Here's what you should do:
1) K&N or KKM ($50 or $90)
2) Borla, Bassani, or Custom Catback (~$600)
3) Koni yellows/Eibachs (~$850)
4) MSDS headers ($550)
5) 3L swap ($1750)
6) Repeat the above for me! Don't worry, I'll pay the difference!
Seriously though, you might want to hold off on the "visually obvious" mods until after your warranty runs out. New intake/filter is a good first step- plus it's easy to swap out in case your dealer's a d!ck.
Happy modding and welcome...
