    Does Anybody know if removing the cats kicks a check engine light? And also would it make it impossible to pass smog/emissions?

    Yes to the check engine light and yes you WILL fail emissions testing as you will have no emissions on the vehicle.

    Possible, yes. There are ways of not having it trigger a check engine light but these are for "offroad only" since having a catalytic converter is a federal law I believe for road vehicles. You won't pass emissions or a smog test unless the techs are dumb, or, you are paying them to be dumb.

    Thanks guys. I ended up taking it into a muffler shop instead of doing it myself. They said that i shouldn't remove the cats because it would kick a light and the truck wouldn't run properly because the engine needed the back pressure at its current tuning. Thanks for the answers though guys.

    Of course a muffler shop will say that. If you get the downstream o2 simulators it will be fine. Backpressure is not factored in tuning its incoming air. We have done cat delete's on everything including S/C Third gens with headers. It will defenitly get louder.

    It was nice before 1996 when you can just gut out your Cats and get away with it. Jap cars mostly because they run clean already. So one thing I hope to learn hear is how to put dual exhaust on a 2000, V8 and be able to gut the cats. If I have to leave them, then at least dual exhaust with some more flow. I don't know about you guys, but I'd rather breath gas fumes than Sulfur. Isn't Everything living made from carbon, so go figure.

    Get some 02 simulators or if you want to be really ghetto you could attach the 02 sensors somewhere outside of the exhaust stream.
