catalytic converter to replace the cat where my 2nd and 3rd sensor will be now. This can be sold as a complete kit...Header, Downpipe, Flexpipe into a Magnaflow cat, which will then lead into a catback exhaust. THis will obviuolsy be a little more expensive due to the price of the piping from the header to the cat and the price of the cat. Or you can not take the cat and have one of your choice. This header will have a few different options to what can be added, upon your request.

All of these prices will be determined this Friday, but will be pretty close to the estimate I gave you from the beginning (in the first post).

The header will be a 4-1 design. The 4-2-1 was too difficult to complete. With our cars the difference between the 4-1 and 4-2-1 will not be significant, now in a v6 car where you have header(s) there is a difference.

So, all in all the headers will be a 4-1 design, allow the first bung hole to be available, and the second one in 96-99’s will have the wires (and everything needed) to professionally connect and run the wire from the 2nd sensor to the third.
Because of this, the header will be available for the 94-99 year GT's. The 94-95 guys will have no problem; this will be a direct bolt on. For the 96-99 guys you will simply need to follow my instructions concerning the wiring, and I will be testing this to make sure you do not throw any engine codes.

The header welds will be VERY strong, I am telling you this for the people that want to run nitrous (such as myself). You WILL NOT have to re-enforce your welds or worry about it during the use of nitrous. Although, I will be checking periodically just to be as careful as possible, but again, is not needed.

I don't understand why but my car is a 95 but has 2 sensors as shown in the picture above. So, if someone could please post a picture of the 94-95 header I would appreciate it... Just to make sure that the 94-95’s only has one sensor. I always wondered about my car? It is a 95 GT with a 5sfe but has 2 sensors and has a hood that said it was from a 1.8 liter ST???
Maybe with the picture of the 94-95 stock header I will be able to better know what is going on with my 5sfe and car!!
Thanks!

I'm in. What are the color choices? If there is a silver, I want that. If no silver, I want black. I have a 94 GT, and there is only 1 O2. You may have a Cali car or something. Or maybe it's a 96 model, that was made in 95. Let me know the details on the payments. I'm close to Hershey PA as well, so if shipping is an issue, I can get it. And, if I can get one without paint for a drop in price, I'll take that, because I plan on rapping it. If you need a test fit for a 94-95 with 1 O2, I can come up there and let you use my car. I can also pay in cash if you want to test fit one on my car.

EDIT: And I can do it this weekend.
EDIT2: If you need a test fit and a referance, I could probably pull enough cash together to get the kit fitted. If price is right.

I might be interested in a few months for the complete kit - will it be still available? Until then I'll wait for the feedback of the lucky ones that will be testing this nice package...

did i miss the price?

>
Pricing in first post...

>
Yes, I plan to have them always availible...except for after the group buy please allow 1 week for header to be made.

>

Yes silver will be fine....do you want a chrome look or a regular silver look? I will also get a complete color list up tommorow (June 28th). Yes that would be great, I will test fit your car. Please pm me your telephone number! Not this coming weekend, but next will work for me. Remember though, I still have to test it out myself. But so far so good with fitment isues. We put it up to my engine today and it looked perfect. Yes one without paint will be about a 10 dollar price drop. PLEASE READ FIRST POST AGAIN...UPDATED

sounds good, I'll deff in for one. most likely a heat wraped with chrome or that gloss black, just wana see the pics when you get em up.

maybe I should of been clearer, so here it goes... only the 94 non-cali (federal emission) GTs have 1 02 sensor. All other USDM GT Celicas 94-99 have 2 02 sensors.

Now to explain the difference between the 02 sensors in the 94-95 and the 96+

the flanges of the 94-95 both (front and rear) look like this one pictured - one is in the exhaust manifold and the second is in the primary cat (not pictured)



for the 96-99 and the top (front) sensor has this (same as the 94-95 guys)



but the bottom (rear) looks like this



for example, look at this picture again from LewFX of his header for his 99 GT



^^^^ that header pictured will bolt up to any 94-99 GT but the lower 02 bung will have to be changed to the correct flange to fit the 94-95 02 sensor

I'm not trying to be a jerk, I just need to make sure you have the correct information

^^Good info Batman. I didn't know that, and I was trying to figure out what the big deal was with these things.

BTW: I am headed to Hershey, PA the weekend after this one to get this thing put on my car. I will write a review of it to let everyone know how it is. I'm going to try and get at least 3 0-60 run times in before, and 3 after to make sure I have a reasonable accurate measurement. pimped6gen and I are trying to work out a thing with a dyno, mostly pimped6gen. I think that would better show the results for this. Let me know if you have any suggestions, guys.

>
cool beans.
my tips:
make sure its a dynojet, and bring a 3.5" floppy so that they can D/L the runfiles to disk for you.

The header install went well. Car definitely seems faster and allows the engine to breathe much easier. Exhaust is noticably louder. Sorry for the delay but pics will be up tomorrow along with a more detailed write up. Thanks.

sounds cool, keep us posted. and I look forward to seeing the pics.

you said the sound is louder, is it a good deep noise or a raspy rice kinda sound?

