2007 Imapla LT Upgrade Ideas

I just purchased a 2007 Chevy Impala LT. 3900 3.9 L V-6. The purpose of this post is to get some ideas, suggestions and thoughts on the possible upgrades. Here are my thoughts (not in any specific order).

1. Cool Air Intake
2. Flow Master Super 44
3. Headlights and Tail lights
4. Grill
5. Wheels and Rims
6. Paint
7. Window Tint
8. In dash unit and speakers

My mission is to get as much rumble and performance out of the current engine in the car. I am setting a $6000 budget for this project. My plan is to use the same size tire when upgrading. Maybe an 18 inch. I guess my biggest question is would it be worth putting a cool air intake and flowmasters on a 3.9 liter V-6? I am not trying to win any races but would like to be able to sound like I can when I roll past you. Now I would expect a performance boost with the upgrades. I want to run it by the community and get some thoughts.

Thanks in advance.
