If you decide to trade-in, I recommend you return it back to stock as much as possible. Sell your aftermarket parts locally and online. The dealership will frown on mods and offer you less... particularly since they cannot resell it as 'pre-owned certified' because to do so it has to be 100% stock.
I believe that if you have a universal type PCV Catch Can for a Camaro, it can be used on either V6 or V8 2010+ Camaro models. As for your CAI, the elbows differ from V6 to V8, but contact the manufacturer, they may be able to sell you a la carte pieces you'll need. If not just sell it privately and buy yourself a new CAI once you have the SS.
Good luck! Whether you upgrade or not, you still have a Camaro... true & blue.
