    So I've been trying to do research on the feasibility of installing a supercharger. I was wondering if installing a supercharger still kill the catalytic converters that come with the trucks. I've seen older threads about them being killed, but wasn't sure if this has been eliminated or alleviated.

    Living in North Carolina I know we have emissions testing, but I'm not sure if we're doing the sniffer test or just plugging in the obd2 to ensure that the system is ready for operation. What I do want to find that if I do it's all a supercharger, do I need to remove the cats and put straight pipes in, or can I run the factory exhaust manifolds and cats.

    I've not heard of a supercharger shortening the life of the cats.

    The Magnusen SC is California compliant.

    As long as you don't have a CEL, the truck is not running open loop and feeding a rich fuel mixture to the engine, thus loading up the cats.

    I didn't even think about that, but you're right. Thank you for that.

    The tune determines whether or not the cats survive.

    Cats cause better low end torque when supercharged. But they do not lose low end torque. If you can, you should use cats.
