Mine sounds great. At idle, on a cold start it sounds better than my parents 2003 Vette (IMO). A very nice low grumble! But it gets quieter when it warms up. The resonator definitely quiets it down. At low rpms, going about 20-40, the sound is noticeable. At HWY speeds it isn't.
I still have to let someone else drive it so I can hear exactly what it sounds like outside the car...but I have to find someone I trust to drive my car. My brother therefore is out of the question.
I don't have a recording yet. Once I get a dig. camera will record it. But I'm very happy with it, and I don't even have my Hi-flow CAT yet
