    Yup, they are on, and they are awesome. Just want to say thanks to TACOROCK for the all the help. I got to say, truck sounds cool at idle and low RPM, but if I open it up it is a whole different world. Scared the shit out of my wife when I was showing off on the way to gas station.

    Will post pics later when have time...:cool:

    I bought JBA stainless ceramics from TACOROCK. Pretty easy install, besides dealling with tight space. One thing though, getting them from him allowed me to not have to deal w/welding them to the front cats. He had that already done. So that saved me time and money.

    As for sound, I am happy, Not so loud for daily driving, but masively noticeable when I need to get up and go. Mite get URD Y-pipe in future. Waiting to research more on Back pressure specs...

    Feel alot more take off, so I guess the torque definately increased. All around I think they completed my set up. 3 in 1 pkg performance; Intake, Headers, Exh...

    Oh,,, and now driving slow is fun cause you can actually feel and hear the tone of a small V8. I am definately getting attention since the Headers. Intake and Exhaust alone only when getting up on the pedal.:rolleyes:

    Roxspin72: I am offshore and can't seem to remember seeing two sets of cat on our trucks. Am I understanding correctly there is a set up front that connects to the headers then another set in back? The short headers allow you to just bolt up and the long tube require you to weld them? What would be the advantage of long over short? With the long tube would you need to relocate your o2 sensor? I am working nights so I'll get back on around 6pm if there isn't any work to do out here. Thanks in advance.

    Sounds real good Rock! I'd be interested in knowing how the whole setup affects your smog if at all?

    JBA short tube Headers need to be welded to your first Cats. then there is a flange from the Cat to the stock Y-pipe which has O2 sensor port and another set Cats... These can be cut, or replace Y-pipe all together without throwing a code. CEL...

    DT long tube Headers bolt right up to stock or aftermarket Y-pipe, eliminating the first Cats, and possibly rear Cats if you cut or purchase the URD Y-pipe. CEL will be on unless you install the O2 simulators in the port provided by DT.

    Dont own DT's, but heard good things. Like the JBA's, not very loud, stay within emission req. And, will get little more rumble once second cats are gone.

    Note: Most cars I've know'n have stock exh. header/catilitic conv/maybe a resonator/muffler.

    Why Tacoma is runing 4 cats stumps me. When I puchased my Borla cat back, I was expecting Y-pipe include, which would have been the case if Toyota did not put unneccessary cats there. Madrel bent piping is the benefit for aftermarket exh system, and the worst bends on the Tacoma is at the Y-pipe...

    Well I think I said enough.........

    hey bro, i put the headers on Roxspin72's truck they were my headers originally you have a total of 4 cats on your truck 2 per engine side/exhaust manifold: off of your block it goes like such...... DRIVERS SIDE ( stock header have 3 port flange half of the v-6 6" back you have an o2 sensor the same for the passengers side 4" after the o2 sensor you will have a cat on each side) 4" after the cat you have an exhaust flange which connects to the y-pipe. that is the end of the "header" on both sides. from that flange 6" back you will have another 02 sensor on both sides. then a second cat on each tube coming off of the headers. then they connect at a y flange and go back to the muufler and to your tip.

    shorty headers: will require cutting your old cats off stock headers and welding them on to the aftermarket "SHORTY" headers.
    pros: you will remain state emissions legal this route! advanteges ported a little wider from the header flange and conjoin all 3 ports into one as a sucking/synchranizing all 3 ports on each side.
    cons: usually expensive and not as easy as you think even if you are an exerianced welder.

    long tube headers: same length as stock headers to include cats.
    pros: bolt on and eliminates the front cats usually cheaper. largest hp gains.
    cons: used for off-road use only. not emissions legal. you can purchase a bypass to your computer though. to make anyone who is inspecting you for emmisions think differantly.

    for both setups your o2 sensor stay in the same location
