I'm going to sell the 2005 V and make the Lightning my mod toy.

Yes, I know that search is my friend, but... if anyone is willing to point out the best initial mods for me I would truly appreciate it. I'm thinking I'll start with CAI, cat-back, upper and lower pulley, and tune. What are the current fave exhausts, pulleys, and intakes? Anything else that obviously (to you guys) should be done in an initial go? Gotta stay CA smog friendly so things like long pipes won't fly.

Bonus points for suggestions on internals.
