what DP + Exhaust combo will pass emissions?

So i moved to Texas from FL and in FL we don't have emissions... before i would just buy everything straight pipe with no cats and call it a day. Now i have to be a bit more mindful...

anyone know the right combo(s) regarding catless/catted downpipes, exhaust, primary, seconday cats, etc., so that i can still pass emissions?

I was thinking something like catless downpipe, keep both primary and seconday cats, and just get an axle back exhaust like the BMW PE. would this setup pass emissions?
