Just got this installed ~1 week ago. It is perfect for me. Not too loud but definitely know it's there. If gm performance exhaust is 5/10 loud this would be 6.5/10 and S-type would be 7/10 loud. Sounds better than the Borla S-Type IMO. As another user stated it is not raspy sounding, but instead just straight up deep and mean!
Zero to little drone. If there is any, i'm not noticing it!
Not sure why this isn't a more popular option, but it def should be!
