Hey everyone,

The company I am Vice President of, Draxas, is considering developing a header for the new Scion tC. I know this 2.4L engine also comes in the Camry. I wanted to know if there currently are any headers on the market for the 2.4L engine in the Camry.

We currently have a header for the 2.3L Mazda6, Mazda3, and Focus, but we want to expand into new markets. We feel the Toyota 2.4L engine would benefit from one of our headers.

If anyone has any links to a header currently out for the 2.4L engine, please post them here. You can also email me at:

Nikolas@Draxas.com

We will need to have a donor car come into the shop (Glendale, CA) for R&D purposes, so if you will be buying a tC or if you are a dealer, and are interested in helping us with the development of our header/exhaust, please contact me. We are very eager to get started on this project ASAP.


Happy Motoring!

Nikolas

all the headers I've seen (which has been very few) for a 2.4L toyota engine have been custom fabricated. However it'll be great to have a company come in and snatch up some of the aftermarket support forr the TC.

I'll pretty much have to get everything I want custom fabricated or modified to fit my timetable of a full running turbo charged set up before November.

headers for the tC would be nice. thats going on my list if i decide to go N/A.

Hey Draxas_vp I sent you an email. I'm from speedrush performance in san antonio ,tx. Pls reply-thanks

san antonio a? where at?

Hey! I'm in, I send you an e-mail. (Guillermo).

trd i know has a prototype header for the tC and should be released at the same time with the s/c. it all depends if corporate gives the green light.

judging the faith of board members regarding trd products i don't know if they should come out with one. :roll: a performance header should give the tC a good bump in power cause i have feeling the stock intake/header/exhaust system is very restrictive judging by the 3hp difference between the camry and tC. hopefully someone lends you their car to r&d the header. i know that 7th gen celica owners gave up their car for a free header for a couple weeks.

well of course trd has parts for it... but another one would be great if its not over priced...

TRD is a good company. its also good to have a wide selection of parts you want/need. some companies might have more power and some might have good quality and some might have both power and quality.

GWTC,
I replied to your email.. Im sure we can work something out.


Nikolas

never said it was bad if another company made a header or any other performance parts for the tC. the more the merrier.

i see that your company currently does not currently make a product for toyota, how much r&d time do you expect to spend on this product to make it worth while?

Our header fabricator/designer has over 30 years of experience designing and fabricating exhaust manifolds. He has made headers for Porsche 944s, Ford 289's, Mazda 2.3L 4 cylinders, and 3.0L V6 engines. The make of the engines doesnt have much of a play on how the header is designed. It takes a good undesterstanding of what works well on internal combustion engines, (tube lengths and diameters, collector styles and outlet sizes, etc).

Once we get our hands on a stock exhaust manifold, we will inspect it for factory inneficiencies, and we will point these out on our website. I have a pretty good idea of what the header will look like already, its the small details that will be worked out once we begin our work.

We will of course dyno test our designs and that information will also be posted on our website.

Nikolas

I just wanted to bring this back up to the top seeing that traffic has picked up now that the Scion tC is beginning to show up at dealers.

I have already had one person contact me about helping us with product development. If you will be buying a Scion tC or you work at a dealership who wants to help us out with a test car, please contact me.

We plan to offer both a header and a higher flowing exhaust for the tC.

Draxas_VP I have one question thats been buggin me since I saw the tC. What are you going to do about that huge eye sore of a thermal reacter on the manifold? It causes the motor to run regularly and has 2 O2 sensors on it, which is also for smog. Wouldn't messin with the thermal reactor mass with the computer and cause a check engine light on? This design has been in the camery and the old celica motors. Removing the thermal reactor will cause the check engine light to come on, cause the motor to run rich and cause a rough idle. So, this is only to inquire how is a header going to be built? I have gone back and forth on this subject and still go back to "it can't be done legally." :(

Nismo makes a header which has a pre-cat built in for the Sentra SE-R / Spec V. It costs a fortune (like $800), but that's what you need to pass emissions and have a header on that car. It is possible to design one. The question is, will it be priced so that anyone will buy it.

Thermal reactor? I was under the impression that it was just a heat shield, just like on my Camry's 5S-FE engine (2.2L).

Thermal reactor? I was under the impression that it was just a heat shield, just like on my Camry's 5S-FE engine (2.2L).

I am sorry to say that under that bloated heat shield is a thermal reactor (certain type of catalytic converter for smog.) I wonder how a header will be done, and still be smog legal. :shock:

It might be that the first header we release WONT be street legal. We sell a header for the 2.3L Focus that is classified as a Race Header. The Focus has a HUGE catalytic converter built into the stock manifold as well.

We could design a higher flowing manifold for the tC that has a high flow cat built into it, but the price will go up.

We have a way around the Check Engine Light situation and can include instructions on how to prevent the CEL from coming on, even after installing a Race Header.

As soon as I have the chance to take some close looks at a tC and the stock manifold, I will be able to shed some more light on the matter.

Nikolas

very nice!! A race header and have the check engine light stay off!! Now thats R and D!!

o2 sensor "cheaters" can be used to trick the PCM and keep the CEL off.
They're generally just a resistor jumped inline with the signal wires,
and it keeps the PCM from getting the signal that would tell it to throw the light.

Hi Nikolas - I sent you an email.

