I'm getting all antsies in my pantsies.

Kent, have you installed these? How long would it take an idiot to install them? I've never done anything this serious.

 

I would love to add these and the TRD exhaust to my truck!!!!

 

Everytime i click on the "Doug Thorley Headers- 4.0 1GR" the hood strut pictures comes up...hopefully that will get changed.

 

works for me, let me know if you still have issues.


edit- and yes, to the people who asked, a full website update is coming:lol:

 

So, not to poop on this GB, but this doesn't seem too extraordinary. I looked at the URD website and they are selling the Thorley headers for $529. However, they discount their dual O2 simulator to $59 (normally $89.) So, it looks like you are really saving $10, unless you don't plan on buying the O2 simulator from URD. I don't know what the shipping expense is going to be, and that could be significant.

What am I missing?

Well, for starters....

But this time we were able to get them for $490 plus $30 shipping to the lower 48 states

 

Not sure about your shipping but c2c said $45 to ship and urd says about $23 to ship to my door. I see a xmas present to myself coming soon! These would look sweet under the hood, so glad the went to cermaic instead of chrome.

 

as said in the thread, shipping will be 30$. the 45 only carried over from our last group buy. these are being drop shipped, and DT gets a nice discount on their shipping.

also, retail on the headers is 541. URD DID sell them for 529, but i am the only dealer you can buy these from now. even if you try to buy them directly from doug thorley, they will forward you to me. i will be offering an O2 simulator before the group buy ends hopefully very cheap to the group buy people. 490 is a pretty damn good deal on these headers, ill bet anyone a box of donuts they wont see them again cheaper

 

What about those of us who were on the last GB? Can we get special pricing on the o2 Sim as well?

 

If you click on the picture you get the right info, if you click on the words underneath you get the info for the hood struts. So who is going to be the only dealer for these now, C2C or URD?

 

thanks, ill get that fixed. oh, and C2C....

 

I'm definitely in on this...I'll be placing my order tomorrow.:banger:

 

Smokin' deal. Don't think I can scrounge enough change from the couch that quick though. Did anyone that bought them in the last GB dyno with other mods like intake/exhaust? I would like to see what an N/A tuned package could bump out.

Big plug for these headers, install is easy, they look great and do perform!!!

This is w/ URD Intake, MAF(12.3 afr in open loop), Ypipe, o2 sim, and magnaflow 24'' muffler
Two dynos here, only thing added on the top graph is c2c headers. No other changes, tunes, etc
Peak #s: 297 rwtq, 252.6 rwhp

Your exhaust will be WAY too loud with this set up..I recommend keeping the stock Ypipe if you have an aftermarket catback exhaust. Running 2 straight thru mufflers doesn't do much for noise levels either.

 

I've been waiting for this, count me in for sure. :clap::clap::whatwhat::whatwhat:

 

Dummy

I don't know much about all this performance enhancing equipment but say I buy the header..........

1. How much would I expect to pay to have it installed? Say I buy only the header for $520 and it costs me $160 to install, do I get the additional performance listed with everything else still stock? I guess the cost per horsepower goes up when you add the installation cost.
2. Whats the O2 simulator thing and do I need it to get the performance advantage indicated?
3. Most things I read indicate if you increase you exhaust, you need to increase your intake...so if I bought and installed the headers, do I need to do additional mods under the hood? I've heard good and bad about K&N and I run some dirt roads frequently.
4. Do I need to couple the headers with a new muffler system like the Flowmaster Series 40? It would seem that if you only reduce pressure from the engine half way back to the tailpipe. you haven't done much.
5. Whats all this cost?

1. for a qualified installer, its a 1-2 hour job. prices vary everywhere, check what the going rates are.
2. on 02 sim basically tricks your engine to thinking all cats are working 100%. without that there is ZERO loss of performance, just an check engine light.
3. you no not need to do anything else. the dyno and horsepower given in the first post are on a 100% stock truck. if you were to add intake, and a cat back, you would gain more power, but its by no mean "needed" as they perform excellent by themselves.
4. again, you dont have to. you will find some additional power, but it is going to be small gain in comparison to the power gains of the header.
5. it costs as little as 519, and as much as you want. if you are looking for performance, this is the best bolt on out there. if you want a little power, and alot more noise, couple it with intake/exhaust.

there are only 35 sets ready to ship, and i expect them to move quickly, so if anyone does want them i would suggest getting payment in and holding your spot

Alright...I give up. I'll get it. I'll have to wait until Friday...I hope you don't sell out!

 

I know it is officially open tomorrow...are people being allowed to order today?

 

mountain lion i am a little mixed up, is the only difference between the dynos headers, or all the mods you listed?

 

only headers, everything else was already there / unchanged...keep in mind this shouldn't discount the dyno shown up above in terms of gains...that was done on a completely stock truck, so i'd expect the gains to be a little less on my truck since the system was already opened up with other mods.

 

Just placed my order, early Christmas present to myself along with the C2C hood struts and TW Driveshaft.

 

What material are they made out of? 300 stainless, 400 stainless, carbon steel?

 

Mild steel
14 gauge
ceramic coated inside and out
3/8 flanges at both ends.

 

Oh Damn! Looks at the CC! Dammit...
Theres only 15 spots, howcome the post says they're 35....

 

no, the minimum number of spots is 15- once 15 orders are made, the order will ship. the maximum number is 35 for the group buy.


everyone that has bought the headers will be able to get the 02 sims (assuming my supplier comes through.....) at the discount for the question above.

i will have sound clips in a day or two of them on a stock car.

I have the banks exhaust and TRD intake on my truck now. How loud do you think it would be with these on? I do a lot of thruway driving... I don't want it to be so loud that I can't hear myself think. That being said, those numbers are impressive!

 

how loud is it now? as long as you keep your y pipe with both cats installed, i would not think it would be too loud for you. if i had to guess, 10-15% louder at WOT, cruising shouldnt be changed too much.

jon

 

gotch ya...... thanks for the quick reply. Cruising speed is what I'm worried about. My truck is a 5 with 10 being deafning loud during acceleration but at cruising you can just hear the exhaust.

 

exhaust clip. stock with the headers..... on an xrunner exhaust (slightly louder than all the other tacomas) with a URD intake on it.

Christmas present! im in on this.

 

Just ordered mine. Shipping charge was $45...thought is was supposed to be $30 per earlier posts.

 

i fixed this for you.


about the 02 sim. right now urd has them for 89 bucks- sometimes cheaper if they put them on sale. the headers come out with out any issues (large engine bay:clap from the bottom. its only about a 2 hour job with a beer break or two.

jon


the faster everyone jumps in, the faster we can get the product out:thumbup:

 

Don't pay until they get the shipping price adjusted on the website. Just wait.
