Anyone know of a good place to buy JBA Headers for a 2005 Tundra? Also, has anyone installed them on their Tundra? If so what kind of results have you seen?

Reason: Looking for specific info.
VVTi is not a feasible mod for most folks. Believe me, when that was introduced, the first thing I asked was: "Can I do that to my '03?"
I'd love to know the steps and parts required for a VVTi mod on a pre-'05 2UZ-FE! I bet it would be expensive. Probably cheaper to get a wrecked engine, ECU, etc. from a newer one than to mod a old one for VVTi. At least that is what the guys I asked said.

Yes, and as I stated, said headers offer "not as much gain with a VVTi", meaning JBA headers offer less performance improvement when used with newer VVTi 4.7 engines than they do when used with older non VVTi engines. The original poster has an 05 (VVTi), so he might be interested in this.

You thought "not as much gain as a VVTi".

Oops. That was not clear from your original post. It read to me, like you were suggesting that VVTi would be a great performance mod, which of course, it would.
I remember a thread about 2-3 years ago, where they were developing a computer chip and IIRC, it was even a group buy. The manufacturer's tests indicated a similar experience as you suggest, that if you have "breathing mods", i.e. performance intake, headers, and exhaust, the gain from the computer chip mod was limited. Whereas if you didn't, the chip mod would wring out a ton of extra performance.
Sorry for misreading your intent.

JBA themselves, and several on this board. The VVTi headers have half the torque gain as the non VVTi headers. I would still buy them despite this, as there is still a gain, but my main issue with them is price.
Thanks Mike. My main issue is that I have a 24' enclose trailer loaded with tools. The truck pulls the trailer pretty well but I think it could be better. My guess is that the headers would be perfect to give the truck that little extra pulling power. Its either that or buy an '07 Tundra, but the one I want is just about 50k. Think the headers would be cheaper.
I am also considering installing a Cool Pak electric fan. The manufacturer claims more horsepower and torque. Also, I had an e-mail response from them that claimed a fuel savings of 5mpg. Any thoughts?
I think the 05 uses a thermostatic clutch type fan? These are OK as long as a proper shroud is used. I doubt switching to an electric would offer such a large improvement in mileage.
What is the nature of your towing difficulty? Getting the load rolling from a stop?
From being on this board and reading threads for several years, these are the performance mods that I would expect to get the most performance from (on my '03 - not sure as relates to VVTi) in order from most to least:
Headers & Y-pipe
Performance cat-back exhaust
Underdrive pulley
Electric fan
Performance intake
Ram Air Performance System
Performance air filter
Notes:
2. such as Borla, Bassani, TRD, etc.
Between 3 & 4, I don't know which wrings out the most HP/Torque
I wouldn't do both 3 & 4 unless you have the towing package which usually comes with the heavier duty alternator, since the underdrive pulley would reduce its effectiveness some
5 & 7 are mutually exclusive, i.e. do one or the other, but 5 probably will get slightly more HP/Torque.
6 probably helps more on highway speeds because it forces more cold air, than at stop/start
I am not sure which ones will help with towing the most, since you really need torque there, but most of the time, and increase in HP will help increase the torque, although not accross the RPM band.
IIRC, the JBA headers boost the torque at lower RPM than some other brands, which would be desirable for towing.

Mike, not too much trouble towing. The truck seems to have plenty of power, but I at times I feel like I am pushing the truck to its limits. Also, I haven't had to tow the trailer up a long steep grade yet (not too many in Wisconsin). I think when this day comes, the transmission will probably kick down and really work the engine at a high rpm. I think with a little more horsepower and torque the truck will have that little extra it needs. Which brings up my more recent issue. Invest money in my '05 or save the money and put it toward an '07 or '08 CrewMax with 100 more horsepower and ftlb's of torque, factory tow mirror, larger towing capacity and the option of a backup camera. I love my '05 but I think I'm heading toward a new CrewMax.
Best Prices on JBA Headers?
