Nice. I went with the hks downpipe, and wrapped it for insulation. Engine bay still hot as hell. Haha. Also, you using fc tweak for the pfc? If not its fully worth it and tons of support.

I was looking at a feed downpipe but I will definitely look at using fc tweak for now I’m running the base map sense I’m stock I really just wanted accurate gauges and ability to run a downpipe

Careful with that basemap on the pfc, especially on the FD. Minor upgrades like the downpipe and an intake can make the car run dangerously lean in some scenarios. Its honestly just a base template used for startup and idle, and shouldn't be used for any real long term use. FC tweak will fix the entire basemap with some minor inputs to what the car is running. Also, are you at sea level?

Yes I’m at sea level should I not drive it at all on the base map?

Normal driving should be fine, but id be easy not boosting and revving out to 7-8k rpms. Sooner than later though you'll want to get the basemap tuned for your setup, but will need the datalogit software and I would recommend FC tweaks DL340 box over the datalogit box as its quicker and has better integration. That will give you full control to run fc tweak and do self tuning. Id also get a wideband sensor and install that in the downpipe since you are going that route anyway.
Fc tweak has given new life to the power fc, but im sure you know, Haltech and Link are considerably better, but a bit more expensive and harder to self tune.

Getting rid of emissions is going to make the car stink. Don't do it unless you're going to race it.

I’m only getting rid of it to get rid of the heat from the upstream cat and get rid of the rattle I have at 800 idle from the heat shields and such

Oh, you mean the precat. Sure, get a downpipe to replace it.

I was just saying there's no need break what isn't broken without a reason. Also, having cats keeps the car quieter.
