" Default Re: JBA Headers.
The 5.7's use oem gaskets. We are working on some very Hot stuff at the moment that everybody in the Tundra world will appreciate.
hi, i have a 2005 4.7 . i had JBA 2011s installed last monday. today i was at a light and steped on it. it spun the tire. that never ever happened before. i know it was because of the JBA headers giving me more power.i highly recommend JBA. use OEM manifold gaskets.if you seen what the OEM manifold's(header) look like compared to the JBA, toyota should be ashamed of themselve's for making such a poor product. i highly recommend JBA. it does cost alot for the headers, another set of oem manifold gaskets and the professional installation. but i know it was worth every penny i spent.
i am so happy now. i have a K & N cold air intake, JBA headers, and a magnaflow muffler with dual tail pipes out the back.
the truck sounds so mean, i am so happy. i wish i knew how to get the Y pipes ,so i could eliminate the cat's. and not have OEM sensors going off. i heard that would make it even louder and even more powerful.

Well I called my dealer today and asked if they would install after market headers on my truck. They said no at first because they didn't have the equipment to wield one on. I told em it was a bolt-on, they said they would have to check and see and would call me back tomorrow. I hope they hook me and I hope they know what they're doing. Who better to install then the dealer......right? lol

Do it yourself - after all the worrying about how much harder the 5.7 tundra header install appears to be than the older tundras, I convinced myself otherwise from other people's experiences and from installing a set on my neighbor's DC a few weeks back. They're not that hard to do. It took us just over 3 hours to do. I was very surprised, as it was easier than it looks. The JBAs appear to make some decent power gains in the upper RPMs, but still improved the low end somewhat despite not being a 4-2-1 design.

Me and pops may give it a go. Are there any special tools you needed for the job that most people may not have? Thanks for the advise

Just a really good assortment of swivels and extensions with lots of different style sockets will do the job nicely. Just take your time and have patience with it. Undoing the engine mounts and jacking up the engine a bit helps a lot - use the old wood block under the oil pan trick. Pulling the front wheels helps too, giving you better access. I took some tips from the doug thorley install thread, which is pretty much the same process.

Thanks for the tips, since dealer has called back and quoted me 12 hours at $900 I will be trying this job myself. I did fax them over a copy of the install instructions to see if they could do a little better though.
It clears all the short and long term fuel trims and learned sensor baselines. To answer your question - yes it does, but it will learn faster from a hard reset than from readjusting existing learned parameters. Reseting the ECM can also avoid the likelyhood of a CEL, which can be triggered by an abrupt change in a sensor's reading from the installation of a bolt on part. Any change in airflow made to the engine (intake, exhaust etc.) should be followed by disconnecting the battery for a hard reset of the ECM.
All that having been said, it's not impossible to teach an old dog new tricks but it's definitely much harder
Well, I thought Id posted a thanks for the info, but I guess not.
Thanks for the info.

Well my dealer called me back, looking at 7.5 hour install at $525. Supposedly they looked it up on the internet and researched it. That's a lot better than $900 but I think I'll stick to trying it myself first. I also called JBA and he said something about there will be an independent magazine running a dyno. He said he couldn't remember if it was Truckin or Hot Rods and HP. Either way I'm looking forward to it.

Taking your sweet time, you should be able to get them installed in under 5 hours. My motto is "access is key" - that means I'd rather spend 10 minutes getting stuff out of the way instead of it taking a 1/2 hour working around it. One really good thing to have is a vast assortment of 12mm 12 point wrenches, especially the ratcheting kind. Having a set of ratchet wrenches is the best tool investment you'll ever make
From my own experience I always like to emphasize taking your time. I have the tendency to be a hot head when something goes wrong working on a vehicle (ask my neighbors ). Just take plenty of breaks an allow yourself twice the given time to get it done.
Hope it goes well

they said the same thing to me last week. I am hoping that we can get something together and do our own tundra solutions competition. I have trouble believing magazines cause you never know who is taking money on the side to inflate numbers. On the other hand I would 100% trust members of this site to tell the truth.
Your 2005-4.7 isnt anything remotely close to the 5.7 platform,glad your a happy camper from your investment but please stick to apples to apples.

i will contest many things.
1 the computer is relearning.
2 throttle response is immediate,powerful & aweseome
3 it is getting better and better every day, the more i drive it.
4 low end ,mid range ,and top end is ALL better.
my truck is louder , faster, and a much better throttle response.
if you look at the stock headers and match them up with the JBA, there is a huge difference. my installer said toyota should be ashamed of themselves. making such a poor product. 3 of the ports come out and go into 1 pipe. there is only 1 long pipe.
all the JBA are all the same size coming out of each exhaust port.
and such small size pipes.
i might have named a few things wrong, i don't know the technical names for everything.sorry.
but i do feel the difference.
and in my opinion worth every penny i paid for the headers and the install.
1 thing that is so very important.
i read this and went out and bought them for the proper install.
i would say no matter what type of headers you purchase, by OEM manifold gaskets!!!
### please buy the oem manifold gaskets ####
other wise you will be re tightening every month.
