6G Celicas Forums

I'd like 2 see a few pics first and then depending on the final price....I could b down.

Ok guys sounds like we got a lot of interest here....enough to tell my man to start production. We will move forward once i get pics (June 30th), final pricing, and as we all know now we NEED gaskets. Thanks to everyone for your knowledge and help with answering everyone questions!

your still missing something...did you read my post about the 02 sensors ? they are different for different years. There is no way to make one header to accomidate all years.

will this header be for 94-95 guys or 96+ ?

Ok for sure, for 94 and 95 becuase I have a 95. Can someone please post up a pic of 96-99? I will be able to make them for that year too...just need to see where the o2 sensors are!
Thanks!

All you need to do is add another o2 hold and have the header come with an optional cover plate for it. That way us 94-95 guys have our singal, and those 96+ guys can have their 2.

that sounds like a good idea. but if you still need a Picture of the O2 sensors, heres one of my 96 celi.

PLEASE READ....


Ok guys, I need someones 96-99 old gt header, so I have something to go off of. Is anyone willing to give there thiers? And, I will have one ready to make so the day I recieve your header I will send you your new one out the next day. Someone preferably on the east coast so I could have it to you as soon as possible, which will be only about 3 days from the day I recieved your old header to get the new one back to you. You will also be getting a deduction on your new header!

Anyone?

should be easy to just add a 2nd tap for the 2nd senser lower to the base, dont really have to make it in the "exact location" since its gana be compleatly diff anyway I doubt it would make a big enough deal. actualy since the 2nd factory one is just mounted below the 1st cat you could go without it since its gana get the same reading as the top one and just put a Y in the wire to the first so it fakes it, (not 100% sure if you can put a Y in it and split the signal light that but its a thought.)

Can anyone second that? If the 96-99 gt's could splice the one o2 sensor into the other, I could just mass produce the one header for all gt's. Although, if this is not the case I will definatley make it possible to have 2 seperate bung holes for each o2 sensor.

I've heard of the 96+ guys doing this before. I've never done it myself, but it's very possible to do.

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.
