to be honest the catback and header r my first so called real mods will my stock cat fit back on my exhaust the stock cat has an inlet and outlet of 1 7/8 and the new exhaust is 2 1/4 i was jus goin to buy one of the obd2 50 state legal hi flow cats off summit

good choice. as a recommendation, get a cat with floating flanges as it makes it much easier to bolt up. this recommendation comes from dyingwish. if you haven’t already done so, make sure to get 2.25" donut gaskets for it as well.