I do have pics but they are only of the undercarriage wiring from the bottom o2 sensor to the o2 sensor before the cat back exhaust. I did not take any pics of the header yet because the shop took it out for a few test runs and by the time I saw it they only had enough time to have the black finish (paint) on the header which was flaking off. It was not the prettiest thing, but for you guys who want to save a buck, that’s the way to go. I will be putting on my header wrap either this Sunday or Monday and will be posting ALL of the pics then. I also have another appointment with the exhaust shop this Monday (July 3rd) to install my headers back to my cat (they ran out of time while putting in my header in, so they were not able to wrap my header or do my headers back exhaust yet). I will be posting pictures and vids of the exhaust sound once it’s completed. As of now I would rather not comment on the exhaust sound because I have no restrictions, but I will...
It is headers straight back, all my cats are gutted and no resonators. It obviously doesn’t sound like the nice deep tone that I used to have with just my cat back. Although, now it’s more of a raspy LOUD sounding exhaust. I will be letting you know though how it sounds with my header back to my new magnaflow cat. The exhaust shop told me that once I put the cat on the noise should go back to the stock sounding, nice deep tone but a little louder, with no raspyness.

All in all this did not take them much time for them to do (about one hour to an hour and a half). They had to take the bottom o2 sensor, splice the wire and run the wire to my o2 sensor on the cat right before my cat back exhaust. Secondly, they needed to make the 1st o2 sensor about 1 and half inches longer as well. This again was easy, just splice the o2 wire and make it a little longer, plug it into the adapter and we were set. EDIT---I forgot to mention...header lines up perfectly with stock downpipe...only requires welding (obviously).

I have thrown no engine codes and car seems to be breathing SOOO much better. I also got my dual friction clutch and fidanza flywheel in at the same time, so to me driving off the lot I felt like I had a new car! Revs seem sooo much quicker and it feels like the car wants to be boosted. It feels as if my motor doesn’t have enough power...almost feels like its asking for more, I even chirped 2nd today by mistake! lol. Now I understand why Pressure says that our cars love boost. Top end also feels much smoother; it doesn’t feel like the car is fighting you to get there. It feels like it wants to be there. I say this mod was something that I should have done a long time ago. I will be looking forward to Bigmeanbulldog55 coming up and getting one on and doing a write up about it.

The next update will be this Monday (PROMISE)!! I will 100% be including pictures, and video if someone can help me how to do it. (I don’t know how to get vids up on the site?). I will be looking forward to this Monday, and sorry for the delay everybody, but I promise it will be well worth the wait!

Edit---read last sentence of 3rd paragraph if you did not already...

its loud in the beginning and it settles in, its quick and fast too, but again it settles in...can anyone else confirm about wrapping the header...only one website says its bad but they are selling a product.

>


I'm wrappin mine...I've only heared good things about it. I dont realy care what one individual says about them being bad...

i just took mine off, i didnt like the quality of the wrap...next time will get dei wrap not generic...finally put the dp gasket on and shortened the fouler plug by one.

I have dei wrap....would you recomend to put it on? Or just get it ceramic coated?

depends how you want your header to look like, like a header or like a mummy!

I wraped the header....loved how it turned out...I like the look of it! Seemed to make the car a little less raspy? I wonder why?
Will be postin pics and vids tommorow once hi flow magnaflow cat and full exhaust is on!!!

like it said, it gets excited then goes back to a normal feel

Ok guys, got everything on.
Car feels great, runs sooo smooth and feels a lot snappier. Horespower throughout the whole powerband has increased, and I feel a slight tourque increase.
Sounds mean now. With a slight rasp, but sounds good.
I would love to video record myself through third gear but I have to brake in my clutch another 300 miles

Well here are the pictures....
I'll have videos and final pricing up tonight...

Pic of the header...


Pic of where the header meets the downpipe/flexpipe


Another pic of where the header meets the downpipe/flexpipe


Pic of Flexpipe



Pics of Undercarriage:


You can see where the wiring is..(to the right of the exhuast) and goes up to the where the second o2 came out of the stock header

pimped, that looks awesome

Hm. I sorta want one. BUt if I swap then i dont need a header...sigh...decision

ok my guy told me that the final pricing would be...
1-9 people -215 shipped
10-20 people -205 shipped.
Its up to all of you what price we get. If people want to start leaving there names feel free.
I am working to get vids up right now.

LewFX has video up for all of you...
I have 4-1 headers back with 2.25 exhuast with over the axle exhaust, a hks muffler, magnalfow catalytic converter, cold air intake, and fidanza flywheel. NO resinators installed. When one is installed those poeple who want the nice low tone with no rasp will be able to have what they want.
...enjoy...

Also,
Bigmeanbulldog55 will be getting his header on this Friday (July 7th) and will be leaving his feedback to all you who have doubts.

Looks great
Might be a stupid question,
but this will work with RHD cars right?

And what about shipping to Sydney?

I definately want one in a couple weeks

goo...is that just your muffler making that sound or will the header actually make it sound like a Honda?

i think its the muffler with no resonator doing that
