Very new to this so I don’t really have a good idea what I’m actually looking at. $5000 budget. What are the best mods I can do to gain the most power? Any help is appreciated!

 

A free flowing exhaust is where I'd start. You'll notice a big difference with your butt dyno right away. Intake wouldn't hurt but they're pretty good from factory. If you want to really open things up, get catless downpipes. Although it's best to get a tune if you run downpipes.

Lightweight wheels and good tires will reduce your rotating mass making it feel like you have a little more power.

First link is to Intakes and exhaust; second is tuning options. $5k is a pretty good budget to do a full bolt-on build. Highly recommend going with a sway bar upgrade; it will drastically improve understeer/oversteer of the car; pending if you have a RWD or AWD model.