I have a 2002 Toyota Solara 4-cylinder (same engine as the Scion tC - 2AZ-FE). I have been searching for headers for a long time, and I have not seen any released for this engine.

If you create headers for the 2AZ-FE, I would be interested in purchasing them - especially if they are Race Headers :D as mentioned in your post.

Thanks

I noticed you said the first header will most likely be a "Racing Header"? So does that mean that you plan on releasing a "street legal" one. Since you are based in Cali, I'm sure you're familiar with CARB.

Any chance of a CARB Legal one?

Also, I live in So. Cal. I recently sold my Corolla S and plan on getting a tC. Not sure how soon though.

That is correct, the first header will be a "race header" with no integrated cat.

Even if we build a header with a high flow cat integrated, it will take a decent amount of time and money to put the header through the CARB testing procedures. If we do create a CARB legal header for the tC engine, you can expect the cost of the header to be substantially more than a non CARB approved header. But at least you will have the peace of mind of having a street legal modification installed.

The person who bought their tC and contacted us said he should be picking up his tC this week sometime. We will more than likely dyno the car on July 17th (everyone is welcome to stop by for our $50 Dyno Day at R&D Dyno in Gardena, CA). We want to get a baseline on Horsepower and Torque before we begin development of a header for this car.

Nikolas

Did someone say race header for the tC? Hell yes, I want one!

There is alot of talk about a header for the N/A motor but what about those of us that will have the S/C installed on the cars? i know that the stock header will only cause bottle neck in the system with the stock header so a aftermarket one would great. thanks

Unless there's some kind of clearance issue (which I doubt) a header should work on the engine with or without supercharger.

RE: Supercharger

Our header will work on engines that have a Super Charger installed or not. For those people who opt for the dealer installed SC and later install our header, they will be in for one heck of a Horse Power increase.

We are wrapping up our production of headers for the Mazda6i right now. I hope to get the donor tC into our shop for prototyping in the next few weeks. I will keep everyone posted.

Nikolas

do you have a idea for a base price at the moment?

Currently our headers sell for between $350-$400. It really depends on how large the header is and how much labor will go into the fabrication of each. Ceramic coating costs will also go up if the unit is large.


Nikolas

We will more than likely dyno the car on July 17th... We want to get a baseline on Horsepower and Torque before we begin development of a header for this car.

It would be mighty nice if you could share the results of the baseline dyno testing here, as well.

This guy is also pretty well thought of at a Focus board called Focaljet.com, and most of the regulars there do not suffer fools lightly.

Gobstopper,

That is correct about the FocalJet crowd..... they can be rough at times. But, towards those who deserve it. ;)

The July 17th Dyno has had to be called off. a few of the cars we had slated for testing wont be ready by tomorrow. Hopefully we can re-schedule a dyno session for early-mid August.

The dyno session being delayed wont delay progress on our development of parts for the Scion.

Nikolas

Does anyone have pictures of the underside of the tC? I am curious to see the layout/design of the factory exhaust system as well as how the factory exhaust manifold is routed.

Nikolas

i don't know about pics but if you go to scion.com and go to build your own there is a 3d model of the car. you can spin the car and even look underneath it. granted, i don't know how detailed it is or how much detail you need but it might be what you are looking for.

Thanks for that link, it helped me out a little bit and gave me a good idea.


Here are links to pics from a 2.4L Camry... They are about 1MB each, so 56k beware. If someone could post pics of the down pipe, flanges, etc.....just like are pictured here... from a tC, that would be great.

We are hoping that the we can design one header that will support the Scion tC, the Camry and the Solara.

Nikolas

Any news on the header? :?:

We are currently having the header flanges laser cut at the moment. Once we get the flanges back then we can begin fabricating the first prototypes. Im hoping we dont see any delays with the delivery of the flanges.

Nikolas

just curious how the headers are coming.

will the header be of a 4-1 or a 4-2-1 style ? Im just curious, Ive been designing and building headers professionally for the last 6 years and have my own opinions of both, I will also have a TC header available very soon, maybe we can put together a friendly little "header shootout", that would be fun! :wink: thanx Jason

are you also looking to get around the 02 sensor problem becasue of the thermal reactor on the manifold? how is your progress going? :D

My header will also be a "Race Only" :wink: piece, trying to duplicate the thermal reactor would just cost you alot of $$$ and performance, if your talking about setting the CEL , that can easily be taken care of with a few resistors thanx Jason

Great, I just hope the headers that are released fit my 2AZ-FE in my 02 Solara :)

bump for updates

been playing on the dyno a little, trying a few different things, you guys will be very pleased with the results, thanx Jason

How are the headers coming along? :roll:

We got the sample flange back from the laser cutting company and we gave them our approval. We will be conducting a baseline dyno test on the donor Scion tC on November 13th. Shortly after that we should have prototype headers ready to test. We still have a target release date of before the end of the year.

In early 2005 we will be releasing an exhaust system for the tC as well. (I know that doesnt help you Camry owners).



Nikolas

Nikolas, any news on the race headers?

doesn't aem/dc sports have a header too?

doesn't aem/dc sports have a header too?

Yes they have headers too, but I'm not sure if they will fit on a Solara?

Has anybody tried them on a Solara?

I believe the ones that Draxas are making are race headers and will hopefully be better than the AEM/DC Header. :nails:

any new news now? :pray:
