Pass smog with stage 2?
I'm currently stock running a Cobb Stage 1 map and i'm about to buy a catless downpipe. Will I pass smog with a stage 2 set up with CEL Fix? I heard about the FOULER trick that I might use, will that help? Appreciate it!
UPDATE: Just finished smog and passed with flying colors. Stage 2 time!

stage 2 map should knock out the second O2 sensor, so you dont get the CEL. But if they are scanning to make sure all the O2 sensors on, and/or do a visual inspection looking for all 3 of your cats, then you'll fail. Bugeyes have up-pipe cat, and two in the downpipe.

I guess I should be safe and just wait to pass smog before I put my downpipe in.

I always get the pre test, it's around $20 extra, but if you fail, it does not go to DMV. Gives you a chance to fix what is wrong and then take it back to test again. Still, like everyone is saying, you will need the stock downpipe to pass the sniffer part of the test.
