Any Suggestions on my new celica? :)

Recently bought a 2001 Celica Gt.
it already has an exhaust system welded underneath not sure what brand.
Has a carbon fiber wing sitting on the trunk. Again not sure what brand.
Has DIP rims all four set
And I recently installed some blue LEDs for my headlights.
No mods to the engine.
Paint is in good shape.
Has a pioneer stereo in the dash.
Brand new rotors and brake pads.
So my question is any suggestions on what to do next for my Celi?? Really happy about buying this car . Yotagang 👌
