    To be fair, the TRD tubes are really considered a mid-length tube that can still use the OEM cats in their present positions (after some welding). The long tubes, like Doug Thorley's etc require either the removal or the custom placement of the cats.

    I have no problem with repositioning my cats for real long tubes, will it still pass smog if you move them tho?

    Stan's are true long tubes and will require moving the cats.

    Everyone who has run long tubes and relocated the cats have had problems with the CEL which I would guess would make it difficult to pass an emissions test.

    Damn. Why would the cel go off if the o2 sensors are still there? And couldnt you just clear the code so when you went to smog it it would be off?

    the cel fires because the temperature varies from when it's in it's original location. something to do with the voltages being inconsistent. you may want to read this post to give you a better understanding. http://www.tundrasolutions.com/forum...-system-works/ by escondidotundra. it's a very good article and definitely worth the read.

    i have a set of long tubes i have to install soon if i can help it. i plan on using my factory cats along with the o2s. escondidotundra made me up a bung to try and "fool" the ecu. hopefully it will work.
    i will post my progress once she's in motion.

    Yea. Thanks for all the help, do you know if your going to have to retune your computer to work with the headers and if putting these on will affect the compression?

    Bummer that they're shorties though. In all my searching the only long tubes I've found is Pacesetters.
    2003 Tundra SR5 TRD AC, Bilstein 5100's top notch, diff drop, ES steering rack bushings, Wheelers single leaf AAL's, Pacesetter longtube headers, stock cats, Magnaflow 12586's (No CEL's!).
