I was just about to order and install the RSC cats, ECU reflash and filters on my 2007 AMV8, when I was informed by the dealer shop foreman that the modifications will not pass California Smog testing. Has anyone with these modifications had smog or emission testing done and what has been your experience? I would REALLY like to add these modification and get more HP, yet I also need to be able to pass smog testing. Thanks

 

I'm not in Cali so I can't comment on that but I have all the components you mentioned and it was not a problem in Georgia. Also, I have yet to hear anyone post a problem with emissions after installing the RSC components.

 

You'd have to ask Stuart to be sure, but I'd say the cats will probably be an issue in California. Everything else should be fine.
