I just bought my car over a few weeks ago and by looking through YouTube and forums I assumed my car was a stage 1..but my cousin believes its a stage 2though...it already came with k&n typoon coldair and after market full catback which has the chevy logo imprinted on the tip...so yeah its a dumb question since I dont know really much about cobalts but how can I find out if it is really a stage 2? Dont judge me lol

 

is it a SS/SC or SS/TC?

 

Blue bolts on your pulley and it will have 77.9mm stamped on it if its a GM Stage 2 kit

 

the catback you have is the GMPP touring based on that muffler

 

Its a 07 ss/sc and yes its a gmpp exhaust

 

besides the bolt colors on the pulley, if your pulley is pressed on and not bolted on, its not a stock pulley

 

Stock pulley is pressed on.

Aftermarket or GM Stage kit pulleys are bolted on.

 

woops, i meant its a stock if its pressed on.

 

Just wanted to clarify

 

i miss the sc :/
