Performance or Cosmetic? Cosmetic is a personal choice so that's your call. I have colorshift halos in my car so I can get my halos to turn any color. If you want that, I'd recommend the jdp color changing package since you don't have to crack your headlights open with their option. There are loads of body kits, spoilers, wheels, and just about anything else you can stomach! One of the perks of having a Camaro!!!
Performance: This one is a bit different. Again, this is a personal choice but I can give you some advice. Since you have a 2010, you have all the options I have. I've done tons of research.
Cold air intakes - The big three right now are... Vararam, Cold Air Inductions, and Injen. They all put out about the same power but it really depends on what you want.
Exhaust is a personal choice but if you go to the v6 llt section, one of the first threads you will see is a compilation of every single exhaust setup every tried and recorded for this car.
Anything specific you want me to answer? I'm here to help
