Flowmaster Super 10 opinions

Had super 10's on my 340 powered 65 cuda for a season & they were just to loud for me. Hearing radio or communication with passenger are impossible. Switched to super 40's and still loud but a little more subtle. Here is video of my car with the 40's and radio playing for reference.
