I'm new to the community and purchased a 2010 cts-v with 91k miles. The car runs good, a little rough idle even after spark plug change but overall pretty darn good. After buying the car I read about the supercharger issues and just my luck it's passed the 10 year or 120k miles. The sound wasn't too bad at first, and the marble sound is spot on how mine sounds. The sound has gotten a little louder and I will be taking off the supercharger belt later to see if it is thebsupercharger making the noise. I'm 99% sure it is so I was wondering if I switch to the solid iso that everyone speaks of will this fix the issue or does the supercharger need to be replace because the sound means damage is already done? Also any recommendation for brand of solid iso? Car is completely stock, as far as I know.

Welcome and remember the search function is extremely valuable. Probably is your isolator but can never be sure.
