the single midpipe is the best starting point in my opinion. if you are keeping the downpipes stock, get the non-res option.
if you are upgrading the downpipes, get the resonated midpipe

Adding to above…
And if you think you’ll do downpipes in the future you could get the resonators on the single midpipe now. That way it will reduce rasp if/when you switch to DPs.

Thank you Mike. I think I’m landing on 200 cell catted with single resonated keeping the stock box for now. The only thing I’m worried is that the 200 cell catalysts blow out?

that's an excellent setup.

if you get a good brand, your downpipes will last longer than you are going to own the car.

I’m thinking of starting with a DP since the rest of the exhaust system does little to nothing. I do not like rasp, excessive burbling, and prefer deep tone. Should I go resonated or 200 cell catted? If I go resonated thinking of keeping secondary cats (therefore no single pipe) to cut the smell/fumes. Thoughts?

GAWWD DAMN I love your whole set up especially the wheel color for some reason is mesmerizing

Stay away from those super aggressive gunshot burbles and you should be just fine. Those explosions are not great for cats.
