Default Full Exhaust Upgrade Advice

First off I have a 2015 Civic Ex Sedan, I know it is the base model, but I still want to mod it. So far I have add a cold air intake, throttle body spacer, and full exhaust 2.5". Now I am looking for the next step in making my emissions system even more powerful. I basically need help finding what upgrades I need to purchase to fully open my exhaust. From what I have heard I now need, a header, downpipe, and a catalytic converter. I dont need exact manufacturer names of products but if i could get advice on if im missing anything else that I may need, i.e. air sensors etc.
