Question emissions performance help

I live in CT and have warranty so i most likely wont be able to do performance stuff but i want to get a information so when i can. i plan on getting the cobb accessport to remap at some point and im sure that doesnt mess up emissions

-what kind of stuff can you do to increase performance without failing emissions?

-do high flow cats keep emissions legal while allowing more flow (hence high flow) to produce more power?

those are the type of performance stuff. not just those, those types. if anyone can tell me of stuff they've done to their cars and still passed emissions (for those of us who are unlucky enough to live in an emissions state) thanks for any info
