Just make sure you have a cat. It's illegal to not have one. Or find a place that doesn't give a crap about it.

you should pass emissions.. run an exhaust with a high flow cat and be good to go..

with tom's tune you wont throw and codes and you will still have a cat if they do a visual inspection, and you should pass a sniffer test.

i pass emissions with my turbo and only the high flow cat :)
