Also,
If your looking for performance, STS (Squires Turbo Systems) is developing single and twin turbo's for both V6 and V8 Camaro's. Twin for the C6 was about $8k installed. If you can install an exhaust system, you can install their turbo system and save yourself some $$. Take it to your local performance shop for a killer tune and you'll be VERY happy with your Camaro.
My system will be on just as soon as I make it through the break in period.
Choose wisely, it gets really expensive when you don't.
