I would do either headers, or the H pipe.
Both will make your car unbearably loud.

I did headers into the stock resonator/ae 1st.
Then I replaced the stock resonator with an even larger resonator making it very quiet with excellent tone and volume.. I get alot of compliments.

here is headers/stock re/ae

And here is headers /larger resonator/stock ae cold start in quiet…

That sounds amazing!!! Right now I have the roush H-pipe. OEM valved and the tone is deep. I just want more volume and it’s just as important to have no rasp. Maybe I’ll have to put in some vibrant resonators with headers.

You will get CEL for too rich of exhaust. You need a tune for that and the air timing delay of the AFR reading precat. .

Off-road will be considerably louder than catted. With active exhaust, you can expect off-road + open valves to be LOUD.
I would go with catted, personally, but it really is up to the end user on what their preference is.
We have SW on sale right now, some of the best pricing I have seen on these headers:

One other thing to consider: what other mods are you looking to do? Is a supercharger in your plans? May sway which way you decide to go.
