I just put a downpayment a 2006 ss/sc. I have a few questions the dealer couldnt answer. The car has been modified I just dont know how much. The exhaust is very very loud. I looked under it and it appeared to have a straight pipe with a little resinator at the end. very loud and very ricey. It has a cold air intake. That I can see, my question is there a way for me to identify if a stage change? It also has a couple of oddities like a little box under thed dash, at first apperance it looked like a radar detector, once powered on it had a lighting system under the dash that grew brighter and softer with the beat of the radio. It also has a gaurded switch ???? that I cant find a use for. Any help would be appreciated. Thanks

 

look at the pulley on the super charger to see if its stock
