Hi there!! I'm new to this 911 ownership, I would like to get some advice on downpipes. Looking to improve sound+ throttle response, currently debating between these two options; to go catless or 100/200cell. Any inputs and information will be very much appreciated!!! Thank you

Congrats, there are other threads about this topic, including the one below. Several people here have bought 200 cell sport cats, particularly the one made by Soul Performance Products. I have one on the way as well:

To my knowledge, there aren't many people in this forum who have gone catless

looks like the Porsche products listed are for the Turbo and Turbo S only.

With a 911, you’ll want to do sport cats. That will get you the sound that you’re looking for. Keep the original cats for when you sell the car.

Catless? You’re going to get the noise that you’re looking for from the sport cats. For a car driven on the street, I’d run with some kind of high efficiency/sport cat setup, because 1) Catless literally smells, 2) You’re going to draw attention to yourself from law enforcement and an increasing number of states/locales are cracking down on that kind of modification, 3) You’re much more likely to run into warranty issues running a catless setup.
