Feeler TRD header

[xnamerxx]

Feeler looking at selling some of spare parts I don't need.

I have a genuine authentic TRD header for the Yaris that has less than 400 miles on it. This part is pretty rare and really hard to come by asking $440.

ooo thats interesting never even knew about them... waiting for pics

[Jason@SportsCar]

The unicorn of exhaust manifolds. They are sure proud of that piece, 88,000 yen - or about $870. :eek:

LOL at 'unicorn' - so true.

[BEEF]

What's the random pipe coming off of the base just opposite the 02 sensor?

[1.5]

wow I want that solely for the fact that its so rare and authentic JDM lol this should go quickly

[xnamerxx]

It appears to be an EGR tube that capped off, its closed off and not hooked up to anything. It doesn't get in the way of anything its just there.

Does it look like this, or is it capped off where the corrugated pipe is on this one?

Exactly where the corrugated tubing ends.

That is really wild. Looking at the JDM EPC, the Vitz with the INZ gets a stock manifold with that same hookah attached. There is nothing that attaches to it though. According to one of the documents that I found on the TRD manifold, it is supposed to add 10 HP and 4.3 ftlb torque (when used in conjunction with the TRD exhaust and TRD intake).

What is the purpose of that funky piece? Could this outperform the DC headers you think.

[xnamerxx]

That tube was originally for an EGR tube, but as the Yaris 1NZ-FE doesn't have EGR it was capped since its not needed.

I can't say for certain, I wasn't happy with the DC header I had because of the of low end torque I lost, but I can say this the TRD piece is an equal length header with really nice mandrel bends and nice tig welded joints.

[marcus]

nice..

[tooter]

It's interesting to note how they curled the equal length runners around each other to make them as long as possible while still occupying the same end to end space. That is a beautifully designed product! :smile:


Oooh... found a good pic of one except without the EGR! :smile: That pipe could easily be removed and welded shut.

The header on my truck used that same equal length design to get longer runners into a shorter space..

Just based on the tubes being equal length I think the TRD unit would have a slight edge over the DC.

I agree. The slightly longer equal length runners would give it tuned resonant frequencies where the exhaust would scavenge better at certain rpm ranges. I'd love to see a dyno chart for that header! :drool:

What's the diameter of the tubes? Gosh that trd plate on it makes it look so good. Wish it was visible for third party viewing haha

Daaamm...

Lsd or trd header...grr

[Klink10]

Couple of questions.....Why the sale? Did this give you an improvement over the DC in the low end torque area? Price include shipping? Very interested.

[xnamerxx]

Selling the header because its not legal for class I'm racing. It was on my replacement motor and since I can't use it I figure it would be better if someone else uses it rather it sitting on a shelf at my house.


Don't have any dimensions on this but I can get some on Monday.

[1.5]

You know my birthday is 2/19 ;)

[Klink10]

Thanks for the response but still.....did you run the engine at all with the header installed and did it make an improvement on the low end torque vs the DC. Just curious how you felt with it.

Thanks Garm.....however this is the statement that prompted my question. The highlighted above made me think that it was run and thus my original question.

[xnamerxx]

I run long tubes in my stf car low end isnt a problem now. No idea how the TRD header feels never drove with it,that motor is going into a b spec car.

[ToyotaBuzz]

I run long tubes in my stf car

Really? Which header?

[xnamerxx]

One I built and designed.

[e_sabellbat]

Im using TRD Exhaust Manifold part# 17100-NP100

Nice... i always wanna have those...

[Klink10]

XnamerXX- you have mail.

[1.5]

xnamerxx i remember you sayin you were going to try and R&D some long tube headers. Are you only making the one set currently on the car? I would be interested in them if youd like to go into a small production.

[xnamerxx]

I've build a few headers, but its not really something I could sell. I don't have a full exhaust design so the header in and of itself is a hard sell, that and the production cost of the header is pretty expensive.
On the last header I built the gains were hugely impressive to say the least but I don't think I could even market it because the material costs were so high.

[xnamerxx]

SOLD!

Ok well maybe we can talk about you making another one off piece for me?

SOLD!

Dang I was hoping it might linger til I could drop the money on it.

[ToyotaBuzz]

I'm with Phil. Lets get some numbers on a long tube header.

[1.5]

GB with me and Buzz

[xnamerxx]

I could probably reproduce a long tube header for about $800 give or take, if I make it out of mild steel. This would be a header only and not a complete exhaust.

[Jason@SportsCar]

I doubt you could find any company that could build and sell a long tube for the Yaris for under $1500, the volume simply isn't there.

I looked into it when I was starting mine, and the cost to be the first unit was just insane - it would have required selling about 25 units just to cover the "R&D" with the vendor I spoke to. And what was really lame about that was I was bringing the design to them. Instead I sourced the parts, and design specs, and had xnamerxx fabricate it. Still would be extremely costly to replicate.

These are also not a bolt on affair, so you are modifying the rest of the exhaust to make it fit.

But it sure is pretty and makes some great numbers.

[xnamerxx]

Yeah basically what Jason said, when I initially made my first header I looked into having the tubes recreated, I needed 75 bend minimum order, for them to even take the job. The initial run was going to be prohibitively expensive to bring into production so I decided against it.

[1.5]

I currently have a custom straight pipe exhaust fab'd by my local exhaust shop. Due to FL laws apparently you can only delete the cat if the car gets trailered in so they chopped it for me right after the cat and welded there.

From my experience, most LT/race headers cover the span of the piping past the cat with either a straight pipe or a hi flo cat. That would mean I could probably fit the LT header with minimal hacking of my current exhaust setup.

If gains are as positive as you say xnamerxx then $800 could be worth it but i doubt $1500 would ever be worth it lol

[ToyotaBuzz]

I'd really like to see dyno charts to realize the cost-benefit-analysis. $800 is no joke.

[xnamerxx]

Thats what kept me from making more. The gains were not enough for me to justify making more because of the expense.

On my motor I saw a roughly 6 hp gain at peak and a 5ft torque at peak. But those numbers only tell part of the story, At 2k I saw almost 15tq and +5min throughout the entire tq band. Now those numbers are already on top of a DC header, so its not exactly stock gains.
All I can say is that I love the header so much I spent a great deal of money figuring out how to get the stock muffler to mate up with it so I wouldn't have to take it off.

[ToyotaBuzz]

You have a long-tube header mated to a stock muffler? My stock muffler was SOOO restrictive on the HP when I installed my weapon-R and Nitto mid-pipe. Butt dyno was enormous after installing my TRD muffler.

[xnamerxx]

Yes the car doesn't feel as peppy when I run the stock muffler after 5k, but most of the time it really doesn't matter, I'm almost never above 5k and what I really care about is low end grunt. After I installed the header I almost never have to downshift in traffic, because I can lug it in 5th without the car feeling like turd.
When I'm racing that's a different story but truth be told I'm still almost never above 6k and more often then not I'm between 3-5 which is where I want my torque band so the car moves.

Is it possible for you to post the chart for your header so I could compare it to my baseline dyno?

Thanks,


Greg

[xnamerxx]

I'll post my old dyno, but its not an apples to apples comparison. New motor makes more power, but I don't have a copy of those numbers.

Greetings, still these headers 4 sale

[justjesus]

^ it appears to be sold, Car Freak. On page 2.

the thread turned into a header talk :)
