This is basically how i made my decision - go full catless or get a high quality catted that will guarantee no CEL and pass emissions. Although the other small consideration if you are not in an emission state is the smell. You can get a catted for relatively cheap that will not pass emissions but will eliminate most of the smell.

I too didn't want to be the guinea pig for AA, and the price difference was less during BF sales, so i went fabspeed. Another member here just installed AA so maybe ask his experience? Usually if you are going to get a CEL, it happens after the first few hard pulls, especially if tuned. As mentioned by Jeff and the fact that AA is actually EPA certified, i wouldn't really have any doubt their DP will pass emissions and not produce a CEL.
