    Well, check engine light came on the other day as I start the truck up to leave work and I am like WTF? Took it in and hooked it up and the machine came back with PO420 (which is catalytic O2 sensor code). So... Do I just cut the fronts out? Or what do I do here, could I actually have a problem? I have noticed no negative changes in the trucks performance since I got it.

    I am not a huge fan of the DTLT's... Simply because of the rasp that is associated with them (otherwise I would be all over it). Really wish XRunnit would hurry up and come out with something... Feck!

    you just have a bad cat, most likely, or a bad 02 sensor...if you have a bad cat, the repair costs will most likely be as much as a set of brand new DTLTs

    EDIT:
    or not...

    In the mean time you could try spacing out the rear o2 sensor with a spark plug anti-fouler. They come 2 in a pack and you drill on out to 1/2 inch. Place that one on the sensor. Then screw both of them into the pipe. It slows down the flow across the sensor thus not tripping a code. You can get them at your local auto store. It's a $10 fix temperary or permanent, till you decide what you wanna do. GL
