    Shortened antenna, ebay Intake, JBA long tube headers, 2nd set of cats cut out and straight piped, 14" Magnaflow muffler dumped before axle, relocated rear diff breather, Avid off road front bumper. Bilstein 5100's front and rear, OME 885x coils, Light Racing UCA's, 2" Toytec AAL, Hella 700ff lights, Falken Rocky Mountain AT/S 265/75/16 Load E 10ply, Blu Logic handsfree
    I pulled the trigger and ordered JBA long tube headers in stainless steel and URD o2 simulator from URD. I wanted to free up the exhaust in order to gain HP and TQ. By looking at the dyno graph there is only power loss below 2.8k rpm. Above 2.8k rpm the headers SHINE! By 3.68 rpm, there is a torque gain of 24WTQ and 17whp! The headers gain 4whp and 12wtq. I was especially intrigued by the gains between 2.8k rpm and 4.2k rpm which i thought could help when towing and getting up to speed or passing.

    For the price of $468 I paid shipped from URD for JBA headers, gaskets and o2 simulator, the headers are definitely the best N/A performance mod for the 1GR.

    Th JBA headers appear to be good quality. Fit is OK, I was unable to line up the headers with the header support brackets which bolt to the bottom of the header where the header connects to the midpipe.

    One thing to be aware of is that the headers come with four holes for the o2 sensors, you will only be using two holes. The headers don't come with plugs for the holes. The plugs have to be ordered online, they are impossible to source locally.

    Now for the install instructions. Below are Instructions which came with the headers just for reference. I didn't follow these instructions very closely, because many of the steps are unnecessary.

    Now for my instructions;

    Tools needed

    12mm wrench
    12mm socket
    3/8 ratchet
    14mm socket
    14mm wrench
    15mm socket
    15mm wrench

    1, securely jack the truck up and put on jackstands

    2, remove front wheels

    3, remove mud guards inside wheel wells

    4, unplug all oxygen sensors (total of 4)

    5, remove Y pipe - two 14mm bolts hold it to the exhaust and four 14mm nuts hold it to headers (two nuts on each exhaust manifold)

    6, remove 14mm bolt holding exhaust manifold to brace. Bolt located on the bottom of the exhaust manifolds same spot where the ypipe connects to the exhaust manifold

    7, remove nuts holding stock exhaust manifold to the heads of the engine all nuts are accessible through the wheel well (6nuts on each side)

    8, remove stock exhaust manifolds, it requires little twisting because the exhaust manifolds get hold up on the brace at the bottom

    9, remove brace held by two 14mm bolts on each side, my headers didnt line up with the brace

    10, remove old exhaust manifold gaskets

    11, install new header gaskets which came with headers

    12, instal headers and hand tighten all header nuts (6 on each side)

    13, tighten header nuts, work from inside out alternating top to bottom, once all nuts are tight, tighten them again in the same fashion to make sure the nuts are tight and the headers wont leak.

    14, re-install Ypipe, use the nuts & bolts which came with the headers. two bolts & nuts per side they are 15mm

    15, reinstall ypipe

    16, plug in all 4 o2 sensors

    17, install URD o2 simulator, i used zip ties to secure its harness and secured the unit to transmission mount

    18, re-install wheels

    19, safely lower truck & enjoy new headers!

    Now for some pictures of my headers;

    Do you realize that the dyno you posted was for DT headers, not JBA.

    Yes I do. Since they are both long tube headers, the gains should be very similar.

    How do you like them so far? I've heard good things about JBA.

    I like them a lot! There is definitely noticeable power increase past 2.8K rpm. That said headers will make your truck LOUD! My truck has JBA headers, 2nd set of cats cut out and straight piped and 14" magnaflow welded in place of the stock muffler with turn down before axle. It is really loud, but sounds good. It is not too bad when I am easy on the throttle, but when I give it more gas all hell breaks loose :D Exactly how I like it :D:D

    Great post, I love my JBA headers. I honestly don't think I lost any power with them anywhere in the RPM range

    TRD Intake, Borla exhaust,JBA long tube headers, DT Y Pipe, Light Racing UCA's, Jet Throttle Body spacer, lifted 3.5" front 3"back. Grill guard w/ KC lights, Stepsides, Tint, hood protector, window visors, Caltrend neopreme seat covers, weathertech mats, HID fog and headlights, 1" wheel spacers front .5 rear, brakelight guards,265/70/r17 till they die and can get 33's, more to come
    I juat took my JBA long tube headers and DT Y pipe out of the box. There are two O2 sensor bungs on the header and one on the Y pipe on each side,6 bungs total.
    I was just going to use the top bung with stock O2 sensor on top of header and block the other and use the URD sim with the stock O2 sensor at the beginning of the Y pipe. Will that work fine/ is there a better way?????

    Make sure to get two o2 bung plugs, order them now off ebay... They are impossible to find locally...

    The two exhaust rings that urd sends are supposed to replace the two that come with the gasket kit right?

    It can make it easier to get to the header flange nus.
