Ok so right now my Cobalt SS/SC has GMPP exhaust, Injen intake and Ingalls Torque damper. I have saved enough money to get myself a stage 2 kit in the spring. But my question is this. What else is their to get after the stage 2 kit that doesn't void the warranty? Thanks guys!

 

One of my smoothflow pulleys that fit the GM stage 2 hub. Then just put the GM pulley back on if you need to take it to the dealer.
