Been a little crazy lately with the holiday. BUT YES!!! We need 20 people. I've been very involved in discussing this project with DT and trying to make it come to life. DT does listen to customers and listened to me as a sponsor on here about doing this test. I said I think it's good idea at least to try ONE RUN and got the green light, again, need 20. Very cool. These prices I also worked on and are very fair! I know what this stuff costs to make, and those that know also should be happy.

(flanges, air tubes, welding, tubing) stainless headers.

03-04 Shorty headers - Group Buy $719.00
05-09 Shorty headers - Group Buy $855.00

03-04 Long tube headers - Group Buy $765.00
05-09 Long tube headers - Group Buy $899.00

In just a few days already have 5 people. Let's see if we can do this!

EDIT, there needs to be 20 total for LONG TUBES ONLY to make this happen. Doesn't matter if there are 100 people that want short tubes, 20 is the magic number that we need for LONG TUBES only. (The collector flanges must be bought at 20 sets to get the discount we need behind the scenes) So, as long as we get 20 people for LONG TUBES, any one that wants short tubes will be able to get short tubes even if there are only say 5 people than want short tubes.

Edit #2 Yes, these will also fit the GX470, 03-04 and 05-09. Same thing, same headers work on BOTH! Spread the word!
 
New member here - anyone know if there's any way to pass emissions in Colorado with the LT's? Also, is the shorty version a PITA install if I want to go 2.5" and maganflow hiflow cats behind?

All that said, I'm acquiring a '06 Limited V8 in 2 weeks and I know I want this done so put me down for a set of shorties please...

Based on a quick look at the web, it seems like in Colorado you have to do more then just pass the OBD and gas cap tests for a vehicle of that year so it seems unlikely you'd be able to pass with the LT's. I just passed emissions in AZ with the LT's with the 02 sensor spacers cause we only have to do the 2 two tests I mentioned. If you have a family member or friend living in a rural area though you could register your vehicle to that address and not have to pass emissions, or atleast that's an option here. Hope this is at all helpful.

So are the long tubes just bolt on and go with no welding? Obviously studs break, but other than that they will just bolt onto my OEM y-pipe?

Considering joining this...
 
Ok, well, I think we only need 5 more for long tubes to make this happen. This is going much quicker than I thought it would....

So, we need 5 more guys for long tubes....
 
Oh man, I just joined the forum for this group buy, someone mentioned it in r/4runner, but I'm looking for the Shorty Header for my 05 V8 because I plan on moving to Colorado...

Can you weld the stock cat onto the Long Tubes?

You can... but I wouldn't advise it, be better to just buy some Magnaflow highflow Cats through Jason to squeeze out some more power and they'll last longer.

Do these require any kind of tune? I don't care about performance increase, I care about longevity and prefer a quiet exhaust if possible with no drone.

As [MENTION=268835]K-D-Runner[/MENTION] said, I'd recommend the Magnaflow high flows cats, these will give you an extra 7 HP per cat over the factory cats! You can order them from me and they are super inexpensive. Call or text 717-319-2100

Nope, that's the best part. No tune is required or needed (but we are working on a tune that will give another 15-20 hp! stay tuned). And these headers will actually give your exhaust a more smoother/quieter sound after installed, plus the 3-4 more mpg highway (on stock tires). My other customers with 3" lift and 285's, about 2-3 more mpg highway.

Who you working with on this tune??
 
Just a heads up, [MENTION=112299]Formidable[/MENTION] sold his 4R. I’ve been following this thread because I’m happy with how it was handled on DT’s end and this extension of that. I have a V6 or I’d be down lol.

I’ve been in touch with Doug Thorley and I may be number 20 if we can make this happen. Full SS!
 
where in CO?

Denver area.

I thought I had to get the Shorties in order to fit a cat on there. I already have an after market exhaust from cat back, how much more modification would I have to do in order to fit the Magnaflow cats?

And at what price with this group by allow me to get the Long Tubes?

Essentially, I want to know an estimated price on what it will cost me to get the Long Tubes with the Magnoflow cats on my '05 v8 that already has after market exhaust from cat back.
