windows up at idle 68 average
windows up cruise (~3k rpm ~60mph) ~78 average

I too had issues with the dynomax setup. It didn't like my 2.3 stroker with cams . That is why I went with the boost acutated cutout and stock catback.
I did get the rattling under control. I adjusted the wastegate arm that actuates the valve. The rattle is just about gone.

I went to SoundPerformance.com and the piece you have they are selling for $399. That seems outrageous.
Anyhow, my db readings:
Tsudo 3" CBE
Perrin 3" DP
3" Test Pipe
95 db at idle 1000 RPM
100+ db at 3500 RPM
Stock CBE with stock cat
75 db at idle 1000 RPM
Lost 25 hp/tq and 700 RPM spool up

I use the db volume app on my iPod touch. I get 40 db in a quiet room. 80 db in cabin idling, 90 db in cabin cruising (drivers seat) which goes up to 95 db rear seat (3500 rpm highway with windows up). I need to make my car quieter for sure. ~20" at idle the exhaust produces 94 db.
