Interest in Custom built 4th gen V8 4.7 Doug Thorley Headers

[TTurner]

I think I would like to see them in a cat'd version. I would definitely be interested if the price was right. I have an 06 and it is the 2uzfe motor. Do I have the motor that y'all are talking about having manifolds made for?

Yes, sir!

Non-VVTI SOL? :toilet:

I'm interested and I'm in So-Cal, Just would be difficult for me to part with the 4Runner for however long they would need it for. I would probably have to buy the headers and get them installed after my 80k emissions warranty expires though.

I would need them California legal, so either they be short tubes and we have to weld on the stock cats or they come with cats. I could always get that kit from URD to simulate the O2 sensors, just not sure how that all works with Smog testing. Long tubes on these 4.7 V8s would be awesome, I just need it to be able to pass smog every two years.

From what the people at DT are saying is: if we could get at least 25 serious people, all with the same model rig's, all agreeing on with or with out cats....and they would need a "test rig" for that certain group of people. They would make them.
So are 03-04 people SOL, if there are 25 people with an 03-04 4Runner then maybe they would make those too.

FWIW the performance gains on the 100 were dyno proven and quite impressive.

I would be in as long as I was assured that this would be a no brainer replacement for 2008 OEM. jdk

Same here. I'm interested for my 06 V8. Would the proper application be true duals afterwards or tie into single collector? It would seem ineffective to have headers and then go single out the back. Thoughts?

im in for the test rig as well. i live in orange county but i am in the military and i am stationed in san diego. i live like 30 min from where doug thorley is located. they just have to be CA legal and i have to be able to pass smog.

i could give them my truck for a while because i could just ride my motorcycle to work.

Deifnitely interested. I have two stipulations though. It has to be able to pass visual inspection, and pass a dyno emissions test here in Colorado.
:reddance:

 

[daPitbull]

Im in, Ive got a 08'. Agree with eveyone else, I will need to pass smog.

With labor you are probably talking $2500...

Parts alone though you can purchase Toyota OEMs for around $650/side. Again, I would be willing to bet they will crack eventually too though.

I was talking about just for the part.

I could be mistaken but I thought it was $2500 for only parts and $3000 installed. Also keep in my that parts are more expensive up here. I heard lots of people replacing dash bulbs for under $5 at dealerships where the cheapest bulb I can get at a dealer up here is $6. Not really significant difference but still.

Well it turns out, unfortunately I wasn't mistaken and we get screwed up here by Toyota. I realise this looks like I just made it up on Excel, but believe it or not this is what the parts guy printed out for me. Thankfully he is willing to reduce the price by 25% but it will still be over $2000 with taxes. I'm debating on calling a dealership in northern new york to see what their prices are, might be worth it to take a drip down.



EDIT: Just got off the phone with TJ Toyota in Potsdam, NY. They want $806.76 per manifold (says there both the same price...wierd) and $23 for the gaskets so definately worth the hour and half round trip.

I don't know about the rest of you, but in my experience with headers is if you think you have problems with exhaust leaks with your manifolds, you are in for a whole other experience with headers. I have had several in some old cars and never had one that went more than 10k without some kind of leak. I would strongly suggest hanging out at a track and talking to people if you have never used them before. They typically are a royal PIA to install then even harder to keep from leaking. There is a reason you don't see stock headers. I am not trying to be a negative nelly here, but there is no chance I would put headers on a daily driver.

saw each manifold for $500-ish USD on the Dallas toyota website. Look it up.

I agree with you. I cannot imagine putting an exhaust (aftermarket) let alone headers on my 4runner.... I doubt it sounds good first off and the power gains still would not impress me to be honest. I'd rather put the money into a "fun" car, unless of course you have some fun in your runner. Every car I've had so far that I put headers on...well it often wasn't worth it between the cost and power gains.

The noise is cool when it's a car you don't drive everyday but I can imagine my migraines being much more frequent with headers in my 4runner.

I guess if they're cheap enough and the install isn't bad, sure go for it if it's something you like.

I would be interested like the rest as long as it passes smog tests in Vancouver Canada. I've already started looking into some custom made stuff but its big bucks.

This would is great, Thank you. Username "Mr.Banks" is from your area and is the service too and said he is willing to help out with testing as-well, but he would only be available at the soonest late June/July. If there is a spike in interest on these headers, would you be willing to do it sooner?

 

[thebruce]

This is my first post, but I wanted to chime in to say that I would be interested as well. I'm located in the SF Bay Area and would also vote for the legal version.

 

[sponger4life949]

yes i would be able to do this when ever. i just need a couple days notice, and i would like to know how long they would have my truck
