    Can you still pass inspection with these? I know deleting the cats isn't legal but is that what the 02 sim is for?

    I will be able to give a little insight as to the difficulty of install in a couple weeks here when I put mine on. Can't wait!

    The O2 sensors read catalyzed exhaust gases. When your remove the cats infront of them, they no longer read that. Thus the check engine light is turned on.

    To trick the sensors into "believing" they are reading proper catalyzation, the O2 simulator intercepts the signal and returns the proper signal back to the ecu. With the URD plug n play O2 simulator, the O2 sensors must remain in the exhaust.

    There are other brands, where the sensors can be completely removed.

    As long as you keep the factory y pipe on, you "should" be able to pass visible inspection since you still have two cats.

    i have them and love them. just make sure you get a big muffler(magnaflow) other wise it will be very loud and raspy. i have a 40 flowmaster. i like it loud but this is alittle to much. sound like a old man farting in a can when you take off.

    The blowmaster is your fart can problem... I am hoping that I get a good sound out of mine, and if I don't then I shall tune it like I have already done to my current setup.

    AEM bruteforce cold air intake. doug thorley headers. flowmaster exhaust. HID kit heads and fogs. "Taco" badges. black vinyl roof. plastidipped grill and rear bumper and 3rd brakelight. headlight mod. 7" alpine touchscreen head unit.

    i have had the doug thorleys for like a couple years now and i love them. you will notice big gains in 3rd gear and up. i have the flowmaster and it does sound like bees in a coffe can. but only when my truck is cold. i am looking into the o2 sims because my cel has been on since i put the headers on. and going to upgrade my muffler. been thinking about straight pipes.

    In talking with a local shop they were relaying to me that headers will increase the temps under the hood there by wearing out gaskets and parts. Thoughts on that? I thought it was supposed to be the other way around.
