Recommended N/A mods for 21’ GT

Hey Mustang fam.

I’m looking to get some performance upgrades throughout this year as I finish paying off my car. I’ve always been on the side of “don’t mod the banks car” and I’m gonna be sticking to that, but I’m starting to get a list of mods together that I can start setting money aside for when I do finish paying off my loan. Probably before summer it will be paid off…that’s the plan baring any surprise financial issues that come up.

At first when I got my car I was already thinking of going all out and getting it turbocharged or supercharged but I’ve come to the conclusion that not only do I not need it, it would be financially dumb of me since it’s my daily, and it’s already expensive enough to just keep the tank full as it is paying almost 5.30/gal where I’m at.

I’ve come here to get some crowd sourced recommendations for upgrades and want to keep it N/A but I’m pretty new to modding cars so I’m looking for some insight and a push in the right direction.

Here is my current spec:

2021 GT Premium. Auto 10spd, Active Exhaust, Performance Pack, Enhanced Security pack, staggered set up 255 40R19 9.5 front, 275 40R19 10 rear.

Haven’t don’t anything to it yet so it’s essentially a stock GT with most options (no magnaride or NitePony pack) pushing 480hp.

I know that there’s a few things I could do to squeeze a bit more horses out of it. I know I could get a CAI, tune, LT headers and stuff like that. Are there other upgrades that anyone could recommend to look into to make sure I don’t break something after I do some mods? I know super/turbo charging requires a lot more supporting mods but that’s not the route I’m planning to go just basic bolt ons to maybe see if I can get it to over 500 hp (on paper, I know it won’t be 500whp)

Any recommendations would be appreciated!
